Introduction Monitoring SpO2 (Optional)
8 - 2 TMS60 Operator’s Manual
8.1 Introduction
The chapter describes the SpO
2
monitoring function at the TD60 in detail, including
connecting the SpO
2
module, configuring the SpO
2
, and monitoring the SpO
2
. For
details about the SpO
2
parameter setup at the central station (CS), refer to Chapter 9
Monitoring with the TD60 at the CS.
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 TD60 can be configured with Masimo SpO
2
or Nonin SpO
2
.
8.2 Measurement Limitations
If the SpO
2
measurement seems out of range or inaccurate, check the patient’s vital
signs. Then check the equipment and SpO
2
sensor. The following factors may influence
the accuracy of measurement:
■ Ambient light
■ Physical movement
■ Low perfusion
■ Electromagnetic interference
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.
