Why is reviewing a patient's medical history important before a polysomnography?

Reviewing a patient's medical history before conducting a polysomnography is essential because it helps identify risk factors that may influence the patient’s sleep patterns and overall health. Understanding the patient’s previous health issues allows clinicians to tailor the polysomnography to assess for specific conditions, such as sleep apnea, narcolepsy, or other sleep disorders. Additionally, knowing past medical history can help detect co-morbidities that may affect the results of the sleep study or the patient's response to treatment. This understanding not only guides the testing procedures but also informs subsequent clinical management and intervention strategies for optimal patient care.
