procedures, misuse or misapplication of the device, or ignoring specifications and recommendations could
result in increased risk of harm to users, patients and bystanders, or damage to the device.

 Device captures and presents data reflecting a patient’s physiological condition that when reviewed by a trained

physician or clinician can be useful in determining a diagnosis; however, the data should not be used as a sole
means for determining a patient’s diagnosis.

 Users are expected to be licensed clinical professionals knowledgeable about medical procedures and patient

care, and adequately trained in the use of this device. Before attempting to use this device for clinical
applications, the operator must read and understand the contents of the user manual and other accompanying
documents. Inadequate knowledge or training could result in increased risk of harm to users, patients and
bystanders, or damage to the device. Contact Mortara service for additional training options.

 To ensure that electrical safety is maintained during operation from AC (~) power, the device must be plugged

into a hospital-grade outlet.

 Only use parts and accessories supplied with the device and/or are available through Burdick/Mortara/Quinton.
 Patient acquisition devices intended for use with the device include series resistance (9 Kohm minimum) in

each lead for defibrillation protection. Patient acquisition devices should be checked for cracks or breakage
prior to use.

 Conductive parts of the Patient acquisition device, electrodes, and associated connections of type CF applied

parts, including the neutral conductor of the Patient acquisition device and electrodes, should not come into
contact with other conductive parts including earth ground.

 ECG electrodes could cause skin irritation; patients should be examined for signs of irritation or inflammation.
 To avoid the possibility of serious injury or death during patient defibrillation, do not come into contact with

device or Patient acquisition devices. Additionally, proper placement of defibrillator paddles in relation to the
electrodes is required to minimize harm to the patient.

 This device does not automatically switch between direct or wireless Patient acquisition devices. Clinician

must choose Patient acquisition device before ECG acquisition. If your device is equipped with a receiver for a
wireless Patient acquisition device, always make sure that you are receiving data from the expected module.

USER SAFETY INFORMATION

 This device was designed to use the electrodes specified in this manual. Proper clinical procedure must be

employed to prep the electrode sites and to monitor the patient for excessive skin irritation, inflammation, or
other adverse reactions. Electrodes are intended for short-term use and should be removed from the patient
promptly following testing.

 To avoid potential for spread of disease or infection, single-use disposable components (e.g., electrodes) must

not be reused. To maintain safety and effectiveness, electrodes must not be used beyond their expiration date.

 A possible explosion hazard exists. Do not use the device in the presence of a flammable anesthetic mixture.
 Where the integrity of external protective earth conductor arrangement is in doubt, the device shall be operated

from its internal electrical power source.

 To improve immunity to potential interfering electromagnetic signals, shielded cabling is recommended when

connecting the device to a network.

 Medical devices have been designed to have a higher degree of protection against electric shock than, for

instance, information technology equipment because patients often are connected to multiple devices and also
may be more prone to the adverse effect of electric currents than healthy persons. All equipment that is
connected to the patient, can be touched by the patient, or can be touched by another person while that person
touches the patient at the same time, should have the same level of protection against electric shock as medical
equipment. The ELI 280 is a medical device that has been designed to be connected to other devices for the
purpose of receiving and transmitting data. Certain measures must be taken to prevent the risk of excessive
electric current flow through the operator or patient when connected:

 All electrical equipment that is not medical electrical equipment must be placed outside of the “patient

environment,” defined by applicable safety standards to be at least 1.5 meters (5 feet) from the patient.

Alternatively, non-medical equipment may be provided with additional protection such as an additional
protective earth connection.

 All medical electrical equipment that has a physical connection to the ELI 280 or the patient, or is in the

patient environment must comply with applicable safety standards for medical electrical devices.

 All electrical equipment that is not medical electrical equipment and has a physical connection to the

ELI 280 must comply with applicable safety standards, such as IEC 60950 for information technology
equipment. This includes information network equipment connected through the LAN connector.

 Conductive (metal) parts that can be touched by the operator in normal use and that are connected to non-

medical equipment should not be brought into the patient environment. Examples are connectors for

shielded Ethernet or USB cables.

 If multiple devices are connected to each other or to the patient, device chassis and patient leakage

currents may be increased, and should be measured for compliance with applicable standards for medical
electrical systems.

 Avoid the use of portable multiple socket outlets. If used and not compliant with medical electrical

device standards, an additional protective earth connection is required.

 To prevent electric shock due to unequal ground potentials that may exist between points of a distributed

network system or fault conditions in external network connected equipment, network cable shielding
(where used) must be connected to protective earth ground appropriate to the area where the device is used.

USER SAFETY INFORMATION

10

 The device has not been designed for use with high-frequency (HF) surgical equipment and does not provide a

protective means against hazards to the patient.

