When an
O
XI
M
AX
-compatible sensor is connected to the N-595, the pulse
oximeter will first read the information in the sensor memory chip, check it to
make sure that there are no errors, and then load the data to begin monitoring.
As the pulse oximeter reads the information, it flashes the sensor model
number on its display. This process takes a couple of seconds. Once the
reading process is complete, the sensor model number will stop flashing on
the display, and then the N-595 will begin monitoring. The sensor model
number disappears after the pulse oximeter starts tracking the patient’s SpO
2
and pulse rate.
Pulse Oximeters containing
O
XI
M
AX
technology, including the N-595, use
calibration data contained in the sensor in calculating the patient’s SpO
2
. By
having the calibration in the sensor, rather than the pulse oximeter, the
published accuracy of many sensors can be, because the calibration
coefficients can be tailored to each sensor. Consult the accuracy card included
with the pulse oximeter for specific accuracy information for the N-595 with
different Nellcor approved sensors.
The N-595 uses the information in the
O
XI
M
AX
-compatible sensor to tailor
troubleshooting messages for the clinician. The sensor contains coding that
tells the pulse oximeter what kind of sensor is being used. When deciding
what messages to display, the pulse oximeter takes into account the sensor
type and recommended patient site for that model. The N-595
O
XI
M
AX
system
therefore has an intelligent troubleshooting system.
