What are the two main types of sleep studies performed?

The correct answer identifies the two main types of sleep studies performed, which are polysomnography and home sleep apnea testing.

Polysomnography is an in-laboratory study that provides comprehensive monitoring of various physiological parameters during sleep, including brain activity (EEG), eye movements (EOG), muscle activity (EMG), heart rate, and respiratory function. This type of study is considered the gold standard for diagnosing sleep disorders, particularly sleep apnea, as it allows for real-time analysis and extensive data collection while the patient sleeps in a controlled environment.

Home sleep apnea testing is another essential method that allows for the evaluation of sleep-disordered breathing in patients within the comfort of their own home. This type of testing is usually less comprehensive than polysomnography, but it is often simpler and more cost-effective. It typically monitors fewer parameters, focusing mainly on respiratory function and oxygen saturation. This method is increasingly popular for the initial screening of obstructive sleep apnea due to its convenience and accessibility.

The other options involve methods that are not classified as the primary types of sleep studies. While wrist actigraphy is useful for monitoring sleep patterns and activity levels, it does not provide the same detailed physiological data as polysomnography. Sleep diary analysis is a subjective measure
