General Description
Pulse oximetry is a continuous and non-invasive method of measuring the level of arterial oxygen
saturation in blood. The measurement is taken by placing a sensor on a patient, usually on the
fingertip for adults, and the hand or foot for neonates. The sensor connects to the pulse oximetry
instrument with a patient cable. The sensor collects signal data from the patient and sends it to the
instrument. The instrument displays the calculated data in two ways:
1) As a percent value for arterial oxygen saturation (SpO
2
)
2) As a pulse rate (PR)
The following figure shows the general monitoring setup.
