1 Safety

1.1 Safety Information

WARNING

 Indicates a potential hazard or unsafe practice that, if not avoided, could result in death or serious injury.

CAUTION

 Indicates a potential hazard or unsafe practice that, if not avoided, could result in minor personal injury or

product/property damage.

NOTE

 Provides application tips or other useful information to ensure that you get the most from your product.

1-2 T1 Patient Monitor Operator’s Manual

1.1.1 Warnings

WARNINGS

 Before putting the system into operation, the operator must verify that the equipment, connecting cables

and accessories are in correct working order and operating condition.

 To avoid risk of electric shock, this equipment must only be connected to a supply mains with protective

earth. If a properly grounded power outlet is not available, operate the monitor on battery power.

 The equipment is not intended to be used within the Magnetic Resonance (MR) environment.

 Ensure that the patient monitor is supplied with continuous electric power during work. Sudden power

failure may lead to data loss.

 To avoid an explosion hazard, do not use the equipment in the presence of oxygen-rich atmospheres,

flammable anesthetics, or other flammable agents (such as gasoline).

 Before connecting the equipment to the power line, check that the voltage and frequency ratings of the

power line are the same as those indicated on the equipment’s label or in this manual.

 Do not open the equipment housings. All servicing and future upgrades must be carried out by the

personnel trained and authorized by Mindray only.

 Do not come into contact with patients during defibrillation. Otherwise serious injury or death could result.

 Do not rely exclusively on the audible alarm system for patient monitoring. Adjustment of alarm volume to

a low level or off may result in a hazard to the patient. Remember that alarm settings should be customized

according to different patient situations and always keeping the patient under close surveillance is the most

reliable way for safe patient monitoring.

 PATIENTS WITH A PACEMAKER – On ventricular paced patients, episodes of Ventricular Tachycardia may not

always be detected. Do not rely entirely upon the system’s automated arrhythmia detection algorithm.

Keep pacemaker patients under close surveillance.

 The physiological data and alarm messages displayed on the equipment are for reference only and cannot

be directly used for diagnostic interpretation.

 To avoid inadvertent disconnection, route all cables in a way to prevent a stumbling hazard. Wrap and

secure excess cabling to reduce risk of entanglement or strangulation by patients or personnel.

 Do not touch the equipment’s metal parts or connectors when in contact with the patient; otherwise patient

injury may result.

 Never mix patient electrode types or brands. Dissimilar metals or other incompatibilities may cause

considerable baseline drift and may increase trace recovery time after defibrillation.

 To reduce the hazard of burns during high-frequency surgical procedure, ensure that the monitor’s cables

and transducers never come into contact with the electro-surgery unit (ESU).

 The neutral electrode of the electro-surgery unit (ESU) shall properly contact the patient. Otherwise, burns

may result.

 Magnetic and electrical fields are capable of interfering with the proper performance of the equipment. For

this reason make sure that all external devices operated in the vicinity of the equipment comply with the

relevant EMC requirements. Mobile phones and X-ray equipment are a possible source of interference as

they may emit higher levels of electromagnetic radiation.

T1 Patient Monitor Operator’s Manual 1-3

4.1 Admitting a Patient

The monitor displays and stores physiological data in trends as soon as a patient is connected. This allows you to

monitor a patient that is not admitted yet. However, it is recommended that you fully admit a patient so that you can

clearly identify them on reports and network devices.

To admit a patient:

1. Select [Main Menu]→[Patient Setup >>].

2. Select [Admit Patient].

If a patient has previously been admitted, a message [Are you sure to discharge the current patient and admit a

new patient?] pops up. Then select [Ok] to clear any previous patient data. If you do not erase data from the

previous patient, the new patient’s data is combined with the previous patient’s data. The monitor makes no

distinction between the old and the new patient data.

If no patient has been previously admitted, you can choose either:

 [Yes] to apply the data saved in the monitor to the new patient, or

 [No] to clear the data saved in the monitor.

3. In the [Patient Demographics] menu, enter the demographic details, of which:

 [Patient Cat.] allows the user to select patient size (Neo, Ped, Adu) which will determine the way your monitor

processes and calculates some measurements, and what safety and alarm limits are applied to your patient.

 [Paced] determines whether to show pace pulse marks on the ECG waveform. When the [Paced] is set to [No],

pace pulse marks are not shown in the ECG waveform.

