Sleep Studies

PSG: Polysomnography: This is a diagnostic test that is performed to determine IF someone is having any sleep related disorders. It is a continuous recording of the heart rate, breathing, muscle and brain activities during sleep.


Home Sleep Studies: This study is ordered to be performed home. It can be performed if the patient has no co-morbidities and is usually performed on those who are unable to leave home or a nursing facility. It may also be ordered if a sleep related disorder is questionable. Only minimal education and training is required and the patient is sent home with the necessary equipment.

CPAP: Continuous Positive Airway Pressure: This is a therapeutic study that is performed to determine the level of severity of a sleep related disorder. It is a continuous recording of the heart rate, breathing, muscle and brain activities during sleep and a titration of airflow that is maintained until the patients apneic periods are controlled or omitted.

ASV: Adaptive Servo Ventilation: This study is performed if the patient has undergone unsuccessful CPAP/BI-level studies due to persistent apneic periods and/or displays periods of apnea accompanied by no chest movement in an attempt to breathe during those apneic periods. (Central apnea)
