Finger-based pulse oximetry is a non-invasive medical technology used to measure the oxygen saturation level in a patient's blood. It involves placing a small, clip-like device called a pulse oximeter on a patient's fingertip or earlobe, which uses light sensors to detect the level of oxygen in the blood. This information is then displayed on a screen in real-time, allowing healthcare professionals to monitor a patient's oxygen levels and respiratory function. Finger-based pulse oximetry is a widely used and highly effective tool in both clinical and home settings, providing rapid and accurate measurements of a patient's oxygen saturation levels, and helping to identify potential respiratory complications before they become severe. With its ease of use and non-invasive nature, finger-based pulse oximetry has become an essential part of modern medical care, particularly in critical care settings such as intensive care units, emergency rooms, and operating theaters.
