Safety Information

Warnings

Warnings are identified by the WARNING symbol shown above.

Warnings 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-600 when recording the sensor event record to the sensor. The accuracy of the date/time is the responsibility of the N-600. It is recommended that the N-600 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-600 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.

OxiMax N-600 1

Safety Information

WARNING: Pulse oximetry readings and pulse signals can be affected by certain environmental conditions, OxiMax sensor application errors, and certain patient conditions. See the appropriate sections of this manual for specific safety information.

WARNING: The use of accessories, sensors, and cables other than those specified may result in increased emission and/or decreased immunity and inaccurate readings of the N-600 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-600 pulse oximeter.

Page 13

Safety Information

Caution: When connecting the N-600 to any instrument, verify proper operation before clinical use. Both the N-600 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-600 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 Standard 60601-1-2. The N-600 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.

Description of Displays and Indicators

The type of display is user selectable. Refer to Selecting the Pleth View on page 40.

Page 21

Description of Controls, Indicators, and Symbols

The pleth display includes a “wiper bar” plethysmographic waveform, menu bar, and current measured %SpO SatSeconds are enabled, the pleth display includes the Indicator and SatSeconds setting. A decimal point after the %SpO

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 matrices within the N-600 algorithm. Some of these, are used to assess the severity of conditions presented to the N-600 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-600 front panel.

The advanced signal processing in the N-600 algorithm automatically extends the amount of data required for measuring SpO

2 and pulse

rate depending on the measurement conditions. During normal measurement conditions the averaging time is six seconds to seven seconds (approximately three seconds in Fast Mode). During conditions such as those caused by low perfusion, interference (e.g., external interference like ambient light), or a combination of the two, the N-600 algorithm automatically extends the amount of data required beyond the minimum as set by the response mode. See Setting the N-600 Response Mode on page 53. If the resulting dynamic averaging time exceeds 20 seconds, the indicator is lit solid and SpO

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 N-600 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-600 is

connected to AC power. It also indicates that the battery is charging. It is off when the N-600 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.

Page 23

Description of Controls, Indicators, and Symbols

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

Interference Indicator. The Interference Indicator lights

whenever the N-600 algorithm detects that the incoming signal

quality is degraded

An intermittently lit

Interference Indicator is common during

patient monitoring, and indicates the N-600 algorithm is dynamically adjusting the amount of data required for measuring SpO

2 and Pulse

Rate. When lit continuously, it indicates the N-600 algorithm has extended the amount of data required for measuring SpO

2 and Pulse

Rate and, consequently, fidelity in tracking rapid changes in these values may be reduced (see Description of Displays and Indicators on page 10).

The

Pulse Search Indicator. Lights continuously 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

OxiMax 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 limit setting. Empties in counterclockwise direction when %SpO

2 reading outside of the

reading is within limits. When the indicator is full, a medium priority alarm will sound.

The

Fast Response Mode Indicator. The response mode setting

dictates the response time (two-seconds to four-seconds in fast mode and four-seconds to seven-seconds in normal mode) applied by the N- 600 algorithm in its calculation of SpO

Degradations can be caused by ambient light, electrical noise, electro-surgical interference, patient activity, or other causes.

WARNING: The N-600 is not defibrillator-proof. However, it may remain attached to the patient during defibrillation or while an electrosurgical unit is in use, but the readings may be inaccurate during the defibrillation and shortly thereafter.

WARNING: In the USA, do not connect the pulse oximeter to an electrical outlet controlled by a wall switch, because the pulse oximeter may be accidentally turned off.

WARNING: Use only the Nellcor pulse oximetry cable DOC-10 with the N-600 pulse oximeter. Use of another pulse oximetry cable will have an adverse effect on performance. Do not attach any cable that is intended for computer use to the OxiMax sensor port. Do not connect any device other than a Nellcor-approved OxiMax sensor to the OxiMax sensor connector.

WARNING: The N-600 should not be used adjacent to or stacked with other equipment. If adjacent or stacked use is necessary, the N-600 should be observed to verify normal operation in the configuration it is to be used.

Battery Operation

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

Operating the N-600 on Battery Power

The N-600 has an internal battery that can be used to power the N-600 during transport or when AC power is not available. A new, fully charged battery will provide at least two hours of monitoring time under the following conditions:

• No audible alarms sound

• No analog or serial output devices are attached to the N-600

The N-600 cannot operate with a fully discharged battery. Before attempting to turn on an N-600 whose battery charge has been completely depleted, first plug the N-600 into an AC outlet to allow the battery to charge for a few minutes. The N-600 may then be powered on.

