Safety Information

Warnings

Warnings are identified by the WARNING symbol shown above.

W arnings alert the user to potential serious outcomes (death, injury, or adverse events) to the patient or user.

WARNING: The sensor extrapolates from the date and time provided by the N-595 when recording the sensor event record to the sensor. The accuracy of the date/time is the responsibility of the N-595. It is recommended that the N-595 user set the time/ date to the correct value before a sensor event record-enabled sensor is connected, and that this date/time not be changed while the sensor remains connected. Since a sensor with sensor event record data can be transported from one monitor to another, having discrepancies in the date/time between monitors and the sensor event record data will affect the order the sensor event record data appears. To eliminate this possible problem, all monitors within an institution should be set to the same time.

WARNING: Explosion hazard. Do not use the N-595 pulse oximeter in the presence of flammable anesthetics or gases.

WARNING: Chemicals from a broken LCD display panel are toxic when ingested. Use caution when handling a pulse oximeter with a broken display panel.

N-595 1

Safety Information

WARNING: Pulse oximetry readings and pulse signals can be affected by certain environmental conditions, O

XIMAX sensor

application errors, and certain patient conditions. See the appropriate sections of this manual for specific safety information.

WARNING: The use of accessories, sensor s, and cables other than those specified may result in increased emission and/or decreased immunity and inaccurate readings of the N-595 pulse oximeter.

WARNING: Failure to cover the OXIMAX sensor site with opaque material in high ambient light conditions may result in inaccurate measurements.

Cautions

Cautions are identified by the CAUTION symbol shown above.

Cautions alert the user to exercise care necessary for the safe and effective use of the N-595 pulse oximeter.

Safety Information

Caution: When connecting the N-595 to any instrument, verify proper operation before clinical use. Both the N-595 and the instrument connected to it must be connected to a grounded outlet. Accessory equipment connected to the pulse oximeter’s data interface must be certified according to IEC Standard 950 for data-processing equipment or IEC Standard 60601-1 for electromedical equipment. All combinations of equipment must be in compliance with IEC Standard 60601-1-1 systems requirements. Anyone who connects additional equipment to the signal input port or signal output port (N-595 data port connector) configures a medical system and is therefore responsible for ensuring that the system complies with the requirements of system standard IEC Standard 60601-1-1 and the electromagnetic compatibility system standard IEC S tandard 60601-1-2. The N-595 accuracy may degrade if it is connected to secondary I/O devices when the instrument is not connected to earth reference.

Caution: Federal law (U.S.A.) restricts this device to sale by or on the order of a physician.

Caution: Dispose of battery in accordance with local requirements and regulations.

The ADJUST UP button. Used to increase variable parameters of the monitor.

The ADJUST DOWN button. Used to decrease variable parameters in the monitor.

The CONTRAST button. Used in conjunction with the ADJUST UP and ADJUST DOWN buttons to lighten or darken the display screen.

The softkey buttons have multiple uses depending on the legend displayed above the button.

Description of Displays and Indicators

The type of display is user selectable. Refer to Selecting the Pleth View on page 34.

The pleth display includes a “wiper bar” plethysmographic waveform, menu bar, and current measured %SpO

2 and pulse rate. If

SatSeconds are enabled, the pleth display includes the SatSeconds indicator and SatSeconds setting. A decimal point after the %SpO

2 or

Description of Controls, Indicators, and Symbols

pulse rate indicate that the respective limits have been changed from the power on defaults (Monitor Trend Data on page 53).

The blip display includes a pulse amplitude blip bar, current measured %SpO

2 and pulse rate, and current upper and lower %SpO2 and pulse

rate limits. If SatSeconds are enabled, the blip display includes the SatSeconds indicator and SatSeconds setting. Decimal points after the %SpO

2 or pulse rate indicate that the respective limits have been

changed from the power-on defaults.

There are various matrixes within the O

XIMAX algorithm. Some of

these, are used to assess the severity of conditions presented to the N-595 in measuring SpO

2 and pulse rate on a patient. These

individual matrices or combinations of these matrices are used to drive the LED indicators on the N-595 front panel.