 When the 40 Hz filter is used, the frequency response requirement for diagnostic ECG equipment cannot be

met. The 40 Hz filter significantly reduces high-frequency components of the ECG and pacemaker spike
amplitudes, and is recommended only if high-frequency noise cannot be reduced by proper procedures.

 The quality of the signal produced by the device may be adversely affected by the use of other medical

equipment, including but not limited to defibrillators and ultrasound machines.

 For proper operation and the safety of users or patients and bystanders, equipment and accessories must be

connected only as described in this manual. Do not connect a telephone line cable to the LAN connector.

 Some Burdick electrocardiographs can be equipped with a GPRS (cellular modem) or wireless LAN (WLAN)

module for transmitting ECG records. Device labeling and the presence of an antenna port will indicate if your
device is equipped with such a module. If so equipped, the following notices apply:

 The WLAN identification can be found on a label on the bottom of the device.

 Quatech, Inc. Model WLNG-AN-MR551: 2400 MHz

(model subject to change without notice)

 Use of the WLAN module may interfere with other equipment operating in the vicinity. Check with local

authorities or spectrum management officials in your facility to determine if restrictions apply to the use of this
feature in your area.

●

Do not transmit via the WLAN module with a missing or damaged antenna. Replace a damaged antenna
immediately.

 Use only the antenna supplied for use with this device. Unauthorized antennas, modifications, or attachments

could damage the WLAN module and may contravene local RF emission regulations or invalidate type
approval.

 To ensure compliance with current regulations limiting both maximum RF output power and human exposure

to radio frequency radiation, a separation distance of at least 20 cm must be maintained between the device's
antenna and the head and body of the user and any nearby persons at all times. To help prevent degradation of
RF signal and to avoid excess RF energy absorption, do not touch the antenna during data transmission.

 The WLAN module complies with applicable RF safety standards including standards and recommendations

for the protection of public exposure to RF electromagnetic energy that have been established by governmental
bodies and other qualified organizations, such as the following:

 Federal Communications Commission (FCC)
 Directives of the European Community
 Directorate General V in Matters of Radio Frequency Electromagnetic Energy

Caution(s)

 To prevent possible damage to the touchscreen, do not use sharp objects to touch the screen icons, only use

fingertips.

 Do not attempt to clean the device or patient acquisition device by submersing into a liquid, autoclaving, or

steam cleaning as this may damage equipment or reduce its usable life. Wipe the exterior surfaces with a warm
water and mild detergent solution and then dry with a clean cloth. Use of unspecified cleaning/disinfecting
agents, failure to follow recommended procedures, or contact with unspecified materials could result in
increased risk of harm to users, patients and bystanders, or damage to the device.

 No user-serviceable parts inside. Screw removal by qualified service personnel only. Damaged or suspected

inoperative equipment must be immediately removed from use and must be checked/repaired by qualified
service personnel prior to continued use.

 The rechargeable internal battery is a sealed lead-acid type and it is totally maintenance free. If the battery

appears to become defective, refer to Mortara Instrument Service Department.

 Do not pull or stretch patient acquisition device as this could result in mechanical and/or electrical failures.

Patient cables should be stored after forming them into a loose loop.

 Calibration of the display is required before initial operation of the unit. No special equipment is needed for the

proper operation or maintenance of the device.

 When necessary, dispose of the device, its components and accessories (e.g., batteries, cables, electrodes),

and/or packing materials in accordance with local regulations.

 Proper functioning backup items such as a spare patient cable, front-end device, display monitor, and other

equipment are recommended on hand to prevent delayed treatment due to an inoperable device.

Note(s)

 Patient movement may generate excessive noise that may affect the quality of the ECG traces and the proper

analysis performed by the device.

 Proper patient preparation is important to proper application of ECG electrodes and operation of the device.
 The algorithm detecting electrode misplacements is based on normal physiology and ECG lead order, and tries

to identify the most likely switch; however, it is advisable to check the other electrode positions in the same
group (limb or chest).

 There is no known safety hazard if other equipment, such as pacemakers or other stimulators, is used

simultaneously with the device; however, disturbance to the signal may occur.

 The display of a thick baseline while using the WAM wireless acquisition module (square waves on rhythm

printout) could be due to the WAM being turned off or having no battery, or the WAM being out of range or
experiencing a calibration error. Review the LED indicator on the WAM to ensure the unit is turned on and has
proper battery level. Ensure the WAM is paired correctly and is within recommended proximity of the
electrocardiograph, and/or power cycle the WAM to re-calibrate. Review the WAM user manual for details.

USER SAFETY INFORMATION

12

 The display of a thick baseline while using the AM12 acquisition module (square waves on rhythm printout)

could be due to an improper auto-calibration. Reconnect the AM12 or power cycle the electrocardiograph.

