What oxygen saturation level is considered abnormal?

An oxygen saturation level of 92% or lower is considered abnormal because it indicates that the body may not be receiving enough oxygen. Normal oxygen saturation levels typically range from 95% to 100%. When levels drop below 95%, especially reaching or falling below 92%, it raises concerns about potential respiratory or cardiovascular issues. At this point, there may be a need for medical evaluation or intervention to address hypoxia, which can lead to serious health complications if not managed properly. Recognizing these levels is crucial for ensuring the health and safety of individuals, particularly those with respiratory ailments.
