What would an SpO2 reading of 88% indicate?

An SpO2 reading of 88% indicates that the patient is experiencing hypoxemia, which refers to a deficiency in the amount of oxygen reaching the tissues. Normal SpO2 levels typically range from 95% to 100%. A reading of 88% falls significantly below this range and suggests that the body is not receiving sufficient oxygen. This condition can lead to various health complications if not addressed promptly.

Monitoring oxygen saturation is crucial in clinical settings, as low levels can impair the body's ability to function properly, resulting in symptoms like shortness of breath, rapid heart rate, and cyanosis. In cases where SpO2 levels are below 90%, especially at readings like 88%, immediate medical evaluation and possible intervention, such as supplemental oxygen therapy, may be necessary to prevent further complications.

Understanding this concept is essential for recognizing when patients require urgent care due to inadequate oxygenation. The other provided options do not accurately represent the clinical significance of an SpO2 reading of 88%. Normal oxygen levels do not align with this value, nor is there a direct correlation to hypertension or an elevated risk of infections based solely on SpO2 measurements.
