What does abnormal SPO2 (less than 95%) suggest?

An abnormal Spo2 level, defined as being below 95%, typically indicates that there is a potential issue with the respiratory system, leading to inadequate oxygen saturation in the blood. This suggests that the body may not be receiving enough oxygen, which could be indicative of respiratory distress or impairment.

When oxygen saturation levels drop below this threshold, it is critical to assess the patient's respiratory function and overall clinical status to determine possible underlying causes, such as obstructive lung disease, pneumonia, or other conditions affecting gas exchange. It emphasizes the importance of monitoring and evaluating patients with abnormal Spo2 levels to ensure appropriate interventions are initiated promptly.
