Pulse oximetry is a non-invasive medical technique used to measure the oxygen saturation level (SpO2) in the blood and monitor pulse rate. It involves placing a small device, called a pulse oximeter, on a peripheral part of the body, typically a finger, toe, or earlobe.
The pulse oximeter uses light wavelengths to detect the amount of oxygen-bound haemoglobin in the blood, providing real-time readings of oxygen saturation and pulse rate.
In first aid scenarios, pulse oximetry helps responders assess the casualty's respiratory status and overall oxygenation. It is particularly valuable in identifying conditions such as respiratory distress, hypoxia (low oxygen levels), or shock.
Continuous monitoring of pulse oximetry readings assists responders in making informed decisions about the need for oxygen therapy or escalation of medical care.
Portable and easy to use, pulse oximeters are essential tools in emergency response and critical care settings.