To charge a low or dead battery, connect the N-600 to AC power. A full charge of a dead battery takes 14 hours while the N-600 is turned off. A full charge of a dead battery takes 18 hours while the N-600 is in operation (monitoring a patient).

When all of the following conditions are present for 15 minutes, the N-600 will automatically shut down:

• N-600 is running on battery power

• No buttons have been pressed

Note: Whenever the N-600 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 OxiMax sensor or the OxiMax sensor is disconnected from the N-600)

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

being charged. Therefore, it is recommended that the N-600 remain connected to AC power when not in use. This will ensure a fully charged battery whenever it is needed.

If the N-600 is not on AC power, a low battery audible alarm can be canceled by pressing the Indicator and display screen message will continue to be displayed. Plugging the N-600 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 N-600 shuts off.

If the N-600 backlight is turned off during a low battery condition, the backlight cannot be turned back on until the low battery condition is corrected.

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-600 pulse oximeter is to be stored for a period of three months or longer, notify service personnel to remove the battery from the pulse oximeter prior to storage. Recharge the battery when the battery has not been charged for two 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 N-600 Service Manual.

Note: If the AC voltage selector switch on the N-600 rear panel does

not match your AC voltage source, the N-600 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

Battery

Indicator. Ensure that the switch setting matches your

Low

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 N-600 shut-off may become shorter

Turning On the N-600

Before using the N-600 in a clinical setting, you must verify that the N-600 is working properly and is safe to use. Proper working condition will be verified each time the N-600 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 Customer Services Department.

Note: Physiological conditions, medical procedures, or external

agents that may interfere with the N-600’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 N-600 automatically starts the Power-On Self-Test

(POST), which tests the N-600 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-600 by pressing the

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

On/standby button.

Page 45

Using the N-600

3. Once the display test portion of POST is complete, the N-600 software version is displayed for approximately five seconds.

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

your N-600 for the software version installed.

Software version numbers are often needed when calling Nellcor’s Customer 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.

4. If the N-600 detects an internal problem during POST, an error tone sounds and the N-600 displays an error code (EEE) and the corresponding number. See Troubleshooting on page 123.

5. Upon successful completion of the POST, the N-600 sounds a one-second tone indicating that the N-600 has passed the test.

OxiMax N-600 35

Page 46

Using the N-600

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

OxiMax Sensor Attached

When an OxiMax sensor is attached to the N-600, a “DATA TYPE: . . .” message is displayed briefly at the bottom of the N-600 display. For a sensor containing data, the message identifies the sensor data type. For a blank sensor, the message identifies the N-600’s current data type setting that will be used to write data to the sensor. The data type settings are SPO2 and SPO2+BPM.

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.

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

present in the OxiMax sensor.

The N-600 displays zeros in the %SpO

2 and Pulse Rate displays

while the N-600 is searching for a valid pulse. For optimal performance, allow the N-600 to search and lock onto a pulse for approximately 10 seconds in non-interference conditions.

Page 47

Using the N-600

When a valid pulse is detected, the N-600 enters the Monitoring Mode and displays patient parameters.

Look for movement of the blip bar or of the plethysmographic waveform indicating that the N-600 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 OxiMax sensor is attached to the N-600 and is applied to a patient, if the N-600 loses the pulse signal, the N-600 will display “---

& ---” (three dashes and three dashes) and remain in Pulse Search Mode for five seconds before displaying the poor signal condition screen. The poor signal condition screen is part of the N-600's Sensor Messages feature. For more information about OxiMax Sensor Messages, refer OxiMax Sensor Messages on page 56.

N-600 Trend

The N-600 stores up to 48 hours of four-second trend data or 24 hours of two-second trend data. The amount of trend data displayed on the screen is determined by using the

ZOOM softkey. The settings

available are 20 and 40 seconds, 15 or 30 minutes, and 1, 2, 4, 8, 12, 24, 36, or 48 hours. All trend data are displayed in a graphical format except the 20- and 40-second trend displays, which are shown in tabular format.