 A square wave on the display and rhythm printout could be due to the WAM, the AM12, or lead wires not

being connected to the patient.

 As defined by IEC 60601-1 and IEC 60601-2-25, the device is classified as follows:

 Class I equipment or internally powered.
 Type CF defibrillation-proof applied parts.
 Ordinary equipment.
 Equipment not suitable for use in the presence of a flammable anesthetic mixture.
 Continuous operation.

NOTE: From a safety perspective, per IEC 60601-1 and derivative standards/norms, this device is

declared to be “Class I” and uses a three-prong inlet to ensure an earth connection is made along with
mains. The ground terminal on the mains inlet is the only protective earth point in the device. Exposed
metal accessible during normal operation is double insulated from mains. Internal connections to earth
ground are functional earth.

●

This device is intended to be used in a hospital or doctor’s office setting, and should be used and stored
according to the environmental conditions specified below:

Operating temperature: +10° to +40°C (+50° to +104°F)

Wireless Data Transmission

 Some Burdick electrocardiographs can be equipped with an optional wireless data transmission module

(WLAN or GSM). Both these technologies use radios to transmit data to a Burdick receiving application. Due

to the nature of radio transmissions, it’s possible that, due to the characteristics of the environment where the

device is located, some other RF sources may interfere with the transmission generated by the device. Mortara
Instrument has tested the coexistence of the device with other devices that can interfere such as devices using
WLAN, Bluetooth radio, and/or cell phones. Although the current technology allows a very successful rate of

transmission, it’s possible that in some rare occurrences, the system may not perform at its best resulting in a

“failed transmission”. When this occurs, patient data will not be erased from the device nor stored in the

receiving application, ensuring that partial or corrupted data are not made available to the receiving station. If
the failure mode persists the user should move to a position where the RF signals may propagate better and
allow successful transmissions.

WLAN Option

 Wireless options transmit in the 2.4 GHz or 5 GHz range. Other nearby wireless devices in the same frequency

range may cause interference. If possible, move or turn off other devices to minimize potential interference.

 The Wireless LAN module used is compliant with the IEEE 802.11 a, b, g and n standards.
 Access Points used should respect IEEE 802.11 standards as well as local Radio Frequency regulations. The

device will scan the available channels and connect to the Access Point on the channel where the SSID that is
configured on the device is available.

 The following table shows the radio channels allocated in different geographic areas in the world. For bands

802.11b and g, only channels 1, 6, 11 and 14 (Japan only) are non-overlapping; for band 802-11a, channels

Powering the ELI 280

The ELI 280 is an AC powered and/or battery-operated device that can simultaneously charge the internal battery
while connected to AC power. It is recommended that it be plugged in to AC power when not in use. The device can
be operated on AC line voltage in the absence of a battery or in the event of an otherwise fully depleted battery.
When line voltage is removed the device immediately switches to battery power.

Operating on AC Power

 Plug the power cord into an AC wall outlet and into the AC connector on the rear panel of the ELI 280.

(Reference Figure 1-3.)

 When the ELI 280 is plugged into AC power, the green AC power LED indicator illuminates below the

ON/OFF button.

 Press the ON/OFF button when on battery power or touch the screen when on AC power to illuminate

the real-time display.

 A battery icon with an electrical bolt through the battery (seen in the upper right corner of the touchscreen

display) confirms that the device recognizes AC power and automatically controls battery charging.

NOTE: In the event of complete power loss due to battery removal or a hard reboot (depressing the
On/Off button for greater than 7 seconds) the ELI 280 will require a touchscreen recalibration and
time/date reset.

Operating on Battery Power

When operating on battery power, the battery icon changes to indicate its status:

 WHITE with a lightning bolt indicates the unit is charging on AC power.
 GREEN indicates battery is between 100% and 35% charge.
 YELLOW indicates battery is between 35% and 20% charge.
 RED indicates battery has less than 20% charge remaining. Immediately plug the ELI 280 into AC

power if the battery indicator turns RED.

NOTE: Automatic power down occurs approximately 10 seconds after the battery icon starts FLASHING
RED. Allow a minimum of 4 hours to recharge a battery to 85% of its charge level. Allow a minimum of
5 hours to recharge a battery to 90% of its charge level. The battery voltage may be viewed in the lower
right of the display by selecting the Configuration icon, then selecting About.

NOTE: A power down is accomplished by depressing followed by the Off button. To reboot the
unit from a complete power down, use the On/Off button.

CAUTION: If the battery voltage falls below 10.5 the device will automatically power down. After

recharging long enough for the battery voltage to rise above 10.5V the device may again be operated on
battery power. It may require up to 30 hours on AC line voltage to recharge the battery from its lowest
level. Routinely discharging a battery to the lowest level will severely shorten the life of the battery.

