Monitoring Pulse Oxygen Saturation
(SpO
2
) (Optional)
9.1 Introduction
Pulse Oxygen Saturation (SpO
2
) monitoring is a non-invasive technique used to measure
the amount of oxygenated hemoglobin and pulse rate by measuring the absorption of
selected wavelengths of light. The light generated in the probe passes through the tissue
and is converted into electrical signals by the photo detector in the probe. The SpO
2
module processes the electrical signal and displays a waveform and digital values for SpO
2
and pulse rate.
The telemetry monitor can be configured with Masimo SpO
2
module or Nellcor SpO
2
module.
For details about the SpO
2
parameter setup at the Central Monitoring System, refer to
13 Monitoring with the Telemetry Monitor at the CMS .
NOTE
•
A functional tester or SpO
2
simulator cannot be used to assess the accuracy of a
SpO
2
module or a SpO
2
sensor.
•
This device is calibrated to display functional oxygen saturation.
•
A pulse oximeter should not be used as an apnea monitor.
•
Pulse rate measurement is based on the optical detection of a peripheral flow
pulse and therefore may not detect certain arrhythmias. The pulse oximeter
should not be used as a replacement or substitute for ECG based arrhythmia
analysis.
•
The MS board pulse oximeter can be used during defibrillation, but the
readings may be inaccurate for a short time.
9.2 Measurement Limitations
The following factors may influence the accuracy of SpO
2
measurement:
■ Patient physiological characteristics:
◆
Cardiac arrest
◆
Hypotension
