What oxygen saturation level is deemed abnormal?

An oxygen saturation level of less than 92% is considered abnormal because it indicates that the body's tissues may not be getting enough oxygen to function optimally. Normal oxygen saturation typically falls within the range of 95% to 100% in healthy individuals. When levels drop below 92%, it often prompts further evaluation and management, as prolonged low saturation can lead to hypoxia, which can affect organ function and overall health.

Levels below the other mentioned thresholds can also signal concerns, but 92% serves as a critical cutoff point where medical intervention is generally recommended. Thus, in clinical settings, sustaining oxygen saturation above this level is vital for maintaining a patient's well-being.
