What assessment method is used to diagnose sleep apnea?

• A. Blood test
• B. Polysomnography
• C. X-ray
• D. Psychological evaluation

Answer: (B)

Polysomnography is the gold standard for diagnosing sleep apnea. This comprehensive sleep study records brain waves, oxygen levels in the blood, heart rate, respiratory effort, and eye and leg movements while the patient sleeps. By capturing this array of data, healthcare providers can observe the patient’s sleep cycles and identify disruptions in breathing patterns that characterize sleep apnea. The information gathered can help determine the severity of the condition and guide appropriate treatment options.

In contrast, blood tests evaluate various health markers but do not specifically diagnose sleep apnea, X-rays primarily assess the structure of bones and certain organs without providing the necessary information about sleep patterns, and psychological evaluations focus on mental health rather than the physiological aspects of sleep disorders. Therefore, polysomnography remains the definitive method for accurately diagnosing sleep apnea.
