Technology
The N-600x pulse oximeter is designed to use Nellcor O
XI
M
AX
brand
sensors, which integrate the O
XI
M
AX
technology. These O
XI
M
AX
sensors can be identified by their deep lavender/blue plug color. All
O
XI
M
AX
sensors contain a memory chip carrying information about
the O
XI
M
AX
sensor, which the oximeter needs for correct operation,
including the O
XI
M
AX
sensor’s calibration data, model type,
troubleshooting codes, and error detection data. This unique oximetry
architecture enables development of new sensors as well as several
new features with the
O
XI
M
AX
sensor N-600x.
When an O
XI
M
AX
sensor is connected to the N-600x, the pulse
oximeter will first reads the information in the O
XI
M
AX
sensor
memory chip, checks it to make sure that there are no errors, and then
loads the data to begin monitoring. As the pulse oximeter reads the
information, it displays the
O
XI
M
AX
sensor model number. This
process only takes a couple of seconds. The O
XI
M
AX
sensor model
number disappears after 5 seconds.
Pulse oximeters containing O
XI
M
AX
technology, including the
N-600x, use calibration data contained in the O
XI
M
AX
sensor in
calculating the patient’s SpO

. Consult the O
XI
M
AX
sensor accuracy
grid card included with the pulse oximeter for specific accuracy
information for the N-600x with different Nellcor
O
XI
M
AX
sensors.
The N-600x uses the information in the O
XI
M
AX
sensor to tailor
troubleshooting messages for the clinician. The O
XI
M
AX
sensor
contains coding that tells the pulse oximeter what kind of O
XI
M
AX
sensor is being used. When deciding what messages to display, the
pulse oximeter takes into account the
O
XI
M
AX
sensor type and
recommended patient site for that model.