4. Select [Ok].

WARNING

 Make sure the [Patient Cat.] and [Paced] fields always contain a value, regardless of whether the patient is

fully admitted or not.

 For paced patients, you must set [Paced] to [Yes]. If it is incorrectly set to [No], the monitor could mistake a

pace pulse for a QRS and fail to alarm when the ECG signal is too weak.

 For non-paced patients, you must set [Paced] to [No].

For details about patient paced status, refer to section 8.3.4 Checking Paced Status.

5 Managing Configurations

5.1 Introduction

When performing continuous patient monitoring, the clinical professional often needs to adjust the monitor’s settings

according to the patient’s condition. The collection of all these settings is called a configuration. Allowing you to

configure the monitor more efficiently, the monitor provides different sets of configurations to accommodate the

varying patient categories and departments. You can change the settings from a default configuration and then save it

as a user configuration.

The default configurations provided for your monitor are department-oriented. You can choose either from:

 General

 OR

 ICU

 NICU

 CCU

Each department has three different sets of configurations, one for each patient category, [Neo], [Ped], and [Adu]. For

the configuration items and their default values and user maintenance items, see Appendix C Default Configurations.

NOTE

 The configuration management function is password protected. The configuration management tasks must

T1 Patient Monitor Operator’s Manual 7-1

7 Alarms

Alarms, triggered by an abnormal vital sign or technical issue with the monitor as visually and audibly indicated to the

user.

WARNING

 A potential hazard can exist if different alarm presets are used for the same or similar equipment in any

single area, e.g. an intensive care unit or cardiac operating room.

 If your monitor is connected to a CMS, alarms can be controlled remotely. Remote suspension, inhibition,

and reset of monitor alarms via the CMS may cause a potential hazard. For details, refer to the CMS’s

operator’s manual.

For troubleshooting specific alarms, see appendix D Alarm Messages.

7.1 Alarm Categories

The monitor’s alarms are classified into two categories: physiological alarms and technical alarms.

1. Physiological alarms

Physiological alarms, also called patient status alarms, are triggered by a monitored parameter value that violates

set alarm limits or an abnormal patient condition. Physiological alarm messages are displayed in the physiological

alarm area. Refer to section 2.4 Display Screen for details.

2. Technical alarms

Technical alarms, also called system status alarms, are triggered by a device malfunction or a patient data distortion

due to improper operation or mechanical problems. Technical alarm messages are displayed in the technical alarm

area. Refer to section 2.4 Display Screen for details.

Apart from the physiological and technical alarm messages, the monitor will show some messages telling the

system status or patient status. Messages of this kind are included in the prompt message category and usually

displayed in the prompt information area. Some prompt messages that indicate the arrhythmia events are

displayed in the physiological alarm area. For some measurements, their related prompt messages are displayed in

their respective parameter windows.

7-2 T1 Patient Monitor Operator’s Manual

7.2 Alarm Levels

The monitor’s alarms can be classified into three seerity categories: high level, medium level and low level.

Physiological alarms Technical alarms

High level

Indicatess that the patient is in a life

threatening situation, such as Asystole,

Vfib/Vtac and so forth, and emergency

treatment is required.

Indicates a severe device malfunction or an improper operation

which could make it possible that the monitor cannot detect

critical patient status and thus threaten the patient’s life.

Medium

level

Indicates that the patient’s vital signs

appear abnormal and immediate

treatment is required.

Indicates a device malfunction or an improper operation, which

may not threaten the patient’s life but may compromise the

monitoring of vital physiological parameters.

Low level

Indicates that the patient’s vital signs

appear abnormal and immediate

treatment may be required.

Indicates a device malfunction or an improper operation, which

may compromise a certain monitoring function but will not

threaten the patient’s life.

7.3 Alarm Indicators

When an alarm occurs, the monitor will prompt the user through visual or audible alarm indicators.