EQUIPMENT PREPARATION

36

Low Battery Failsafe Conditions

If the battery depletes to its lowest allowable level, the device will automatically power down to prevent permanent
damage to the internal lead-acid battery. Plugging in the AC cord just prior to shutdown and while the message
“Battery Low – Charge Unit” is displayed (10 seconds), will prevent the automatic shutdown.

If the battery depletes to its lowest allowable voltage while in ECG acquisition mode, the device will display the
message “Battery Low – Charge Unit”, and will continue normal operation until the user exits the ECG acquisition
mode. At that time the system will automatically power down allowing the user to complete an ECG already in
progress.

Power Status

The ELI 280 has three distinct power states: Power On, Stand-by, and Off.

Power On

Power is automatically turned on when the device is connected to AC power. While powered on the ELI 280
performs all of its functions including display, acquisition, printing and transmission of ECGs.

Stand-By

Stand-by occurs automatically after the system is left idle for longer than 5 minutes without user interaction. The
user can also force the unit into Stand-by by pressing the ON/OFF button briefly. To leave the Stand-by mode press
either the ON/OFF button or touch the display. All entered patient information is maintained in Stand-by mode and
if a patient is connected, the ECG can be acquired. Effectively, only the display is turned off in Stand-by mode.

Power Off

The ELI 280 automatically turns off after 15 minutes in Stand-by mode when on battery power and no patient is
connected. The ELI 280 also turns off when battery voltage becomes too low. The operator can force the ELI 280 to

Power Off state using the Off button in the screen. The ELI 280 will never automatically turn off when on
AC power.

Reboot

Depressing the ON/OFF button for longer than 7 seconds causes the ELI 280 to execute a hard reboot, preceded by
the display flashing three (3) times. This will reset the internal clock to the default time and date. A hard reboot
causes the system to prompt the user to recalibrate the touch function (by touching the red crosses one at a time),
and re-enter the date and time at the next power On. The user can bypass setting the date and time by selecting
DONE for immediate ECG acquisition, but this ECG will have the default acquired date. The user must then set the
correct date and time manually using the Configuration icon, or, if connected to an ECG management system, by

pressing to sync the date and time. The ELI 280 will also reboot after the battery has been disconnected.

NOTE: It is normally NOT NECESSARY to reboot the ELI 280. Only reboot the ELI 280 if the touch
screen needs calibration or if you have an unrecoverable problem.

Installing the WLAN Antenna

The ELI 280 with optional WLAN module ships with the antenna in the accessory box. To install the antenna,
perform the following:

1. Locate and remove the antenna from the accessory box.

2. Locate the antenna connector on the back of the ELI 280.

3. Mount the antenna on the connector by rotating the antenna clockwise. The antenna must be finger tight to its

connector.

4. Locate the built-in hinge and fold the antenna (it will now be at a 90° angle); continue to rotate the antenna

clockwise until it is placed vertically. This will guarantee the best signal for the WLAN module.

NOTE: To configure for WLAN use, see Connectivity and ECG Transmission.

Using the WAM or AM12 Acquisition Module

ECG acquisition and rhythm strip printing can also be performed at the WAM or the AM12 acquisition modules.
To use the WAM, refer to the WAM user manual. To use the AM12, refer to the AM12 short-form instruction card.

The ELI 280 must be configured at the factory for use with the WAM. If the ELI 280 is configured for use with the
WAM, the two devices must be paired to function properly. Please see the WAM user manual for pairing
instructions.

NOTE: WAM must be paired to electrocardiograph before operation. Refer to the WAM operators manual
for assistance in pairing the WAM.

NOTE: If no patient connection is detected after 15 minutes, the WAM will turn off.

RECORD AN ECG

Patient Preparation

Before attaching the electrodes, assure the patient fully understands the procedure and what to expect.

 Privacy is very important in assuring the patient is relaxed.
 Reassure the patient that the procedure is painless and that the electrodes on their skin are all that they

will feel.

 Make sure the patient is lying down and is comfortable. If the table is narrow, tuck the patient’s hands

under his/her buttocks to ensure their muscles are relaxed.

 Once all the electrodes are attached, ask the patient to lie still and to not talk. Explaining the process to the

patient may help relax them further and assist in acquiring a good ECG.

Preparing Patient Skin

Thorough skin preparation is very important. There is natural resistance on the skin surface from various sources
such as hair, oil, and dry, dead skin. Skin preparation is intended to minimize these effects and maximize the quality
of the ECG signal.

To prepare the skin:

 Shave hair from electrode sites if necessary.
 Wash area with warm, soapy water.
 Dry skin vigorously with a pad such as 2 x 2 or 4 x 4 gauze to remove dead skin cells and oil, and to

increase capillary blood flow.

NOTE: With elderly or frail patients take care to not abrade the skin causing discomfort or bruising.
Clinical discretion should always be used in patient preparation.

