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 ) indicator flashes. Patient perfusion signals are graded as good, marginal, or detected pulse, the perfusion ( indicator flashing green, yellow, or red, respectively. This simple inadequate and are indicated by the 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.

Visual Indicators SpO2 Display

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 SpO2 data. The perfusion indicator may blink one of three colors: green, yellow, or red: • Red indicates the pulse amplitude is too small. During red perfusion, SpO2 and pulse rate values are not updated. After twenty seconds, the values are replaced with dashes indicating SpO2 measurement is not possible. • Yellow indicates the pulse waveform amplitude is marginal or the pulse oximeter has detected artifact. Although SpO2 data 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 SpO2 data is accurate. (Audible Alarm Inactive) Indicator

• The • The

indicator continuously illuminated indicates audible alarms are permanently disabled. 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 SENSOR 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 SENSOR 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.

16

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 (800) 356-8874 or (763) 553-9968.

CAUTION! Inaccurate SpO2 and/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. SpO2 Display

If the patient's SpO2 is equal to or goes beyond the set limits, the SpO2 display flashes at once per second until alarm condition concludes. ♥ and SpO2 Display If both the SpO2 and ♥ displays flash at once per second, both the pulse rate and SpO2 values are equal to or go beyond the set limits.

17

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).
