Altitude Sickness | Acute Mountain Sickness | High Altitude Pulmonary Edema | Respiratory Lecture-9

High altitude sickness, including acute mountain sickness (AMS), high altitude pulmonary edema (HAPE), high altitude cerebral edema (HACE), chronic mountain sickness, and other high altitude related illnesses, are explained in a simple way in this video.

This video explains altitude sickness, in the detail. The definition, pathophysiology, clinical features, diagnosis, treatment and prevention of altitude sickness, acute mountain sickness, high altitude pulmonary edema, high altitude cerebral edema and chronic mountain sickness is explained by expert clinician in this video.

Altitude sickness is the negative health effect of high altitude, caused by rapid exposure to low amounts of oxygen at high elevation. People can respond to high altitude in different ways. Symptoms may include headaches, vomiting, tiredness, confusion, trouble sleeping, and dizziness. Acute mountain sickness, milder form of altitude sickness, can progress to high altitude pulmonary edema (HAPE) with associated shortness of breath or high altitude cerebral edema (HACE) with associated confusion. Chronic mountain sickness can develop after long term exposure to high altitude.

Altitude sickness typically occurs above the height of 2,500 meters (8,000 ft), though some are affected at lower altitudes. Some of the important risk factors for altitude sickness include a prior episode of altitude sickness, a high degree of activity, and a rapid increase in elevation. Diagnosis of the altitude sickness is based on symptoms and is supported in those who have more than a minor reduction in activities. It is suggested that at high-altitude any symptoms of headache, nausea, shortness of breath, or vomiting should be assumed to be altitude sickness and treated promptly. Timely treatment of acute mountain sickness can prevent the progression to high altitude pulmonary edema and high altitude cerebral edema which can be life threatening.

This video is useful for medical students, nursing students, clinicians, and for those students preparing for competitive exams like USMLE, MRCP, PLAB, AMC, NCLEX, DHA, NEET etc.
