There are several alternatives to CPAP machines for obstructive sleep apnea (OSA), including BiPAP machines, auto-adjusting positive airway pressure (APAP) machines, and expiratory positive airway pressure (EPAP) therapy, which is a device that uses valves to create pressure when you exhale. There is also an emerging therapy called hypoglossal nerve stimulation, commonly referred to as the Inspire system.15 This method involves the insertion of three different sensors under the skin of a patient’s neck and chest to monitor your breathing and mildly stimulate the nerves controlling your tongue to help keep the airway open during sleep.
