Dear Colleagues,
What are the main characteristic difference between decompression sickness DCS resulting by diving and altitude aviation?
- symptoms
- main parameter effects like ambient pressure, metabolic gas supersturation in vivo ... etc.
Best regards
Altitude DCS starts with barotrauma (lung, ears, intestines), then anoxia comes, then hypothermia, and caisson disease symptoms are to be the last (if altitude is 19,5 km or more - then tissues start to vaporize and emphysema appears). Altitude DCS consequences explosive decompression.
Diving DCS usually is not so fast...
Altitude sickness is form of acute pulmonary edema due to high and rapidly acclimatization leading to decrease in oxygen partial pressure at high altitude and barometric pressure difference. There is a risk of neurogenic edema also I think

Since altitude DCS can be either rapid or slow, it depends on the scenario. In a rapid decompression, many of the effects can happen very quickly such as hypoxia, cyanosis, ear/intestinal discomfort. Diving is most associated with things like the bends which are not as common in rapid decompression. If you mean long term exposure at high altitude such as among climbers, the effects may be more progressive. Altitude sickness may result in fluid in the lungs.
