Preparations for the sleep study

WithRavi Gupta, S. R. Pandi Perumal, Ahmed S. BaHammam

This chapter discusses the optimal environment and setting of a sleep laboratory. It focuses on the equipment for electrical safety. The chapter analyses the patient for optimal recording of data during polysomnography. It provides instructions to the patient for optimal recording. The sleep laboratory should be situated away from a crowded and noisy area and its decor should be attractive and homely. It must have adequate ventilation and provision for daylight. The laboratory must provide means for the patient to communicate with the sleep technician anytime during the recording, without reaching for the phone. Polysomnography machines require electrical power for their working and so they are connected to the electrical supply that usually has 240 V current. These machines also have capacitors and transformers, in addition to the integrated circuits.
