What phenomenon can occur due to improper oxygen management during flight?

Improper oxygen management during flight can lead to decompression sickness, also known as "the bends." This condition occurs when a rapid decrease in pressure causes dissolved gases, primarily nitrogen, to form bubbles in the bloodstream and tissues. When an aircraft ascends quickly or if there is a sudden loss of cabin pressure, the partial pressure of gases in the body reduces, which can cause nitrogen to come out of solution and create harmful bubbles.

Decompression sickness is particularly a risk for pilots and flight engineers who ascend to high altitudes without appropriate supplemental oxygen or pressurization management. Symptoms can range from joint pain to more severe neurological effects, making it essential to maintain proper oxygen levels throughout the flight.

In contrast, while visual illusions, loss of cabin pressure, and engine stalls are critical concerns during flight operations, they do not specifically result from oxygen management issues. Visual illusions can arise from environmental factors or flight conditions, loss of cabin pressure pertains to structural integrity or failure of the pressure system, and engine stalls relate to aerodynamic conditions or fuel supply issues, not oxygen management directly.