 Alarm lamp

 Audible alarm tones

 Alarm message

 Flashing numerics

7.3.1 Alarm Lamp

If a technical alarm or physiological alarm occurs, the alarm lamp may flash. The color and flashing frequency correspond

to the alarm level as follows:

 High level alarms: the lamp quickly flashes red

 Medium level alarms: the lamp slowly flashes yellow

 Low level alarms: the lamp lights yellow without flashing

7.3.2 Alarm Messages

When an alarm occurs, an alarm message will appear in the technical or physiological alarm area. For physiological

alarms, the asterisks (*) before the alarm message match the alarm level as follows:

 High level alarms: ***

 Medium level alarms: **

 Low level alarms: *

T1 Patient Monitor Operator’s Manual 7-3

Additionally, the alarm message has a different background color which corresponds to the alarm level:

 High level alarms: red

 Medium level alarms: yellow

 Low level alarms: yellow

You can view the alarm messages by selecting the physiological or technical alarm area. Refer to 2.4 Display Screen for

details.

7.3.3 Flashing Numeric

If an alarm triggered by an alarm limit violation occurs, the numeric portion of the measurement in alarm will flash every

second, and the corresponding alarm limit will also flash at the same frequency indicating the high or low alarm limit is

violated.

7.3.4 Audible Alarm Tones

The alarm tone is distinct from the heart beat tone, keystroke tone and pulse tone in frequency. This monitor has three

alarm tones and patterns: ISO, Mode 1 and Mode 2. For each pattern, the alarm tones identify the alarm levels as follows:

 ISO pattern:

 High level alarms: triple+double+triple+double beep

 Medium level alarms: triple beep

 Low level alarms: single beep

 Mode 1:

 High level alarms: high-pitched single beep

 Medium level alarms: double beep

 Low level alarms: low-pitched single beep

 Mode 2:

 High level alarms: high-pitched triple beep

 Medium level alarms: double beep

 Low level alarms: low-pitched single beep

NOTE

 When multiple alarms of different levels occur simultaneously, the monitor will select the highest level

alarm, light the alarm lamp and give alarm sounds accordingly, while all the alarm messages scroll on the

screen.

 Some physiological alarms, such as Asystole, are exclusive. They have identical alarm tones and alarm lights

with normal high level physiological alarms, but their alarm messages are displayed exclusively. That is,

when an exclusive physiological alarm and a normal high level physiological alarm are triggered

simultaneously, only exclusive physiological alarm message will be displayed.

7-4 T1 Patient Monitor Operator’s Manual

7.3.5 Alarm Status Symbols

Apart from the aforementioned alarm indicators, the monitor still uses the following symbols telling the alarm status:



indicates alarms are paused.



indicates alarm is reset.

 indicates the alarm sound is turned off.



indicates individual measurement alarms are turned off or the system is in alarm off status.

 Interval between medium level alarm tones: 5 s

 Interval between low level alarm tones: 20 s

 Mode 2:

 Interval between high level alarm tones: 1 s

 Interval between medium level alarm tones: 5 s

 Interval between low level alarm tones: 20 s

WARNING

 When the alarm sound is switched off, the monitor does not provide any audible alarm tones even if a new

alarm occurs. Therefore the user should be very careful about switching off the alarm sound.

 Do not rely exclusively on the audible alarm system for monitoring. Adjustment of alarm volume to a low

level may result in a hazard to the patient. Always keep the patient under close surveillance.

7-6 T1 Patient Monitor Operator’s Manual

.4.5 Setting the Reminder Tones

When the reminder tone is switched on and a physiological or technical alarm condition exists, the monitor gives a

periodic reminder tone in the following cases:

 When the alarm volume is set to zero, a high, medium, low, or technical audible alarm indication will be generated

at the set reminder interval until the alarm condition is cleared.

 When the alarm condition has been acknowledged (e.g. pressing the Alarm Reset button), a high, medium, or low

audible alarm indication will be generated at the set reminder interval until the alarm condition is cleared.

 When the alarm system has been permanently paused (e.g. pressing the Alarm Pause button with the Alarm Pause

Time set to Permanent), an Alarm Paused audible alarm indication will be generated at the set reminder interval

until the alarm condition is cleared or the alarm system re-enabled.

To set the reminder tones:

1. Select [Main Menu]→[Maintenance >>]→[User Maintenance >>]→enter the required password.

2. Select [Alarm Setup >>] to enter the [Alarm Setup] menu.

3. Set the [Reminder Tones] to [On], [Off] or [Re-alarm]. When [Re-alarm] is selected, the acknowledged

physiological alarms and technical alarms marked with “√” will be re-generated after the [Reminder Interval] if the

alarm condition persists.

To set the interval between reminder tones, select [Reminder Interval] and then select [1min], [2min] or [3min].

