What is minimum spo2 level in humans?

The minimum SpO2 (peripheral capillary oxygen saturation) level considered acceptable in healthy adults is typically around 95% to 100%. Levels below 90% are generally regarded as hypoxemia and can indicate inadequate oxygenation, potentially requiring medical attention. However, individual tolerances may vary, especially in people with chronic respiratory conditions. It’s essential to monitor SpO2 levels regularly, especially in vulnerable populations.
