What is an optional parameter that can be included in an adult polysomnogram report according to guidelines?

The inclusion of the occurrence of hypoventilation in an adult polysomnogram report is considered an optional parameter because it may vary depending on the specific clinical scenario and the focus of the sleep study being conducted. While essential parameters such as the presence of sleep apnea, duration of REM sleep, and depth of sleep stages are critical components that provide significant insights into a patient's sleep disorders, hypoventilation is sometimes assessed but not universally required.

In many cases, hypoventilation can be relevant in specific patient populations, particularly those with certain comorbidities or conditions affecting breathing during sleep. Therefore, the decision to include this parameter depends on the context of the study and the clinical questions posed by the healthcare provider. Thus, including the occurrence of hypoventilation allows for a more tailored interpretation of the data when necessary.
