The pulse oximetry measurement (SpO
Philips pulse oximetry uses a motion-tolerant signal processing algorithm, based on Fourier Artifact
Suppression Technology (FAST). It provides two measurements:
Oxygen saturation of arterial blood (SpO
the sum of oxyhemoglobin and deoxyhemoglobin (functional arterial oxygen saturation).
Pulse rate - detected arterial pulsations per minute. This is derived from the SpO
of four sources of the maternal heart/pulse rate used for cross-channel verification (see
"Monitoring Maternal Heart / Pulse Rate" on page 213 and "Cross-Channel Verification (CCV)"
on page 135).
Selecting an SpO2 Sensor
See "Accessories and Supplies" on page 249 for a list of sensors, and the patient population and
application sites for which they are appropriate.
Familiarize yourself with the Instructions for Use supplied with your sensor before using it.
Do not use OxiCliq disposable sensors in a high humidity environment, or in the presence of fluids,
which may contaminate sensor and electrical connections causing unreliable or intermittent
measurements. Do not use disposable sensors when there is a known allergic reaction to the adhesive.
Applying the Sensor
Follow the SpO
Remove colored nail polish from the application site.
Apply the sensor to the patient. The application site should match the sensor size so that the
sensor can neither fall off, nor apply excessive pressure.
Check that the light emitter and the photodetector are directly opposite each other. All light from
the emitter must pass through the patient's tissue.
