Overview
Pulse Oximetry monitoring is a non-invasive procedure to deter-
mine the functional oxygen saturation of the patient’s arterial
blood (SpO
2
) and an accompanying pulse rate.
A sensor is attached to the patient (usually the finger) and mea-
sures the absorption of light by the oxyhemoglobin. The light sent
through the tissue is transformed into a signal that is processed by
the monitor. The monitor is designed to:
! Display the oximetry waveform.
! Calculate the SpO
2
pulse rate.
! Identify critical levels of arterial oxygen saturation.
Sensor Application
The quality of SpO
2
measurements depends largely on the
strength and quality of the signal received by the sensor.
Infinity Gamma Series monitors support Nellcor and Masimo
SpO
2
sensors. The SpO
2
menu shows which sensor type is cur-
rently selected. If you connect a sensor different from the type
shown in the SpO
2
menu, the monitor displays an error message.
Selecting the sensor type is a password-protected function.To
change the sensor type, contact your Biomed department.
