Positive pressure breathing for altitude sickness prevention
Part of Lungs & breathing clinical trials.
This study tests whether using a special breathing device that creates positive pressure can help prevent acute mountain sickness (symptoms like headache, nausea, and dizziness at high altitude). It is for healthy, experienced climbers planning an expedition on Mount Aconcagua.