The OxiMax algorithm automatically extends the amount of data required for measuring SpO2 and pulse rate depending on the measurement conditions. During normal measurement conditions the averaging time is 6-7 seconds. During challenging measurement conditions which could be caused by low perfusion, motion, external interference like ambient light, or a combination of these, the OXIMAX algorithm automatically extends the amount of data required beyond 7 seconds. If the resulting dynamic averaging time exceeds 20 seconds, the pulse search indicator is lit solid and SpO2 and Pulse Rate will continue to be updated every second. As these conditions become even more challenging, the amount of data required continues to extend. If the dynamic averaging time reaches 40 seconds, the pulse search indicator begins flashing, the SpO2 and pulse rate displays flash zeros indicating a loss-of-pulse condition.

N-595 11

Description of Controls, Indicators, and Symbols

WARNING: Failure to cover the OXIMAX sensor site with opaque material in high ambient light conditions may result in inaccurate measurements.

The %SpO

2 Display. Shows the hemoglobin oxygen saturation level.

The display value flashes zeros during loss-of-pulse alarms and flashes the SpO

2 value when the SpO2 is outside the alarm limits.

During Pulse Search, the monitor continues to update the display. If alarm limits have been changed from their power-on defaults, a decimal point (.) is displayed after the SpO

2 value (81.).

The Pulse Amplitude Indicator (blip bar). Indicates pulse beat and shows the relative pulse amplitude. As the detected pulse becomes stronger, more bars light with each pulse. This indicator is available only in the blip view.

The Pulse Rate Display. Shows the pulse rate in beats per minute. It flashes during loss-of-pulse alarms and when the pulse rate is outside of the alarm limits. During Pulse Search, the monitor continues to update the display. Pulse rates outside of the pulse rate range (20 to 250 bpm) are displayed as the closest value within the range. If alarm limits have been changed from their power-on defaults, a decimal point (.) is displayed after the BPM value (112.).

The AC Power Indicator. Lights continuously when the N-595 is connected to AC power. It also indicates that the battery is charging. It is off when the monitor is being powered by internal battery.

The Low Battery Indicator. Lights continuously when 15 or fewer minutes of battery capacity remain. Flashes when the battery capacity reaches critical condition.

The Alarm Silence Indicator. Lights continuously when an audible alarm has been silenced. It flashes when the alarm silence duration has been set to Off.

The Motion Indicator. The motion indicator is lit whenever the O

XIMAX algorithm detects the presence of artifacts

its severity or the impact on the SpO

2 or pulse rate values. When the

independent of

motion indicator and the pulse search indicator are simultaneously lit, it is an indication that the artifact is significant and/or has been persistent.

The Pulse Search Indicator. Lights continuo usly prior to initial acquisition of a pulse signal and during prolonged and challenging monitoring conditions. The pulse search indicator flashes during a loss-of-pulse signal.

The Data In-Sensor Indicator. Lights to indicate that the attached

XIMAX sensor contains a patient sensor event record. The sensor

event record information may be viewed or printed.

The SatSeconds Indicator. Fills in clockwise as the SatSeconds alarm management system detects a %SpO setting. Empties in counterclockwise direction when %SpO

Setting up the Monitor

WARNING: To ensure patient safety, do not place the pulse oximeter in any position that might cause it to fall on the patient.

WARNING: As with all medical equipment, carefully route patient cabling to reduce the possibility of patient entanglement or strangulation.

WARNING: Ensure that the speaker is clear of any obstruction. Failure to do so could result in an inaudible alarm tone.

WARNING: Disconnect the N-595 and Nellcor OXIMAX se nsor from the patient during magnetic resonance imaging (MRI) scanning. Induced current could potentially cause burns.

WARNING: To ensure accurate performance and prevent device failure, do not subject the N-595 to extreme moisture, such as direct exposure to rain. Such exposure may cause inaccurate performance or device failure.

WARNING: Do not use an N-595 pulse oximeter, OXIMAX sensor, cables, or connectors that appear damaged.

WARNING: Do not lift the pulse oximeter by the pulse oxime try cable or power cord because the cable or cord could disconnect from the pulse oximeter, causing the pulse oximeter to drop on the patient.

