NO BREATH SLEEP AND HEIGHT

If you are being treated for sleep apnea, it is essential to consult a sleep disorder specialist before traveling to high altitudes. Hypoxia typical of high elevations can exacerbate apnea symptoms.

 

People suffering from sleep apnea have an impaired chemoreceptor response to decreased oxygen and are more susceptible to high-altitude pulmonary edema (HAPE). Traveling to high altitudes is particularly dangerous for those whose oxygen saturation (SaO₂) is low at sea level.

 

PRE-TRIP CONSULTATION

 

A visit to the doctor allows for an assessment of the risks associated with staying at high altitudes and helps to adjust the travel plan. It is also worth discussing the possibility of using prophylactic medications and adjusting therapy with CPAP devices.

 

MEDICATION AND PROPHYLAXIS

 

Acetazolamide may reduce the number of apnea and hypopnea episodes in individuals with sleep apnea, which is why it is sometimes recommended as a prophylactic medication before and during high-altitude stays.

 

Travelers with a sleep apnea therapy machine should adjust the device settings in advance, considering the decrease in atmospheric pressure with increasing altitude.

 

SUMMARY

 

➤ Sleep apnea increases the risk of complications at altitude, including HAPE.

➤ Individuals with low oxygen saturation at sea level should avoid traveling to high mountains.

➤ A pre-trip consultation and appropriate pharmacological and equipment prophylaxis are crucial for safety.
