In COVID-19, the arterial and general tissue oxygen levels can drop without any initial warning.The chest x-ray may show diffuse pneumonia.Cases of silent hypoxia with COVID-19 have been reported for patients who did not experience shortness of breath or coughing until their oxygen levels had depressed to such a degree that they were at risk of acute respiratory distress (ARDS) and organ failure.
[1] [2] Chronic mountain sickness may occur after long-term exposure to high altitude. [2] Altitude sickness typically occurs only above 2,500 metres (8,000 ft), though some people are affected at lower altitudes. [2] [4] Risk factors include a prior episode of altitude sickness, a high degree of activity, and a rapid increase in elevation. [2]
The World Health Organization (WHO) this week issued a definition for "long COVID," a term used to describe the persistent health problems that affect some survivors of COVID-19. HOW DOES THE WHO ...
However, the human body has both short-term and long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen. There is a limit to the level of adaptation; mountaineers refer to the altitudes above 8,000 metres (26,000 ft) as the death zone , where it is generally believed that no human body can acclimatize .

Cases have also been reported between 1,500–2,500 metres or 4,900–8,200 feet in people who are at a higher risk or are more vulnerable to the effects of high altitude. Classically, HAPE occurs in persons normally living at low altitude who travel to an altitude above 2,500 meters (8,200 feet). [ 3 ]
Long COVID has mystified the medical community for years, making it a tough condition to diagnose, let alone treat. However, a growing body of research has found more information on what may be ...
