What does the POIS tree stand for in diving medicine?

The term POIS tree in diving medicine refers specifically to "Pulmonary overinflation inducing syndromes." This concept is crucial because it describes a range of potential injuries that can occur when a diver ascends too quickly after experiencing pulmonary overinflation. This situation typically arises when air expands in the lungs during ascent, leading to barotrauma, which can cause serious complications such as arterial gas embolism or other life-threatening conditions.

Understanding the ramifications of pulmonary overinflation, such as its association with various syndromes, emphasizes the importance of safe diving practices, including the need for gradual ascents and adherence to decompression protocols. Divers must be educated on the signs and symptoms associated with potential pulmonary injuries to ensure quick and effective responses to any emerging issues.
