Treatment. As soon as someone notices symptoms, they need to descend and seek medical attention. If someone has labored breathing, the doctor might give them a medicine to improve breathing and reduce other symptoms of altitude sickness. To reduce pressure in the lung’s arteries, doctors may prescribe medication or an inhaler. If someone is not able to breathe on their own, they might need to be put on a breathing machine until they regain the ability to breathe independently. Treatment also includes getting plenty of rest and fluids.
