sounds including alarms are operational, indicating that
the monitor is functioning. Each valid button press
should generate an appropriate audible or visual action.
Observe movement of the Pulse Amplitude Indicator or
pleth waveforin, and listen for pulse beeps to verify that
measureinents are being made.
Note: If any action does not seem appropriate, do not use the
monitor. Instead, contact Mallinckrodt Technical
Services Department or your local Mallinckrodt
representative.
In Monitoring Mode, if the acquired pulse is lost, the monitor
enters Pulse Search Mode.
Pulse Search
If the acquired pulse is lost during monitoring, the N-395 enters
Pulse Search. During Pulse Search, the monitor attempts to
detect a pulse from which to take a measurement.
At initial Power-Up (Sensor Attached to Monitor)
Immediately after POST is completed and the N-395 displays its
software version nuinber, the monitor enters Pulse Search Mode
and the Pulse Search Indicator lights. If an attached sensor is
not connected to a patient, the display reads zeroes and the
monitor remains in the Pulse Search Mode for about 5 seconds.
After 5 seconds the pulse search is turned off and SpO2 and
Pulse Rate display "--- & --- " (dashes and dashes). If the sensor
is connected to the patient, the N-395 enters the Monitoring
Mode when a pulse is detected.
At initial Power-Up (No Sensor Attached to Monitor)
Immediately after POST is completed and the N-395 displays its
software version number, the monitor displays dashes. It does
not enter the Pulse Search Mode.
