Obstructive sleep apnea (OSA) is one of the disorders that can require a second sleep study, which will be performed with continuous positive airway pressure (CPAP) or bi-level positive airway pressure (BPAP), the most effective and widely used methods of treating sleep apnea.
While you are asleep, this system gently delivers air into your airway through a specially designed mask which fits over the nose or mouth, creating enough pressure to keep the airway open and produce immediate relief from sleep apnea and snoring. Most people find they get used to this apparatus after a few minutes and have little difficulty sleeping with it in place. It is important to note that the CPAP or BPAP machine does not breathe for you, but allows you to breathe on your own without having to fight any obstructions in the airway. At the beginning of a CPAP/BPAP study, sensors are applied to your body as they were for the polysomnogram and again brain waves, eye movements, breathing patterns and blood oxygen levels are monitored. Before you fall asleep, the sleep technologist will fit you with the mask.