In addition, you can set the volume of alarm reminder tones. To set the alarm reminder tone volume, select [Main Menu]

 Change other settings.

When a DPM CMS is used, the [Alarm Setup] menu displays as below:

T1 Patient Monitor Operator’s Manual 7-7

When a Panorama CMS is used, the [Alarm Setup] menu displays as below:

Refer to chapter 8 Monitoring ECG for how to change ST alarm settings, how to change arrhythmia alarm settings, and

how to set the threshold for some arrhythmia alarms.

7.5.1 Setting Alarm Properties for All Parameters

In the [Main Menu], select [Alarm Setup >>]→[Parameters]. You can review and set alarm limits, alarm switches, and

alarm level for all parameters.

WARNING

 Make sure that the alarm limits settings are appropriate for your patient before monitoring.

 Setting alarm limits to extreme values may cause the alarm system to become ineffective. For example, high

oxygen levels may predispose a premature infant to retrolental fibroplasia. If this is a consideration, do NOT

set the high alarm limit to 100%, which is equivalent to switching the alarm off.

 When monitoring patients that are not continuously attended by a clinical operator, properly configure the

alarm system and adjust alarm settings as per the patient's condition.

7.5.2 Adjusting Alarm Limits Automatically

The monitor can automatically adjust alarm limits according to the measured vital signs. When auto limits are selected,

the monitor calculates safe auto limits based on the latest measured values.

NOTE

 The On/Off column is only not visible with Panorama CMS.

7-8 T1 Patient Monitor Operator’s Manual

To get accurate auto alarm limits, you need to collect a set of measured vital signs as a baseline. Then, in the [Main

Menu], select [Alarm Setup >>]→[Parameters]→[Auto Limits] →[Ok]. The monitor will create new alarm limits based

on the measured values.

Before applying these automatically created alarm limits, confirm if they are appropriate for your patient in the [Alarm

Setup Menu]. If not, you can adjust them manually. These alarm limits will remain unchanged until you select auto limits

again or adjust them manually.

The monitor calculates the auto limits based on the following rules.

7.9 Latching Alarms

The latching setting for physiological alarms defines how alarm indicators behave if you do not reset the alarms.

 If you do not “latch” the physiological alarms, their alarm indications disappear when the alarm condition ends.
 If you “latch” physiological alarms, all visual and audible alarm indications remain until you reset the alarms. For

latched alarms the time when the alarm is last triggered is displayed beside the alarm message.

You can separately latch the visual indications or simultaneously latch the visual and the audible indications.

 When the visual indications are latched, the visual indications, including alarm lamp, alarm message and its

background remains when the alarm condition ends.

 When the audible indications are latched, the monitor issues alarm sounds when the alarm condition ends.

To latch a physiological alarm:

1. Select [Main Menu]→[Maintenance >>]→[User Maintenance >>]→enter the required password.

2. Select [Alarm Setup >>]→[Latching Alarms>>].

3. Select how you want to latch the alarms.

The rules for latching the alarms are:

 You can separately select [Latching Visual Signal].
 Selecting [Latching Audible Signal] simultaneously latches the visual signal.
 Selecting alarms of lower priority simultaneously latches the alarms of higher priority.
 The lethal alarms are latched by default. High, medium, and low priority alarms are unlatched by default.

NOTE

 Changing of alarm priority may affect the latching status of corresponding alarms. Please determine if you

need to adjust the latching status for the specific alarm when you have changed its alarm priority.

 When the alarm system is reset, the latched physiological alarms are cleared.

You can separately configure the latching of the Vtac alarm. To do so, follow this procedure:

1. Select [Main Menu]→[Maintenance >>]→[User Maintenance >>]→enter the required password.

2. Select [Alarm Setup >>]→[Latching Alarms>>].

3. Set [Vtac Latching Lock] to [Disable].

4. Select [Alarm Setup >>] quick key to enter [Alarm Setup] menu.

5. Select [Others] tab.

6. Set [Vtac Latching] as desired.

NOTE

 If the visual signal of lethal alarms is not latched, [Vtac Latching Lock] is not configurable and is automatically

set to [Enable].

7.10 Testing Alarms

When the monitor starts up, a self-test is performed. In this case the alarm lamp is lit in yellow and red respectively, and

the system gives a beep. This indicates that the visible and audible alarm indicators are functioning correctly.

