Introduction
Indications For Use
The 8600 Pulse Oximeter is intended to be used to monitor oxygen saturation and pulse rate for adult,
pediatric, and neonatal patients in hospital, ambulatory, and EMS environments.
General
The 8600 Pulse Oximeter is small, light weight, and is intended to be portable. It has audible and visual alarms
for monitoring patient status. The 8600 may be connected to A/C power or run from its internal battery. It
typically operates for 30 hours on a fully charged battery. The 8600 requires no routine calibration or
maintenance.
The 8600 determines arterial oxyhemoglobin saturation (SpO2) by measuring the absorption of red and
infrared light passed through tissue. Changes in absorption caused by pulsation of blood in the vascular bed
are used to determine arterial saturation and pulse rate.
Oxygen saturation and pulse rate are displayed on light emitting diode (LED) digital displays. On each
detected pulse, the perfusion ( ) indicator flashes. Patient perfusion signals are graded as good, marginal, or
inadequate and are indicated by the indicator flashing green, yellow, or red, respectively. This simple
method gives the user a pulse-by-pulse visual indication of waveform signal quality without requiring the user
to perform complex waveform analysis during critical patient care situations.
Sensor disconnect or malfunction is indicated by lack of good perfusion flashes and/or the red SENSOR
indicator on the front panel illuminating. Ultimately, if adequate perfusion pulses are not received, the SpO2
and pulse rate numerical values will be replaced by dashes.
The 8600 Pulse Oximeter has been approved by the U.S. Air Force for use in the U.S.A.F. aeromedical
evacuation environment when operating on its internal battery or with the NONIN Model 7708 A/C Battery
Charger.

Operating Instructions
Battery Charging
If portable operation is not necessary, continuously charging with the proper battery charger is recommended.
The battery charger plugs into the back of the 8600 where it is marked "BATTERY CHARGER". Refer to
Figure II for illustration. This will assure a fully charged battery should portable operation be required.
The battery charger requires 15 hours to recharge a completely depleted battery pack. While the battery
charger is connected to AC power, the green indicator will be illuminated, and the pulse oximeter may be
operated during this time if the red indicator is not illuminated when the unit is turned on. If the red
indicator is illuminated when the unit is turned on, the battery must charge until the red is no longer
illuminated before it may be used.
The battery pack in the 8600 will typically power the unit for 30 hours with a full charge without needing to be
charged.
The 8600 indicates when the battery is low by illuminating the indicator in red.
NOTE: The Nonin Model 7708 Battery Charger must be used in place of other NONIN battery
chargers to meet U.S. Air Force requirements for the U.S.A.F. aeromedical evacuation
environment
Connecting the Cable and Sensors
Connect the patient interface cable (Model 8800I) to the 8-pin female latching connector on the front of the
8600 shown in Figure I. Connect the sensor to the patient interface cable. Position the appropriate sensor on
the patient. If additional cable length is necessary, connect the Model 8604X-10, -20, or -30 Extension Cable or
the Model 8500I Patient Extension Cable between the sensor and the 8800I.
Turning On The Pulse Oximeter
Turn on the 8600 by pressing the " I" power switch on the front of the pulse oximeter. Refer to Figure I.
When the 8600 is turned on, the displays will cycle through the following sequence before displaying valid data:
• "" (8600) or " " (8600M)
• current time in hours and minutes saved in memory
• software revision number
• ""
• SELF

Verifying Operation
CAUTION! The 8600 must be able to measure the pulse properly to obtain accurate SpO2
measurement. Verify that nothing is hindering the pulse measurement before relying
on the SpO2measurement.
Verify that the sensor is properly positioned. Ensure the system is sensing adequate perfusion by observing
that the indicator is blinking green and correlates to the pulse rate for 10 seconds. Should the perfusion
light be red or yellow or flashing erratically, reposition the sensor or try a different sensor.
For the first 2 minutes of operation, the indicator will flash to indicate the audible alarm is temporarily
disabled during power on. During the first two minutes, the audible alarm may be enabled by pressing the
AUDIO button. If the audible alarm is not permanently disabled, the indicator will not be illuminated after
the first 2 minutes of operation and the audible alarm will be enabled.
If the alarm is permanently disabled, the indicator will illuminate continuously, and pressing the AUDIO
button will not have no effect on the audible alarm.
Cleaning the Pulse Oximeter
CAUTION! Do not immerse the 8600 in liquid, and do not use caustic or abrasive cleaning
agents.
The 8600 Pulse Oximeter may be cleaned with a mild detergent and a soft cloth or with an isopropyl alcohol
wipe. Allow enough time for the 8600 to dry thoroughly before reusing.