The trend display is scrolled, that is, the data displayed can be moved throughout the 48 hours of trend data. Selecting the one-hour trend display allows you to view one hour of trend information. By using the scrolling feature, any one hour of trend data can be viewed over the 48 hours of trend information. The the display to the left and the

When the data are displayed, the most recent readings are on the right side of the graph. The numbers below %SpO

2 indicate the highest and

lowest parameter values at the cursor position (vertical dotted line on the display). See Table 4 on page 64.

Trend data information may be retrieved through the N-600 data port or cleared using options available in a display menu.

Caution: N-600 trend data will be lost if the main battery fails or is removed.

Page 71

Trend Data Operation

While the N-600 is turned on, it stores the N-600 %SpO2 and pulse rate readings in memory every two seconds (fast response mode) or four seconds (normal response mode), regardless of whether the N-600 is monitoring a patient or not. The N-600 can store up to 48 hours of trend data in the normal response mode or 24 hours of trend data in the fast response mode. 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, then the additional alarm limit changes take the space reserved for trend data.

Caution: Change alarm limits only as needed.

Trend memory always contains the most recent 48 or 24 hours of data, with newly collected data overwriting the oldest data on a preemptive basis. The N-600 continues to record data points as long as the N-600 is turned on. Blank data points are collected when the N-600 is not connected to a patient. Blank data overwrites older patient data if the memory becomes full. Therefore, to retain old patient data, it is important to turn off your N-600 when you are not monitoring a patient. Download the trend memory before it fills up and overwrites the old data with new or blank data. Figure 3 illustrates when the new trend data starts to overwrite the old trend data.

OxiMax Sensor Event Record

The adhesive OxiMax sensors are capable of storing patient event data. A sensor event record allows alarm event history to travel with the patient on the sensor’s memory chip for quick assessment at every point of care where OxiMax monitors are used.

Patient (event) data is stored on the memory chip of adhesive OxiMax sensors (single-patient-use OxiMax sensors only). The event data is stored (recorded) with the limit/threshold settings that were active at the time of the event on the recording monitor. These events can be viewed on the next OxiMax sensor monitor when the patient moves to a new point of care.

An event occurs when the %SpO lower alarm limit for at least 15 seconds. The first OxiMax sensor event record event will be stored in the OxiMax sensor after the OxiMax sensor has been attached to a patient for five minutes and every five minutes thereafter. The maximum number of events that can be stored in an OxiMax sensor is 100.

2 value exceeds either the upper or

Page 82

OxiMax Sensor Event Record

Event records can only be viewed after an OxiMax sensor containing patient data (event records) has been connected to an OxiMax monitor. Event records are designed to view patient events from prior areas of care or transport (history) while monitor trend should be used to view data or events from a patient currently being monitored. The monitor’s SENSOR EVENT RECORD Indicator will light when an OxiMax sensor containing event data is connected to the OxiMax monitor.

Patient event data is accessed by pressing the main menu and selecting the record can be viewed in graphical form ( table (

Note: Once the OxiMax sensor event record type is set up in the

OxiMax sensor and event data is stored in the OxiMax sensor,

the OxiMax sensor event record type cannot be reset. The monitor’s type set up can be changed at any time.

Recording and viewing of OxiMax sensor event record is only available on OxiMax compatable monitors. The OxiMax sensors may function on older technology monitors but the OxiMax sensor event record feature is not available.

OxiMax Sensor Event Record Graphical Data

Graphical representations of patient event history is only available on single-patient-use OxiMax sensors. Graphed data points are the minimum or maximum %SpO throughout the duration of an event (%SpO alarm threshold for at least 15 seconds) and continuing every 30 seconds until the actual %SpO threshold.

The duration of an event is determined by the number of data points in the event. Each data point is stored at 30-second intervals.

Events end for one of four reasons:

The type of data displayed in the graph is indicated to the left of the vertical axis (%SpO

2). Below this is the range of values (min/max)

during the event. The duration of the event is shown below the range value. The vertical axis of the graph is labeled to show the magnitude scale of the graphed data. The horizontal axis is not labeled but automatically scales to accommodate the number of 30-second intervals during the event. The alarm threshold (lower than %SpO

alarm limit) is represented by a horizontal dotted line across the graph. The first data point is always the alarm threshold.

Events are displayed one at a time, one per graph. Graphs are displayed in chronological sequence with the most recent event shown first when accessing the graphical OxiMax sensor event display. The user can move between events by using the two left-most softkeys which are labeled with left- and right-facing arrow icons, respectively.