Patient Hookup

Correct electrode placement is important for acquiring a successful ECG.

A good minimum-impedance pathway will provide superior noise-free waveforms. High quality silver-silver
chloride (Ag/AgCl) electrodes similar to those provided by Mortara are recommended to be used.

TIP: Electrodes should be stored in an air-tight container. Electrodes will dry out if not stored properly
which will cause loss of adhesion and conductivity.

To Attach the Electrodes

1. Expose the arms and legs of the patient to attach the limb leads.

2. Place the electrodes on flat, fleshy parts of the arms and legs.

3. If a limb site is not available, place the electrodes on a perfused area of the stump.

4. Attach the electrodes to the skin. A good test for firm electrode contact is to slightly tug on the electrode to

check adhesion. If the electrode moves freely, it needs to be changed. If the electrode does not move
easily, a good connection has been obtained.

For accurate V-lead placement and monitoring, it is important to locate the 4

th

intercostal space. The 4

th

intercostal

space is determined by first locating the 1

st

intercostal space. Because patients vary with respect to body shape, it is

difficult to palpate the 1

st

intercostal space with accuracy. Thus, locate the 2

nd

intercostal space by first palpating the

little bony prominence called the Angle of Louis, where the body of the sternum joins the manubrium. This rise
in the sternum identifies where the second rib is attached, and the space just below it is the 2

nd

intercostal space.

Palpate and count down the chest until you locate the 4

th

intercostal space.

TIP: Entry of a lower case letter as the first letter in the last or first name will automatically be
capitalized.

Patient Demographics from Orders

The ELI 280 can download orders from ELI Link and E-Scribe and use the orders to populate demographic fields.
ECGs performed with orders contain links to those orders, and healthcare IT systems can automatically associate
(i.e. reconcile) the ECGs with the orders. To use orders, follow these steps:

1. Select from the real-time display.

2. Select MWL.

3. Touch the Query Code box and select a pre-configured query, or enter a short search string to perform a

patient-specific search.

4. Touch to retrieve the orders.

43

NOTE: Before downloading orders, the ELI 280 must have downloaded the Custom ID from ELI Link or
E-Scribe.

NOTE: Changing key patient identifying fields like the name, ID, sex, birthdate, etc. after selecting an
order will cause the ECG to be disassociated with that order and treated as an unordered test.

NOTE: The user must have Technician or Administrator permissions. If the user is currently a Guest, they
must log in as a Technician or Administrator or enter the ELI 280’s Technician password.

NOTE: When an ECG is linked to an order, the order’s scheduled time will be displayed at the bottom of

the patient demographics screen. If the time is not displayed, the ECG is not linked to an order.

Patient Demographics from Barcodes

The ELI 280’s optional barcode scanner supports popular symbologies such as Code 39, Code 128, Aztec, Data

Matrix, and PDF 417, just to name a few. If the facility’s patient ID bracelets encode several demographic fields,

like the patient’s ID, account number, name, sex, and birthdate, it may be possible to program the barcode scanner to

parse the individual values into the ELI 280’s patient demographics data entry form. Refer to the barcode scanner

user manual for instructions on setup and use.

When the barcode scanner is programmed to parse several demographic values from a barcode, the user may scan
the barcode from the main screen. When a barcode is scanned from the main screen and the ELI 280 detects
multiple lines of text, it automatically jumps to the patient demographics form and copies the values into the form.
From there, the user can fill in the remaining fields and touch Done to go back to the main screen.

Order Lookup with Barcodes

Patient ID bracelets often include barcodes that encode a single patient identifier. It could be the patient’s

permanent medical record number, admission ID, account number, or something similar. Scanning the barcode
symbol can be a convenient way to find the patient’s order. Assuming the ELI 280’s worklist has been recently

synchronized with the host, the user can scan the patient’s barcode from the main screen. When the ELI 280 detects

a single line of text in the barcode, it automatically jumps to the MWL page and copies the scanned value into the
Search Worklist box. If the patient’s order is in the list, it will be automatically selected. If the patient’s order is

not found, the worklist may need to be resynchronized with the host. In that case, consider touching the Sync
button to refresh the worklist and search for the order again.

Once the order is found and selected, touch Done to go to the demographics screen and fill in any remaining fields
before touching Done to go back to the main screen.

screen.

Display Filter:

The ECG filter can be set to any of the following frequency limits by pressing the desired choice on the touchscreen
display: 40 Hz, 150 Hz, or 300 Hz for ECG printouts. The Filter setting is printed at the bottom right corner of the
ECG printout. The Display Filter setting will also be used on the printed ECG, unless changed in the Acquired
screen.