For further testing of individual measurement alarms: perform the measurement on yourself (for example, SpO

2

or CO2)

or use a simulator. Then, adjust alarm limits and check that appropriate alarm behaviour is observed.

8 Monitoring ECG

8.1 Introduction

The electrocardiogram (ECG) measures the electrical activity of the heart and displays it on the monitor as a waveform

and a numeric. ECG monitoring provides the following algorithms:

 Advanced ECG algorithm

The Advanced ECG algorithm provides 3-, 5- and 12-lead ECG monitoring, ST-segment analysis, and extended

arrhythmia analysis.

 Mortara ECG algorithm

The Mortara ECG algorithm provides 3-, 5- and 12-lead ECG monitoring, ST-segment analysis, and arrhythmia

analysis.

 Glasgow algorithm

Glasgow algorithm provides an interpretation of the resting 12-lead ECG.

You can select algorithms at the time of purchase or as upgrades post sale:

 The equipment incorporating the Advanced ECG algorithm is labeled with an ST/ARR label.

 The equipment incorporating the Mortara ECG algorithm is labeled with the Mortara logo.

 The equipment incorporating the Glasgow algorithm is labeled with the Glasgow logo.

8.2 Safety

WARNING

 This equipment is not intended for direct cardiac application.

 Use only ECG electrodes and cables specified by Mindray.

 Make sure the conductive parts of electrodes and associated connectors for applied parts, including the

neutral electrode, should not contact any other conductive parts including earth.

 Periodically inspect the electrode application site to ensure skin quality. If the skin quality changes, replace

the electrodes or change the application site.

 Use defibrillation-proof ECG cables during defibrillation.

 Do not touch the patient or metal devices connected to the patient during defibrillation.

 To reduce the hazard of burns during high-frequency surgical procedure, ensure that the monitor’s cables

and transducers never come into contact with the electrosurgery unit (ESU).

 The neutral electrode of the HF surgical unit shall properly contact the patient. Otherwise, burns may result.

8-2 T1 Patient Monitor Operator’s Manual

CAUTION

 Interference from a non-grounded instrument near the patient and electrosurgery interference can cause

problems with the waveform.

NOTE

 After defibrillation, the screen display recovers within 10 seconds if the correct electrodes are used and

applied in accordance with the instructions for use.

8.3 Preparing to Monitor ECG

8.3.1 Preparing the Patient and Placing the Electrodes

To prepare the patient and place the electrodes:

1. Prepare the patient’s skin. Proper skin preparation is necessary for good signal quality at the electrode site, as the

skin is a poor conductor of electricity. To properly prepare the skin, choose flat areas and then follow this

procedure:

 Shave hair from skin at chosen sites.

 Gently rub skin surface at sites to remove dead skin cells.

 Thoroughly cleanse the site with a mild soap and water solution. We do not recommend using ether or pure

alcohol, because this dries the skin and increases the resistance.

 Dry the skin completely before applying the electrodes.

2. Attach the clips or snaps to the electrodes before placing them.

3. Place the electrodes on the patient.

4. Attach the electrode cable to the patient cable and then plug the patient cable into the ECG connector.

8.3.2 Choosing AHA or IEC Lead Placement

To choose AHA or IEC lead placement:

1. Select the ECG parameter window or waveform area to enter the [ECG Setup] menu.

2. Select [Others]→[Lead Set] and then select [3-lead], [5-lead], [12-lead] or [Auto] according to the applied

electrodes.

3. Select [Main Menu]→[Maintenance >>]→[User Maintenance >>]→enter the required password.

4. Select [Others >>]→[ECG Standard] and then select [AHA] or [IEC] according to the hospital standard.

T1 Patient Monitor Operator’s Manual 8-3

8.3.3 ECG Lead Placements

The electrode placement illustrations in this chapter adopt the AHA standard.

3-Leadwire Electrode Placement

Following is an electrode configuration when using 3 leadwires:

 RA placement: directly below the clavicle and near the right shoulder.

 LA placement: directly below the clavicle and near the left shoulder.

 LL placement: on the left lower abdomen.

5-Leadwire Electrode Placement

Following is an electrode configuration when using 5 leadwires:

 RA placement: directly below the clavicle and near the right shoulder.

 LA placement: directly below the clavicle and near the left shoulder.

 RL placement: on the right lower abdomen.

 LL placement: on the left lower abdomen.

