Morning anons…
Flying is like scuba diving. You have to be aware of PRESSURE and its effects on blood.
So we can die of an altitude like sickness=hypoxia
Or we can die by a pressure like sickness called decompression sickness
both have to do withBLOOD, itsTHICKNESS, and its ability to carryOXYGEN
Don't think we have examined the PRESSURE/THICKNESS/FLOW issues yet…
Any fluid dynamic folks 'bout?
"Decompression sickness (abbreviated DCS; also called divers' disease, the bends, aerobullosis, and caisson disease) is a medical condition caused by dissolved gases emerging from solution as bubbles inside the body tissues during decompression. DCS most commonly occurs during or soon after a decompression ascent from underwater diving, but can also result from other causes of depressurisation, such as emerging from a caisson, decompression from saturation, flying in an unpressurised aircraft at high altitude, and extravehicular activity from spacecraft. DCS and arterial gas embolism are collectively referred to as decompression illness.
Since bubbles can form in or migrate to any part of the body, DCS can produce many symptoms, and its effects may vary from joint pain and rashes to paralysis and death. Individual susceptibility can vary from day to day, and different individuals under the same conditions may be affected differently or not at all. The classification of types of DCS by its symptoms has evolved since its original description in the 19th century. The severity of symptoms varies from barely noticeable to rapidly fatal."
