Displays and Indicators
Displays and Indicators
SpO2Display
The SpO2display is the upper numeric display (identified by the %SpO2symbol). This 3-digit
light-emitting diode (LED) display shows the current oxygen saturation percentage. This display
flashes for SpO2alarms.
Pulse Rate Display
The Pulse Rate display is the lower numeric display (identified by the symbol). This 3-digit
LED display shows the pulse rate in pulses per minute. This display flashes for Pulse Rate alarms.
Pulse Quality Display
The Pulse Quality display (identified by the symbol) is a tricolor LED that blinks once for each
detected pulse. The Pulse Quality display changes color to indicate changes in the pulse
waveform signal that may affect the SpO2data. It may blink green, amber or red.
•Green indicates a good pulse strength
•Amber indicates a marginal pulse strength. To improve signal quality, reposition the
sensor, try a different sensor type, eliminate patient movement, or improve the site’s
circulation.
•Red indicates an inadequate pulse strength. While the Pulse Quality display is red, SpO2
and pulse rate values are not updated. After about 10 seconds, the values are replaced
with dashes, indicating that readings are not possible.
Low Battery Indicator
Low and critically low battery capacity is indicated with a flashing Low Battery indicator and a
medium priority alarm. When batteries are critically low, the digital displays will go blank, and the
Pulse Quality display will blink amber or red, but not green. Any SpO2or pulse rate alarms in effect
when critically low battery capacity is reached will be latched, and flashing dashes will appear on
the corresponding display. After 10 minutes at critically low battery capacity, the pulse oximeter will
shut off automatically.
Sensor Fault Display
If the device determines that a sensor fault exists (a sensor disconnect, failure, misalignment or
incapatability with the monitor) or if a pulse oximeter sensor signal is no longer detected, a dash
(-) appears in the left-most digit of the SpO2display. The readings that are displayed will freeze for
10 seconds if the pulse oximeter sensor fault or the inadequate signal continues. A sensor fault is
a medium priority alarm.
If the sensor fault or the inadequate signal is not corrected, the frozen readings and the left-most
dash will be replaced by dashes in the middle digit of both the SpO2and the Pulse Rate displays,
10 seconds after the first dash appeared.
When the sensor fault or the inadequate signal is corrected, the SpO2and pulse rate displays will
return to normal operation.

6
Displays and Indicators
Alarm Bar
The Alarm Bar flashes amber or red, indicating medium or high priority alarms, respectively. This
indicator is located near the top of the device.
Alarm Silence Indicator
The Alarm Silence indicator (identified by the symbol) is located to the left of the On/Off button.
Whenever the Alarm Silence indicator is flashing, all audible alarms are temporarily silenced. If
the alarm volume is set to “off,” the Alarm Silence indicator is lit solidly.
Pulse Rate Tone
When the Pulse Rate tone is active, a beep sounds for each detected pulse. This beep changes
in pitch with SpO2values. The default volume is OFF. During normal operation, the volume can
be changed (off, low, or high) by momentarily pressing the advance button.

Using the PalmSAT Pulse Oximeter
Using the PalmSAT Pulse Oximeter
The Model 2500A PalmSAT is a digital handheld pulse oximeter that displays numerical values for
blood oxygen saturation (%SpO2) and pulse rate. It provides audible and visual alarms for both
medium and high priority conditions.
This device will typically operate for 60 hours continuously between alkaline battery replacements,
or for 40 hours with the Model 2500B Rechargeable NiMH (Nickel Metal Hydride) Battery Pack
(optional). The device requires no routine calibration or maintenance other than replacement of
alkaline batteries or recharging the optional battery pack with the Model 2500C Charger Stand
(refer to the Model 2500C Operator’s Manual).
The pulse oximeter determines functional oxygen saturation of arterial hemoglobin (SpO2) by
measuring the absorption of red and infrared light passing through perfused tissue. Changes in
absorption caused by the pulsation of blood in the vascular bed are used to determine oxygen
saturation and pulse rate.
Figure 1: Displays, Indicators and Buttons
Oxygen saturation and pulse rate values are displayed by light-emitting diode (LED) digital
displays. On each detected pulse, the Pulse Quality display blinks. Patient pulse quality signals
are graded as good, marginal, or inadequate and are indicated as such by the Pulse Quality
display blinking green, amber 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.

