Pulse oximetry results are used to analyze symptoms of which problems?

• A. Cardiovascular and respiratory distress problems
• B. Digestive disorders
• C. Neurological deficits
• D. Skin conditions

Answer: (A)

Pulse oximetry measures arterial oxygen saturation and pulse rate, giving a readout of how well oxygen is moving from the lungs into the blood and how effectively the blood is being delivered to tissues. Because of that, it’s most useful for assessing problems in the respiratory system and the cardiovascular system. When someone has respiratory distress or heart/circulation issues, oxygen saturation can drop or vary, helping clinicians gauge the severity and progress of symptoms like shortness of breath, rapid breathing, chest discomfort, or cyanosis. It isn’t used to diagnose digestive disorders, neurological deficits, or skin conditions, which involve different bodily systems and tests.