Visual Indicators
SpO2Display
The upper digital display is a 3-digit light emitting diode (LED) digital display that displays oxygen saturation
percentage.
♥(Pulse Rate) Display
The lower digital display is a 3-digit LED digital display that displays pulse rate in pulses per minute.
(Perfusion) Indicator
The perfusion indicator (identified by the waveform symbol ) will flash once for each pulse while
measuring oxygen saturation. The perfusion indicator changes color to indicate changes in the pulse waveform
signal that may affect the SpO2data.
The perfusion indicator may blink one of three colors: green, yellow, or red:
• Red indicates the pulse amplitude is too small. During red perfusion, SpO2and pulse rate values are not
updated. After twenty seconds, the values are replaced with dashes indicating SpO2measurement is not
possible.
• Yellow indicates the pulse waveform amplitude is marginal or the pulse oximeter has detected artifact.
Although SpO2data is acceptable, corrective measures should be considered to improve sensor
placement, change sensor type, or reduce patient movement. After 90 seconds of yellow perfusion, the
8600 will go into sensor alarm mode.
• Green indicates the pulse waveform signal is of good quality and SpO2data is accurate.
(Audible Alarm Inactive) Indicator
• The indicator continuously illuminated indicates audible alarms are permanently disabled.
• The indicator flashes at once a second when the audible alarms are temporarily disabled.
This indicator is a yellow indicator that flashes when the audible alarm is temporarily disabled. The
indicator will illuminate continuously if the audible alarm has been permanently disabled via option switch 1
and the alarm volume OFF.
SENSOR Indicator
The SENSO
R
indicator continuously illuminated indicates there is a sensor alarm. This is caused by the system
determining that the sensor is disconnected, damaged, or dislodged. When a sensor fault is found, the red
SENSO
R
indicator illuminates and the audible alarm sounds continuously until the condition terminates.
If a sensor alarm condition persists for 10 seconds or longer the displays will show dashes (---). From the
beginning of the sensor alarm condition up to the time that the displays go into the dash mode, the numerical
values will freeze on the last valid values. The displays display new, valid data after three discernible pulses
have been found.

17
SELF
TEST Indicator
The self test function is active whenever the unit is powered on. If a self test fault is found, the SELF
TEST indicator
illuminates and the audible alarm sounds continuously. This condition can only be cleared by turning the 8600
to STBY ( O) and then back ON ( I). This alarm cannot be shut off with the alarm volume control or by
pressing the AUDIO button.
NOTE: If this condition cannot be cleared, do not use the pulse oximeter. Contact Nonin
Customer Support at [phone] or [phone].
(Low Battery) Indicator
CAUTION! Inaccurate SpO2and/or pulse rate measurement may result if the 8600 is operated in a
low battery condition.
The indicator will illuminate in red if the battery voltage becomes low and the battery needs to be
recharged. Fully charged batteries will typically power the 8600 for 30 hours. Charging depleted batteries will
require 15 hours to fully recharge, but the pulse oximeter may be used if only partially recharged as long as the
indicator is not illuminated.
NOTE: Setting the month to “00” disables the clock function and helps conserve battery life.
(Battery Charging) Indicator
When the indicator is illuminated in green, the 8600 is connected to AC power and the battery is charging.
To recharge a fully depleted battery, the 8600 must be connected to AC power for 15 hours.
If the indicator is not illuminated, the 8600 is operating from the battery (AC power is not connected).
Flashing Displays
♥ Display
If the patient's pulse rate is equal to or goes beyond the set limits, the ♥display flashes at once per second until
alarm condition concludes.
SpO2Display
If the patient's SpO2is equal to or goes beyond the set limits, the SpO2display flashes at once per second until
alarm condition concludes.
♥ and SpO2Display
If both the SpO2and ♥displays flash at once per second, both the pulse rate and SpO2values are equal to or
go beyond the set limits.

18
Audible Indicators
CAUTION! The audible alarm of the 8600 is for the convenience of the attendant near the patient.
It is not intended to call an attendant from another room or from a distance. The user
must determine the audible distance based on the operating environment.
Audible Alarm
• During normal operation, rotating the dial counter-clockwise until it clicks will turn the audible
alarm OFF if option switch 1 is in the up position. If option switch 1 is in the down position, turning the
audible alarm OFF will have no effect.
• During normal operation, pressing the AUDIO button disables the audible alarm for 2 minutes.
• Pressing the AUDIO button during the 2-minute disabled period immediately enables the audible alarm.
• The audible alarm sounds once per second for all patient alarms.
• The audible alarm sounds steadily for a sensor alarm.
The audible alarm is adjustable from OFF to 80 db(A).
Audible Pulse Tone
• During normal operation, rotating the dial counter-clockwise until it clicks will turn the audible
pulse tone OFF.
• When enabled, the 8600 will sound a tick once for each heart beat.
• The tone varies in pitch with the SpO2level. As the SpO2level decreases, the pitch of the pulse tone
decreases. If the 8600 loses the pulse, the audible pulse tone will beep at a much higher pitch.
The audible pulse tone volume may be varied from OFF to 70 db(A).

Real-Time Data Output
Both the 8600 and 8600M Pulse Oximeters provide real-time output capability to a custom printer via the 15-
pin Sub-D connector labeled as “RECORDING OUTPUT” on the rear of the 8600 (refer to Figure 2).
The information from the 8600/8600M in the real-time mode is sent in an ASCII serial format at 9600 baud
with 9 data bits, 1 start bit, and 1 stop bit. The data is output at a rate of once per second.
NOTE: In real-time mode, the 9th data bit is always set to the mark condition. Therefore the
real-time data may be read as 8 data bits, no parity.
During data output, the indicator displays the status of the data transfer.

Status Indicator During Data Transfer
Real-time data is printed in the following format:
HH:MM:SS SPO2=XXX HR=YYY
where “HH” represents the hour the real-time clock is set to, “MM” represents the minutes, “SS” represents
the seconds, “XXX” represents the SpO2value, and “YYY” represents the heart rate. The SpO2and heart rate
will be displayed as “---” if there is no data available for the data reading.
NOTE: Pressing the
AUDIO button during real-time printing will force a line to be printed (touch
print).
