Does high-altitude affect CPAP?

Conclusions: For obstructive sleep apnea patients living at altitude, changes in elevation between 10,100 ft (3075 m) and sea level do not significantly alter absolute CPAP pressure requirements.

Will a CPAP machine help with altitude sickness?

CPAP and high-altitude pulmonary edema CPAP therapy is also a tested temporary treatment for people who suffer from a very severe form of altitude sickness, high-altitude pulmonary edema (HAPE).

Does head elevation help sleep apnea?

“Sleeping with the head as elevated and upright as possible, such as with an adjustable bed or in a recliner, may be helpful in improving sleep apnea symptoms.” Wedge-shaped pillows made of foam (rather than a squishier material) can help you achieve the right position that keeps the airway more open.

Does CPAP raise oxygen levels?

CPAP therapy corrects low levels of oxygen in the blood and reduces pauses in breathing. CPAP provides a steady flow of air through a facemask that is worn while sleeping.

Is sleep apnea worse at high altitudes?

For those with sleep apnea, higher altitude can definitely make breathing more difficult. In a 2011 study, researchers found that those living at higher altitudes which had moderate-to-severe obstructive sleep apnea were also more likely to develop central sleep apnea.

Does high altitude affect your sleep?

Sleep Disturbances Trouble sleeping is quite common at high altitude. The low oxygen directly affects the sleep center of the brain. Frequent awakenings, a light sleep and less total time of sleep are the main problems, and these usually improve with acclimatization after a few nights.

Why does high altitude cause central sleep apnea?

At altitude, the reduced oxygen content of the blood induces breathing instability, with periods of deep and rapid breathing alternating with central apnea. This breathing pattern is called high-altitude periodic breathing.

What is the best sleeping position for CPAP?

Sleeping on your side is one of the best positions for sleep apnea treatment, since it prevents gravity from impacting your airway the way it does when sleeping on your back or stomach. Unfortunately, side sleepers sometimes struggle to find the right CPAP mask.

What helps breathing at high altitudes?

The medication acetazolamide can reduce symptoms of altitude sickness and help improve labored breathing. You may also be given the steroid dexamethasone. Other treatments include a lung inhaler, high blood pressure medication (nifedipine), and a phosphodiesterase inhibitor medication.
