Nurse Call Interface
WARNING: The nurse call feature should not be used as the primary
source of alarm notification. The audible and visual alarms of the
pulse oximeter, used in conjunction with clinical signs and symptoms,
are the primary sources for notifying medical personnel that an
alarm condition exists.
WARNING: The nurse call feature is not functional whenever the
pulse oximeter alarms are silenced.
Caution: The nurse call function needs to be tested after it has been
set up in your facility. The nurse call feature should be tested
whenever setting up the N-560 pulse oximeter in a location that uses
nurse call. If an attached
O
XI
M
AX
sensor is disconnected from the
patient, the N-560 remains in the Pulse Search Mode for awhile, then
the N-560 displays “--- “ (3 dashes) in the %SpO
2
and pulse rate
display. One way to test the nurse call function is to create an alarm
condition (for example, sensor disconnect) and verify that your
facility's nurse call system is activated.
The nurse call feature of the N-560 is operational when the N-560 is
powered by AC power or battery power. The nurse call feature of the
N-560 works in conjunction with the nurse call system of your institution
when the N-560 sounds an audible alarm.
The N-560 provides two different types of nurse call interfaces: an
RS-232 format and relay closure. Both interfaces function when the
N-560 is operating either on AC power or battery power.
The remote location is signaled anytime there is an audible alarm. If the
audible alarm has been turned off or silenced, the nurse call function is
also turned off.
