Understanding Decompression Illness

Decompression illness encompasses two main types: decompression sickness (DCS) and arterial gas embolism (AGE). DCS occurs when nitrogen bubbles form in the body tissues due to rapid ascension and decreased pressure, affecting various systems such as joints, muscles, and sometimes the nervous system. AGE, while more commonly associated with diving, can theoretically occur at altitude if an anatomical condition allows for the bypass of the pulmonary filtration system, particularly in cases of right-to-left shunt. Understanding these distinctions is crucial for accurate diagnosis and treatment, emphasizing the need for medical personnel to communicate clearly about symptoms and potential cases after high-altitude exposure.