 V placement: on the chest.

The chest (V) electrode can be placed on one of the following positions:

 V1 placement: on the fourth intercostal space at the right sternal border.

 V2 placement: on the fourth intercostal space at the left sternal border.

 V3 placement: midway between the V2 and V4 electrode positions.

 V4 placement: on the fifth intercostal space at the left midclavicular line.

 V5 placement: on the left anterior axillary line, horizontal with the V4

electrode position.

 V6 placement: on the left midaxillary line, horizontal with the V4

electrode position.

 V3R-V6R placement: on the right side of the chest in positions corresponding to those on the left.

 VE placement: over the xiphoid process.

 V7 placement: on posterior chest at the left posterior axillary line in the fifth intercostal space.

 V7R placement: on posterior chest at the right posterior axillary line in the fifth intercostal space.

8-4 T1 Patient Monitor Operator’s Manual

12-Leadwire Electrode Placement

12-lead ECG uses 10 electrodes, which are placed on the patient’s four limbs

and chest. The limb electrodes should be placed on the soft skin and the chest

electrodes placed according to the physician’s preference.

Lead Placement for Surgical Patients

The surgical site should be taken into consideration when placing electrodes

on a surgical patient. e.g. for open-chest surgery, the chest electrodes can be

placed on the lateral chest or back. To reduce artifacts and interference from

electrosurgical units, you can place the limb electrodes close to the shoulders

and lower abdomen and the chest electrodes on the left side of the mid-chest.

Do not place the electrodes on the upper arm. Otherwise, the ECG waveform

will be very small.

WARNING

 When using electrosurgical units (ESU), patient leads should be placed in a position that is equal distance

from the electrosurgery electrotome and the grounding plate to avoid burns to the patient. Never entangle

the ESU cable and the ECG cable together.

 When using electrosurgical units (ESU), never place ECG electrodes near to the grounding plate of the ESU,

as this can cause a lot of interference on the ECG signal.

8.3.4 Checking Paced Status

It is important to set the paced status correctly when you start monitoring ECG. The paced symbol is displayed

when the [Paced] is set to [Ye s ]. The pace pulse markers “|” are shown on the ECG wave when the patient has a paced

signal. If [Paced] is set to [No] or the patient’s paced status is not selected, the symbol

will be shown in the patient

information area.

To change the paced status, you can select either:

 the patient information area, or

 [Main Menu]→[Patient Setup]→[Patient Demographics], or,

 the ECG parameter window or waveform area→[Others >>],

and then, select [Paced] from the pop-up menu and then select [Ye s ] or [No].

If you do not set the paced status, the monitor issues a prompt tone when pace pulse is detected. At the same time, the

paced symbol flashes and the message [Please confirm the pace of patient] appears in the ECG waveform area. Then,

please check and set the paced status of the patient.

T1 Patient Monitor Operator’s Manual 8-5

WARNING

 For paced patients, you must set [Paced] to [Yes]. If it is incorrectly set to [No], the monitor could mistake a

pace pulse for a QRS and fail to alarm when the ECG signal is too weak.

 On ventricular paced patients, episodes of Ventricular Tachycardia may not always be detected.

 False low heart rate indicators or false Asystole calls may result with certain pacemakers because of

pacemaker artifact such as electrical overshoot of the pacemaker overlapping the true QRS complexes.

 Do not rely entirely upon the system’s automated arrhythmia detection algorithm. Keep pacemaker

patients under close surveillance.

 For non-paced patients, you must set [Paced] to [No].

 The auto pacer recognition function is not applicable to pediatric and neonatal patients.

8.4 Understanding the ECG Display

Your display may be configured to look slightly different.

1. Lead label of the displayed wave

2. ECG gain

3. ECG filter label

4. Notch filter status

Additionally, when a paced signal has been detected, the pace pulse marks “|” are shown on the ECG wave if the [Paced]

setting has been configured to [Ye s ].

8.5 Changing ECG Settings

8.5.1 Accessing ECG Menus

By selecting the ECG parameter window or waveform area, you can access the [ECG Setup] menu.

8.5.2 Setting Pacemaker Rate (For Mortara ECG Algorithm only)

Some pacemaker pulses can be difficult to reject. When this happens, the pulses are counted as a QRS complex and

could result in an incorrect HR and failure to detect some arrhythmias. You can set [Pacemaker Rate] to the pacemaker’s

rate in the [ECG Setup] menu. In this way, the monitor can calculate HR and detect arrhythmias more accurately. When

[Paced] is set to [No], the pacemaker rate cannot be set.

