Maternal Pulse Oximetry Monitoring: MSpO2 Technology
Pulse oximetry is a continuous and non-invasive method of measuring the level of
arterial oxygen saturation in blood. The measurement is usually taken by placing a
sensor on the adult patient's fingertip. The sensor is connected to the monitor by a
patient cable. The sensor collects signal data from the patient and sends it to the
monitor.
Pulse oximetry is governed by the following principles:
1. Oxyhemoglobin (oxygenated blood) and deoxyhemoglobin (non-oxygenated
blood) differ in their absorption of red and infrared light (spectrophotometry).
2. The amount of arterial blood in tissue changes with your pulse
(photoplethysmography).
Therefore, the amount of light absorbed by the varying quantities of arterial blood
changes as well. The 250cx Series Monitor measures the maternal oxygen saturation
(MSpO ) and pulse rate using the principles of spectrophotometry and
2
plethysmography.