Battery Operation

WARNING: Dispose of battery in accordance with local requirements and regulations.

Operating the N-595 on Battery Power

The N-595 monitor has an internal battery that can be used to power the monitor during transport or when AC power is not available. A new, fully charged battery will provide at least 2 hours of monitoring time under the following conditions:

• No audible alarms sound

• No analog or serial output devices are attached to the N-595

The monitor cannot operate with a fully discharged battery. Before attempting to turn on an N-595 monitor whose battery charge has been completely depleted, first plug the monitor into an AC outlet to allow the battery to charge for a few minutes. The monitor may then be powered on.

To charge a low or dead battery, connect the monitor to AC power. A full charge of a dead battery takes 14 hours while the monitor is turned off. A full charge of a dead battery takes 18 hours while the monitor is in operation (monitoring a patient).

When all of the following conditions are present for 15 minutes, the N-595 will automatically shut down:

• Monitor is running on battery power

• No buttons have been pressed

N-595 21

Battery Operation

Note: Whenever the monitor is connected to AC power, the battery is

Low Battery Indicator

The Low Battery Indicator lights and a low priority alarm begins to sound when approximately 15 minutes of monitoring time is available on the existing battery charge. Refer to Table 2 for a description of the low and critical battery conditions.

• No pulse has been detected (for example, when a patient is not connected to the O

XIMAX sensor or the OXIMAX

sensor is disconnected from the monitor)

• No alarms are present (other than low battery or a non-correctable error)

being charged. Therefore, it is recommended that the monitor remain connected to AC power when not in use. This will ensure a fully charged battery whenever it is needed.

If the monitor is not on AC power, a low battery audible alarm can be canceled by pressing the ALARM SILENCE button. The low battery indicator and display screen message will continue to be displayed. Plugging the monitor into AC power will silence the audible alarm, but the low battery indicator will stay lit as long as the battery is in the low voltage condition. After the 15-minute period of low battery condition, a high priority alarm will sound for about 10 seconds before the monitor shuts off.

If the monitor backlight is turned off during a low battery condition, the backlight cannot be turned back on.

It is recommended that qualified service personnel replace the internal battery every 24 months. Replaced batteries should be disposed of in accordance with local ordinances.

Battery Operation

Caution: If the N-595 pulse oximeter is to be stored for a period of 3 months or longer , notify service personnel to r emove the battery from the pulse oximeter prior to storage. Recharge the battery when the battery has not been charged for 2 or more months.

Caution: The pulse oximeter default settings will return to factory default setting if the battery becomes fully discharged or is replaced. Qualified service personnel will have to reset the institutional defaults, following the instructions in the service manual.

Note: If the AC voltage selector switch on the monitor rear panel

does not match your AC voltage source, the monitor may run on battery power, even though it is plugged into AC power, which will eventually result in a low priority alarm and a lighted low battery indicator. Ensure that the switch setting matches your AC voltage.

Note: As the battery is used and recharged over a period of time, the

amount of time between the onset of the low battery alarm and the instrument shut-off may become shorter.

Turning On the Monitor

Before using the N-595 in a clinical setting, you must verify that the monitor is working properly and is safe to use. Proper working condition will be verified each time the N-595 is turned on as described in the following procedure.

Caution: If any indicator or display element does not light when the pulse oximeter is turned on, do not use the pulse oximeter. Instead, contact qualified service personnel, your local Nellcor representative, or Nellcor’s Technical Services Department.

N-595 29

Using the Monitor

Note: Physiological conditions, medical procedures, or external

agents that may interfere with the monitor’s ability to detect and display measurements, include dysfunctional hemoglobin, arterial dyes, low perfusion, dark pigment, and externally applied coloring agents such as nail polish, dye, or pigmented cream.

Note: The monitor automatically starts the Power-On Self-Test

(POST), which tests the monitor circuitry and functions.

Caution: During POST (immediately after power-up), confirm that all indicators light, all display segments turn on, and the pulse oximeter speaker sounds a one-second tone.

1. Turn on the N-595 by pressing the ON/STANDBY button.

2. Ensure that all of the front panel indicators illuminate.

3. Once the display test portion of POST is complete, the N-595 software version is displayed for approximately 5 seconds.

