What should be monitored in clients prone to oxygen desaturation during exercise?

• A. Only heart rate is important.
• B. Blood pressure is irrelevant.
• C. Continuous SpO2 monitoring; supplemental oxygen should be available.
• D. Temperature monitoring is sufficient.

Answer: (C)

During exercise, some clients may desaturate as the body's demand for oxygen increases and their lungs or circulation can’t keep up. Continuous monitoring of blood oxygen saturation (SpO2) with a pulse oximeter gives real-time information about how well oxygen is being carried in the blood, allowing immediate detection of desaturation and quick intervention. Having supplemental oxygen readily available is a safety precaution to prevent significant hypoxemia if desaturation occurs. Relying only on heart rate can miss hypoxemia because heart rate can rise even when oxygen levels drop, and blood pressure, while important to watch, does not reveal gas exchange status. Temperature monitoring alone doesn’t address oxygen saturation and isn’t a reliable indicator of desaturation during exercise.
