SpO2 stands for peripheral capillary oxygen saturation. It is a measure of the amount of oxygen in the blood, expressed as a percentage. This measurement is commonly obtained using a pulse oximeter, which is a non-invasive device that clips onto a person's finger. Monitoring SpO2 levels is important in assessing a person's respiratory function and oxygenation status. **

Brain cells begin to die when SpO2 levels drop below 90%. Prolonged periods of low oxygen levels, particularly below 85%, can lead to irreversible brain damage and cell death. It is crucial to maintain adequate oxygen levels to ensure the brain receives enough oxygen to function properly and prevent damage. **