WARNING: When the 40 Hz filter is used, the frequency response requirement for diagnostic

ECG equipment cannot be met. The 40 Hz filter significantly reduces high-frequency components of the
ECG and pacemaker spike amplitudes, and is recommended only if high-frequency noise cannot be reduced
by proper procedures.

NOTE: Changes to the ECG display setup for an individual ECG only take affect when a patient is
connected to the device.

ECG Acquisition and Printing with WAM or AM12

Control buttons located on the WAM and AM12 are available to initiate ECG acquisition and rhythm strip printing.
Refer to the WAM user manual or the AM12 short-form instruction card.

CONNECTIVITY AND ECG TRANSMISSION

ECG Transmission

The ELI 280 can transmit acquired ECG records to an E-Scribe system, ELI Link or to a third-party electronic
medical record (EMR) system. The interface to these systems can be via direct connection, factory installed
internal modem (optional), LAN or WLAN connection, using UNIPRO 32, or DICOM 32 protocols.

Before transmitting ECGs, certain configuration options must be set in system settings depending upon the
transmission media used and the electronic storage media being transmitted to.

NOTE: Telephone transmission is available with internal modem only.

NOTE: In order to properly connect to telephone lines, the ELI 280 internal modem needs to be set on the

proper country code. This is an internal setting and should not be confused with International calling
codes.

NOTE: Select at any time it appears to return to the real-time display.

In order to transmit ECGs the WLAN signal must be strong enough to transmit. WLAN performance may vary due
to changes in RF (radio frequency) properties at your site or to environmental conditions. Signal strength can be
measured using a utility available in the ELI 280 menu.

Testing RF signal strength

1. Select from the real-time display.

2. Select Advanced.

3. Select Network.

4. Signal strength displays as zero to five bars with zero being no RF signal strength and five bars being full

RF signal strength.

5. If an adequate signal is not being obtained, move to a location where more bars display before attempting

to transmit.

NOTE: Intermittent connectivity in certain areas of your facility often indicates the need to re-initiate the
transmission process. Consult the IT department at your facility or your Mortara Field Service Engineer
regarding modification of your WLAN to improve system performance.

NOTE: Ensure the system has been configured to the area network before attempting a RF signal strength
test.

Transmitting Records to the Cardiology Management System

To transmit a record to the cardiology management system, press Send from the acquired ECG view.

To transmit all un-transmitted records, press from the real-time display.

Patient Demographic Query (PDQ)

The ELI 280 can query the EMR for patient demographic information via HL7 A19 using the input of up to three demographic
criteria (ID, First Name, Last Name, or any combination of the three fields) for those institutions performing unordered ECG
tests, or do not have an interface to an electronic ordering system.

The ELI 280 performs a query based on the information input into the search fields. The more specific the information
input into the fields, the narrower the search. It is best practice to input as specific information as possible to return the
most specific result.

The PDQ feature may be enabled and used in combination with DICOM, or in an order-based environment.

Performing a PDQ:

1. Select

from the real-time ECG display, and then select the PDQ button.

2. Enter the ID, first name, last name, or any combination, then select SYNC.

3. When a single patient match is found, the ID screen is populated with the demographics of the result,
otherwise all patients matching the search criteria are listed.

4. Select the appropriate patient from the list if more than one option is available.

5. Select Done to proceed to the real-time ECG display for ECG acquisition.

Performing a PDQ with a barcode scanner:

1. While on the real-time ECG display, scan the patient barcode. The ELI 280 will automatically search for an
open order downloaded to the device, then it will search the list of ECGs stored on the device for a patient that
matches the field scanned, and if no patient is found, a patient demographic query using the entry scanned is
prompted.

2. When a single patient match is found, the ID screen is populated with the demographics of the result,
otherwise all patients matching the search criteria are listed.

3. Select the appropriate patient from the list if more than one option is available.

4. Select Done to proceed to the real-time ECG display for ECG acquisition.

Search Tools

The following are tools to assist in searching for the appropriate patient following a patient demographic query:

 Sort the results by Name, ID, Location, Room, or DOB by a tap on the column header. A second tap will

sort the list in reverse order.

 Use the double arrows (<< or >>) at the right center of the screen to move page by page through the list of

patients. The current/total number of pages is displayed between the double arrows.

NOTE: The PDQ feature on the ELI 280 may be used when enabled and the interface configured. See the ELI Link
manual for information regarding setup and configuration of the interface.
NOTE: When no match for a patient is found after a PDQ, the unit will remain in the Transmission Status screen
until the user selects Done.

of the synchronized time prior to acquiring ECGs

SYSTEM SETTINGS

72

File Encryption Key

If the Security Option is enabled then all stored files with patient and configuration information are encrypted with
the 256-bit Advanced Encryption Standard (AES). The File Encryption Key is used to encrypt the patient and
configuration information. If the File Encryption key is modified then all encrypted files are re-encrypted using the
new key. The Encryption Key cannot be blank. The Key can be up to 16 alphanumeric characters. Once the Security
Option is enabled and the stored files are encrypted there is no way to return the stored files to an un-encrypted
state.