Important Notes about Battery Use
Four AA alkaline batteries provide the device with approximately 60 hours of continuous operation,
while the Rechargeable NiMH Battery Pack provides approximately 40 hours of continuous operation.
Clock/calendar settings can significantly affect battery storage life. Batteries drain during
storage, but they drain much more quickly when the unit’s clock/calendar functions are set. Refer
to “Clock and Calendar Settings” for more information.
With AA Batteries
• If the clock/calendar is not set when the unit is stored, alkaline batteries will need
replacement in 10-12 months if the unit has not been used.
• If the clock/calendar is set when the unit is stored and if the unit has not been used,
alkaline batteries will require replacement in about 6 weeks.
• Using the oximeter will shorten the required replacement time.
With Rechargeable NiMH Battery Pack
• If the clock/calendar is not set when the unit is stored, and if the unit has not been used,
the Rechargeable NiMH Battery Pack will need recharging at least every 2 months.
• If the clock/calendar is set when the unit is stored, and if the unit has not been used, the
Rechargeable NiMH Battery Pack will need recharging at least every 3 weeks.
• Using the oximeter will shorten the required recharging time.
Recharging Batteries (NiMH Battery Pack only)
• Completely recharging the NiMH battery pack requires approximately 180 minutes when
the unit is completely discharged.
• The expected useful life of the Rechargeable NiMH battery pack is 500 charge/
discharge cycles, or approximately 10 years, whichever is first. The battery pack must
be charged at least once each year to maintain optimal battery life.
• AA alkaline batteries cannot be recharged in the charging stand.

Power On Self-Test
When the Model 2500A is turned on for normal operation, the unit will cycle through a startup/
initialization sequence before displaying valid data. During startup, always check for any missing
indicators or LED display segments and ensure that the audible indicator sounds. If any indicator is
not functioning, do not use the device. Contact Nonin Technical Service for repair or replacement.
During its normal startup sequence, the device will cycle as follows:
•“888 888” appears briefly in the SpO2and Pulse Rate displays.
• the amber Low Battery and Alarm Silence indicators turn on steadily for a few seconds.
• the Pulse Quality display turns red for 1 second, then green for 1 second, then shuts off,
while the Alarm Bar turns red for 1 second, then amber for 1 second.
• the clock time currently set in the memory (in hours and minutes, 04 41 for example)
appears briefly in the displays.
• the software revision numbers (display in the following order, each for approximately
1 second): Main revision “r” + 3 digits; Memory revision “n” “n” (for m) + 3 digits; Sound
revision “s” + 3 digits.
• three audible beeps sound.
• (two dashes) appear in the displays until a valid pulse signal is detected.
NOTES:
• The two-minute alarm silence feature is automatically enabled immediately after the startup
sequence.
• This startup sequence varies slightly when entering setup mode at power on.

12
Using the PalmSAT Pulse Oximeter
Monitoring
Verify that the pulse oximeter sensor is properly positioned on the patient. Ensure that the pulse
oximeter is sensing adequate pulse quality by:
• verifying that the Pulse Quality display is blinking green and
• verifying that the Pulse Rate and SpO2displays are displaying readings and
• verifying that blinking of the Pulse Quality display is in time with the pulse rate for at least
10 seconds
If the Pulse Quality display is blinking red or amber or is blinking erratically, reposition the sensor
or replace the sensor.
If the sensor is not properly positioned, or no sensor is attached to the pulse oximeter after startup
(a few seconds after powering on), both the SpO2 and Pulse Rate displays will display a single
dash until a valid pulse signal is detected.