8.5.3 Choosing the Alarm Source

In most cases the HR and PR numerics are identical. In order to avoid simultaneous alarms on HR and PR, the monitor

uses either HR or PR as its active alarm source. To change the alarm source, select [Alm Source] in the [ECG Setup] menu

and then select either:

 [HR]: if you want the HR to be the alarm source for HR/PR.

 [PR]: if you want the PR to be the alarm source for HR/PR.

 [Auto]: If the [Alm Source] is set to [Auto], the monitor will use the heart rate from the ECG measurements as the

alarm source whenever a valid heart rate is available. If the heart rate becomes unavailable, for example the ECG

module is turned off or becomes disconnected, the monitor will automatically switch to PR as the alarm source.

8.5.4 Changing ECG Wave Settings

In the [ECG Setup] menu:

 You can select [ECG], [ECG1], or [ECG2] to select a lead to view. The ECG lead (s) selected is used for analysis (beat

detection, beat classification, and V-Fib detection). The waveform of selected lead should have the following

characteristics:

 The QRS should be either completely above or below the baseline and it should not be biphasic.

 The QRS should be tall and narrow.

 The P-waves and T-waves should be less than 0.2mV.

 If the wave is too small or clipped, you can change its size by selecting an appropriate [Gain] setting. If you select

[Auto] from [Gain], the monitor will automatically adjust the size of the ECG waves. In normal screen, only the

selected ECG wave can be adjusted. In other screens, all ECG waves can be adjusted simultaneously.

 You can change the wave sweep speed by selecting [Sweep] and then selecting the appropriate setting.

NOTE

 Changing the display gain on the monitor does not affect the amplitude of signal that is used by the

algorithm for beat detection.

T1 Patient Monitor Operator’s Manual 8-7

8.5.5 Changing the ECG Filter Settings

The ECG filter setting defines how ECG waves are smoothed. To change the filter setting, select [Filter] from [ECG Setup]

and then select the appropriate setting.

 [Mon]: Use under normal measurement conditions.

 [Diag]: Use when diagnostic quality is required. The unfiltered ECG wave is displayed so that changes such as

R-wave notching or discrete elevation or depression of the ST segment are visible.

 [Surg]: Use when the signal is distorted by high frequency or low frequency interference. High frequency

interference usually results in large amplitude spikes making the ECG signal look irregular. Low frequency

interference usually leads to wandering or rough baseline. In the operating room, the surgery filter reduces artifacts

and interference from electrosurgical units. Under normal measurement conditions, selecting [Surgery] may

suppress the QRS complexes too much and then interfere with ECG analysis.

 [ST]: Recommended when ST monitoring is used. The unfiltered ECG wave is displayed so that changes such as discrete

elevation or depression of the ST segment are visible.

CAUTION

 The [Diagnostic] filter is recommended when monitoring a patient in an environment with slight

interference only.

8.5.6 Setting the ECG Lead Set

You can set the [Lead Set] by selecting [ECG Setup]→[Others >>]. You can set the [Lead Set] as [Auto] if the auto lead

detection function is available.

8.5.7 Choosing an ECG Display Screen

When monitoring with a 5-lead or 12-lead set, you can select [Main Menu]→[Screens], or [Others>>]→[ECG Display]

in the [ECG Setup] menu to choose the screen type as:

 [Normal]: The ECG waveform area shows 2 ECG waveforms.

 [Full-Screen]: The whole waveform area shows 7 ECG waveforms only.

 [12-Lead]: The whole waveform ares displays 12 ECG waveforms (for 12-lead set only).

When monitoring with a 3-lead set, the screen type can only be set to [Normal].

When the screen type is set to [Normal], cascaded ECG waveforms can be displayed.

To cascade ECG waveforms:

1. Select the [Main Menu]→[Screens]→[Screen Setup].

2. Select [ECG1 Casc.] in the second row. A cascaded waveform is displayed in two waveform positions.

8-8 T1 Patient Monitor Operator’s Manual

8.5.8 Setting the Notch Filter

The notch filter removes the line frequency interference. Only when [Filter] is set to [Diagnostic], the [Notch Filter] is

adjustable.