If the device is booted and the configuration file is missing, a new configuration file will be generated with the
default configuration settings with the exception of the administrator and technician passwords. The
administrator and technician passwords will be set to random strings unknown to the user. The File Encryption
Key can be used as the administrator password to reset these passwords.

Delete Timeout

ECGs marked for deletion are still maintained in the device’s non-volatile memory until the memory is needed to
store new ECGs. The oldest ECGs are deleted to make room for the newest ECGs. If the local records retention
policy requires ECGs to be removed from memory sooner, this setting can be used to specify the number of days to
keep the ECGs prior to automatic deletion. Set to 0 days to delete the ECGs once they meet the criteria to be
marked for deletion.

The value can be set from any numeric value from 0 days to 9999 days.

Communications Encryption Key

If the Security Option is purchase then the device encrypts its communication with ELI Link to keep sensitive
information private. The transmitted data is encrypted with the 256-bit Advanced Encryption Standard (AES).
Leaving the key blank results in the device using the default encryption key built into ELI Link. If the local security
policy requires use of alternate keys, configure the same key in the device and ELI Link. The key can be up to 16
alphanumeric characters.

User Authentication

This setting specifies how the ELI 280 should authenticate individual users.

Off

This turns off user authentication. The ELI 280’s Technician and Administrator passwords
may be used to protect access to orders, stored ECGs, and the configuration settings.

This allows the user to enter a User Name so the device will prepopulate the Technician field

Local

when performing new ECGs, but no authentication of the user is performed against

network credentials from another system. The user must enter the ELI 280’s Technician or

Administrator password to obtain the respective permissions.

Network

This mode authenticates users over the network using Active Directory or LDAP and
determines their permissions according to security group membership as configured in ELI

Link.

NOTE: The LDAP or Active Directory domain for the user accounts and the security groups that are
considered ELI technicians and administrators are configured in ELI Link and are not configured or

stored on the ELI 280.

73

SYSTEM SETTINGS

User roles are configured in ELI Link by configuring the security whose members are considered guests,
technicians or administrators.

Anonymous Guest – the user has not been authenticated. The unknown guest may only acquire new

ECGs by manual entry of patient demographics. Their User Name will not be prepopulated into the

Technician field of new ECGs.
Known Guest – the user has been authenticated on the network with their User Name and Password,

but the user has not been granted Technician or Administrator permissions. The user has all
capabilities except access to advanced configuration items, directory, MWL and real time sync. The
user may only acquire new ECGs by manual entry of patient demographics. The Known Guest User
Name will be prepopulated into the Technician field of new ECGs.

Technician – the user has been authenticated on the network with their User Name and Password, and

the user has been granted Technician permissions. In addition to Guest permissions, this user may also

view orders and stored ECGs.
Administrator – the user has been authenticated on the network with their User Name and Password,

and the user has been granted Administrator permissions. In addition to Technician permissions, this

user may also change the ELI 280’s settings.

Auto Log Off

When user authentication is used, this setting specifies the number of minutes the ELI 280 may remain idle before it
automatically logs the user off. The device is idle when there is no patient connected and the screen is off. The user
may manually put the device into an idle state by lightly pressing the power button.

An authenticated user may also log off manually at any time by selecting the Settings button from the main screen
and selecting Log Off.

Note: The device is not considered idle and will not automatically log off the user when a patient is connected.

Configuration Settings: ECG

AC Filter

This selection allows the user to remove 60 Hz or 50 Hz interference on the ECG trace. The setting selected depends
on the line frequency in the host country. Always use the 60 Hz setting in the U.S. If AC interference is frequently
present on the ECG signal, make sure the proper AC filter frequency has been selected.

Filter

This selection allows the user to select the appropriate filtering for the desired trace results. The band-pass filter that
is selected attenuates higher frequency noise and affects the fidelity of the electrocardiograph as viewed on the
display and on the printed hard copy. The filter setting is printed at the bottom right corner of the ECG printout, and
may also be viewed on the upper right-hand corner of the real-time display. Settings include:

1. The 40 Hz print-filter (0.05 to 40 Hz) setting reduces the noise from frequencies above 40 Hz.

2. The 150 Hz print-filter (0.05 to 150 Hz) setting reduces the noise from frequencies above 150 Hz (default).

3. The 300 Hz print-filter (0.05 to 300 Hz) setting reduces the noise from frequencies above 300 Hz. This
setting provides the least filtering and highest fidelity ECG signal to the printed and displayed ECG; this
setting is recommended for pediatric ECG’s.