Note: The software version shown above is only a sample. Check

your monitor for the software version installed.

Software version numbers are often needed when calling Nellcor’s Technical Services Department or your local Nellcor representative for technical assistance. Write down the software version number and have it available prior to requesting technical assistance.

Using the Monitor

4. If the N-595 detects an internal problem during POST, an error

tone sounds and the monitor displays an error code (EEE) and the corresponding number (see Troubleshooting on page 117).

5. Upon successful completion of the POST, the N-595 sounds a

one-second tone indicating that the monitor has passed the test.

WARNING: If you do not hear the POST pass tone, do not use the pulse oximeter.

WARNING: Ensure that the speaker is clear of any obstructions. Failure to do so could result in an inaudible alarm tone.

Note: In addition to serving as the POST pass verification, the POST

pass tone also functions as an audible confirmation that the speaker is performing properly. If the speaker does not function, the alarm warning sounds cannot be heard.

OXIMAX Sensor Attached

When an OXIMAX sensor is attached to the monitor, a “DAT A TYPE: . . .” message is displayed briefly at the bottom of the monitor display. For a sensor containing data, the message identifies the sensor data type, For a blank sensor, the message identifies the monitor’s current

Using the Monitor

data type setting that will be used to write data to the sensor. The data type settings are SPO2 and SPO2+BPM.

Note: The type of data recorded is only displayed when data is resent

in the O

XIMAX sensor.

The monitor displays zeros in the %SpO

2 and Pulse Rate displays

while the N-595 is searching for a valid pulse. For optimal performance, allow the monitor to search and lock onto a pulse for approximately 10 seconds in non-motion conditions.

When a valid pulse is detected, the monitor enters the Monitoring Mode and displays patient parameters.

Look for movement of the blip bar or of the plethysmographic waveform indicating that the monitor is displaying real-time data. Listen for the pulse beep tone. If the pulse beep tone does not sound with each pulse, it is an indication that the pulse beep volume is set to zero, the speaker is malfunctioning, or the signal is corrupted.

When an O

XIMAX sensor is attached to the monitor and is applied to a

patient, if the monitor loses the pulse signal, the monitor will display “--- & ---” (3 dashes and 3 dashes) and remain in Pulse Search Mode for 5 seconds before displaying the poor signal condition screen. The poor signal condition screen is part of the N-595's Sensor Messages

feature. For more information about OXIMAX Sensor Messages, refer OXIMAX Sensor Messages on page 49.

No OXIMAX Sensor Attached

Upon successful completion of the POST, the N-595 monitor sounds a one-second tone indicating that the monitor has passed POST.

Using the Monitor

The monitor displays dashes (---) and the Pulse Search indicator is not lit, indicating that the monitor failed to detect an O

Trend data is further explained in Specifications on page 147.

Trend data information may be retrieved through the N-595 data port or cleared using options available in a display menu.

Caution: Monitor trend data will be lost if the main battery fails or is removed.

Trend Data Operation

Whenever the N-595 is turned on, it stores the monitor %SpO2 and pulse rate readings in memory every 2 or 4 seconds (regardless of whether the N-595 is monitoring a patient or not). The N-595 can store up to 48 hours of 4-second trend data or 24 hours of 2-second trend data. The 48/24 hours of stored trend data are available for downloading to a printer or a portable computer . Up to 50 alarm limit changes can be stored in the trend data. If more than 50 alarm limit changes occur during the 48/24 hours of trend data collection, the additional alarm limit changes will take space reserved for trend data.

Caution: Changing alarm limit settings uses up trend memory space. Change alarm limits only as needed.

Note: Trend memory always contains the most recent 48 hours of

Monitor Trend

data, with newly collected data overwriting the oldest data on a rolling basis. The N-595 continues to record data points as long as the monitor is powered on, with “blank” data points collected if no O

XIMAX sensor is connected to the monitor or

patient. “Blank” data will over-write older patient data if the memory becomes full. Therefore, if you want to save old patient data, it is important that you turn your monitor of f when you are not monitoring a patient, and that you download the trend memory before it fills up and over-writes the old data with new data (or “blank” data).