To set the notch filter:

1. Select the ECG parameter window or waveform area to enter its setup menu. Then select [Others >>].

2. Set [Notch Filter] to:

 [Strong]: when waveform interference is strong (such as spikes).

 [Weak]: when waveform interference is weak.

 [Off]: to turn the notch filter off.

Set notch frequency according to the electric power frequency of your country. To set notch filter frequency:

1. When [Notch Filter] is turned on, select [Main Menu]→[Maintenance >>]→[User Maintenance >>]→enter the

required password.

2. Select [Others >>]→[Notch Freq.] and then select [50 Hz] or [60 Hz] according to the power line frequency.

8.5.9 Changing the Pacer Reject Settings

To change the pacer reject settings, select [ECG Setup]→[Others>>]→[Pacer Reject], and then select [On] or [Off].

 When [Paced] is set to [Yes]:

 When [Pacer Reject] is switched on, the pace pulses are not counted as extra QRS complexes.

 The pace pulse marks “|” are shown on the ECG wave when pace pulses are detected.

 When [Paced] is set to [No], the pace markers are not shown on the ECG wave, and the options of [Pacer Reject]

are inactivated.

8.5.10 Enabling Smart Lead Off

When the smart lead off function is enabled and there is a “lead off” in the lead of the first ECG wave, if another lead is

available, the monitor will automatically select the available lead. The system will re-calculate HR and analyze and detect

arrhythmia. When the “lead off” condition is corrected, the leads are automatically switched back.

To switch on/off the smart lead off function, select [Others >>] from the [ECG Setup] menu; select [Smart Lead Off] and

then select [On] or [Off] from the pop-up menu.

8.5.11 Setting the Alarm Level for ECG Lead Off Alarms

Select [Alarm Setup >>] from the [User Maintenance] menu. You can set [ECGLeadOff Lev.] from the pop-up menu.

measured value is available, the system adjusts the pitch tone of QRS sound based on the SpO2 value.

8.5.13 Adjusting the Minimum QRS Detection Threshold (For Advanced ECG Algorithm

Only)

To avoid false asystole alarms when the R wave amplitude is low and missed asystole alarms during ventricular standstill

(tall P waves, but no QRS), a means to manually adjust the minimum QRS detection threshold is provided.

To adjust the QRS threshold,

1. In the [ECG Setup] menu, set [Filter] to [Monitor].

2. Select [Others >>]→[Minimum QRS Threshold >>] to enter the [Minimum QRS Threshold] menu.

3. Select the up or down arrow to adjust the QRS threshold. Selecting [Default] resets the QRS threshold to the

default value (0.16 mV).

4. Select [Confirm] to make the changes effective.

CAUTION

 The setting of QRS threshold can affect the sensitivity of arrhythmia, ST, QT/QTc detection, and heart rate

calculation.

 If QRS amplitude is low, the monitor might not be able to calculate heart rate and false asystole may occur.

NOTE

 The minimum QRS detection threshold can only be adjusted when the ECG filter is set to [Monitor].

8.5.14 About the Defibrillator Synchronization

A synchronization pulse (100 ms, +5 V) is output through the multifunctional connector each time the monitor detects

an R-wave.

To use the defibrillator synchronization function, connect the monitor and the defibrillator with a synchronization cable.

WARNING

 Improper use of a defibrillator may cause injury to the patient. The user should determine whether to

perform defibrillation or not according to the patient’s condition.

8.6 About ST Monitoring

 Mortara ST segment analysis is not intended for neonatal patients.
 ST segment analysis calculates ST segment elevations and depressions for individual leads and then displays them

as numerics in the ST1 and ST2 areas.

 A positive value indicates ST segment elevation; a negative value indicates ST segment depression.
 Measurement unit of the ST segment deviation can be set to mV or mm. You can set the unit in the [Unit Setup]

menu from the [User Maintenance] menu.

 Measurement range of the ST segment deviation: -2.0 mV to +2.0 mV (-20.0 mm to +20.0 mm).

NOTE

 The monitor gives the message “Cannot Analyze ST” when the monitor cannot generate a valid ST value. In

this case, check the ECG signal quality and ST measurement points. If the message persists, check the
patient condition as per section 

, and decide whether to continue ST

monitoring.

 The ST algorithm has been tested for accuracy of the ST segment data. The significance of the ST segment

changes need to be determined by a clinician.