WARNING: When the 40 Hz filter is used, the frequency response requirement for diagnostic

ECG equipment cannot be met. The 40 Hz filter significantly reduces high-frequency components of the
ECG and pacemaker spike amplitudes, and is recommended only if high-frequency noise cannot be reduced
by proper procedures.

74

SYSTEM SETTINGS

NOTE: The plot-frequency filter does not filter the digitized signal acquired for interpretation of the ECG.

NOTE: The Filter setting can also be changed for a single ECG by touching anywhere on the ECG

waveform in the real-time or acquired view.

Interp

This selection allows the clinician to turn the ECG interpretation statements On/Off for presentation on the display
and/or plotted report.

NOTE: The ECG interpretations offered by the device are intended to be most relevant when used in
conjunction with a physician over-read and with consideration of all other relevant patient data.

Reasons

This selection allows the clinician to include additional information about the ECG interpretation on the printout.
Reasons statements are specific details that indicate why a particular interpretive statement was chosen. Reasons
statements print in brackets [ ] within the interpretive text. Reasons are only available if the interpretation statements
option is enabled. Turning the reasons statement function ON or OFF does not affect the measurements criteria or
the interpretive statement selected by the analysis program.

For Example:

Anteroseptal Infarct [40+ ms Q WAVE IN V1-V4]

“Anteroseptal Infarct” is the interpretive statement.
“40+ ms Q WAVE IN V1-V4” is the reason statement explaining the interpretive statement.

Append

This selection allows the user to add a status message or statement phrase to the ECG to be printed under the
interpretive text printout. The choices are “UNCONFIRMED REPORT” or “Reviewed by.”

Delete Rule

The Delete Rule allows the user to define how and when ECGs are automatically marked for deletion in the ECG
directory. ECGs can be marked manually or marked for deletion per the Delete Rule. ECG records are only fully
deleted from the directory when the directory becomes full. When the memory is full, ECGs that are marked for
deletion will be automatically deleted based on their acquisition date and time (first-in/first-out) to make room for
new ECG records. More than one ECG record may be removed from the directory to make room for the new
incoming record.

The Delete Rule selections are:

1. Post Plot = ECG is automatically marked for deletion after printing

2. Post Transmit = ECG is automatically marked for deletion after transmission

3. Post Plot/Transmit = ECG is automatically marked for deletion after transmission and printing

NOTE: A record may be permanently deleted by selecting the record, followed by selecting Erase from the
left side of the display. A window will be presented as “Erase ECG?” If you select Yes the record will be
permanently erased. If you select No the record will be maintained in the file.

Power Off the Device

To completely shutdown the device, disconnect the AC power cord then press the ON/OFF button. Such a
shutdown should always be performed prior to authorized repair of the device.

Test Operation

After cleaning and inspecting the device, proper operation of the unit may be confirmed by using an ECG simulator
to acquire and print a standard 12-lead ECG of known amplitude. Printing should be dark and even across the page.
There should be no evidence of print head dot failure (e.g., breaks in printing forming horizontal streaks). Paper
motion should be smooth and consistent during printing. Waveforms should appear normal with proper amplitude
and, without distortion or excessive noise. Paper should stop with perforations near the tear bar (indicating proper
cue sensor operation).

Recommendations to Biomedical Staff

Following any service to the device or when non-compliant operation is suspected, Mortara Instrument, Inc.
recommends the following procedures:

 Confirm proper operation.
 Perform testing to ensure continued electrical safety of the device

(use IEC 60601-1, ANSI/AAMI ES 60601-1, or IEC 62353 methods and limits).

 patient leakage current
 chassis leakage current
 earth leakage current
 dielectric strength or insulation resistance (mains and patient circuits, mains and signal input/output

part (e.g., USB), mains and protective earth)

Battery Maintenance

The device houses an internal, sealed lead-acid battery. When installed, the battery has a shelf life of approximately
six months without recharging. If the battery has been stored for a long period in a discharged state, it may not be
able to regain its capacity even if it is recharged.

For information about replacing the battery, please refer to the device’s service manual.

Mortara Instrument, Inc. and Burdick recommend that the device be plugged into AC power whenever possible to

maximize battery life and for the user to develop a habit of recharging the battery before the unit indicates a “low

battery” condition. (That is, reduced depth of discharge.) Battery life varies by how the battery is maintained and

how much it is used. For improved battery life, keep the electrocardiograph plugged in when not in use.

The sealed lead-acid battery will provide optimum life when the unit is fully charged after each use. When the
battery charge is depleted to its lowest level (10.6V), the device will automatically power down. To recharge a
battery from its lowest level to 85%, 4 hours of recharging may be necessary. To reach 90%, 7 hours of recharging
may be necessary. It may take longer to reach 100%. The device can be used with AC power while simultaneously
charging.
