Animated SpO2 meter decreasing from normal to low level, ideal for concepts related to low oxygen saturation, hypoxemia and respiratory health

Pulse Oximetry Pulse oximetry is a simple, non-invasive method used to measure the oxygen saturation level (SpO₂) in the blood and monitor heart rate. It works by placing a small sensor, usually on a finger, toe, or earlobe, which uses light absorption to estimate how much oxygen is carried by hemoglobin. Pulse oximetry is widely used in hospitals, clinics, and home settings to assess respiratory and cardiovascular status, especially in patients with lung diseases, heart conditions, or during an

What Is Pulse Oximetry and How To Use A Pulse Oximeter To Measure Blood Oxygen Levels

Since this is a topic right now. Pulse oximetry. I wanted to use this to share the fight for every baby's heart. Seeing it being used as a call bell is disgusting. Specially in a NICU. What is newborn screening for critical congenital heart disease? Newborn screening for critical congenital heart disease uses pulse oximetry to check the level of oxygen in the blood of newborns. This test is painless and non-invasive. As of 2018, policies for screening newborns have been implemented in all states
