A number of obstructive sleep apnea cases are due to sleep position. Airway collapse can occur more frequently when a patient is sleeping on their back. To address this issue, there are several products available that can address positional sleep apnea. This positional sleep aids guide compares devices on parameters including how the device works, acclimation period, FDA status, prescription versus over-the-counter, price, power supply, weight, data recorded, dimensions, warranties, reimbursement, and more.

| How It Works | Worn around the neck or chest, Night Shift begins to vibrate when the user initiates supine sleep. The vibration slowly increases in intensity until a position change occurs. Night Shift is also an intelligent, interactive monitor that measures sleep quality and the frequency of unhealthy loud snoring. | The CPAPMax Pillow has an orthopedic design, 4 height options, reversible cool mesh and plush fiber-fill sides, and side cutouts that help users find the perfect position—even while wearing a CPAP mask. A tether keeps the CPAP hose in place so it doesn’t pull on the mask. The pillow can be used by back, side, or stomach sleepers and works with all CPAP therapy brands. It is designed to reduce leaks, noise, and dry eyes. | The Sleep Noodle helps to provide positional therapy by using its foam insert to ensure comfort but sufficient support to maintain side sleeping. An industrial strength hook-and-loop fastener ensures the belt maintains its connection while wrapped around the user. | Philips NightBalance is a clinically-validated positional therapy that uses gentle vibrations to encourage users to alter their sleeping positions to help prevent apneas. | The Bumper Belt helps prevent a person from sleeping on their back. Worn while sleeping, its adjustable inflatable bumpers hold users on their sides. | Designed by a board-certified sleep physician and worn around the upper torso, ZZOMA treats mild to moderate positional obstructive sleep apnea and snoring by ensuring patients remain on their side while sleeping—normalizing sleep quality while minimizing nighttime disruption and daytime fatigue. | ||
| Acclimation Period | After the first night of use, a patient will know if the device is effective, based on how many times he/she attempted to sleep supine and how quickly he/she responded to the vibrotactile feedback. | N/A | 14 days | The adaptation program is designed to slowly train the user to respond to the sensor device’s vibrations during sleep. Patients need to use NightBalance for 9 nights before the device will provide full therapy. | A properly sized belt is immediately effective. | ~2 weeks | ||
