The study involved 200 aircrew members, and identified a pattern of acute and chronic symptoms among affected aircrew, including headaches, dizziness, breathing problems, and vision problems. These symptoms can have a significant impact on the health and well-being of aircrew, potentially affecting their ability to perform their duties safely ...
It has been described in scuba divers, long-distance swimmers, and breath-hold divers. [11] [7] Preexisting cardiac disease and high blood pressure [2] [5] [3] Hypertension correlates with greater increases in peripheral vasoconstriction on cold exposure. Combined with diastolic dysfunction due to hypertrophy of left ventricular walls causes ...
Benadryl Allergy is widely used as a sleep aid among adults. While it is not marketed as an over-the-counter (OTC) sleeping aid, most versions of Benadryl contain diphenhydramine, a drug with sedative properties. [6] Diphenhydramine (Benadryl) has also been used by parents to help improve their infant's sleep habits.

Rates increased in 2020 due to COVID-19, with some cases also appearing similar to HAPE. [43] [44]

The elimination half-life of diphenhydramine has not been fully elucidated, but appears to range between 2.4 and 9.3 hours in healthy adults. [6] A 1985 review of antihistamine pharmacokinetics found that the elimination half-life of diphenhydramine ranged between 3.4 and 9.3 hours across five studies, with a median elimination half-life of 4.3 ...
Medium to long term exposure to high partial pressures (>c1.3 bar) of inert gas (usually N 2 or He) in the breathing gas. Decompression sickness ("the bends"): Injury due to gas bubbles expanding in the tissues and causing damage, or gas bubbles in the arterial circulation causing emboli and cutting off blood supply to tissues downstream of the ...
