Oxygen intake can relieve high altitude sickness to a certain extent.
High altitude reaction is mainly caused by lack of oxygen, so inhaling oxygen can fundamentally relieve the symptoms of high altitude reaction. At the same time, the patient needs to be sent to a place of lower altitude as soon as possible, and can be relieved by descending about 300-1000 meters. After the symptoms are relieved, you can continue to ascend, but if there are persistent symptoms, do not ascend further or to the previous altitude.
When altitude reaction causes more serious headache, you can take some analgesic drugs such as ibuprofen and acetaminophen as prescribed by your doctor. If nausea or vomiting is present, prochlorperazine can be injected into the muscle, and the specific medication should be chosen according to the symptoms.
If the symptoms cannot be relieved or even continue to worsen after taking oxygen, lowering the altitude, or taking medication, the patient should seek medical attention as soon as possible.
