Klämtrycket

Klämtrycket is a type of pressure sensation experienced by divers during a free ascent from a depth. It occurs when the air in the lungs is compressed due to the rapid decrease in atmospheric pressure as the diver ascends. This compression causes the air to expand, leading to a risk of lung overexpansion injuries.

The pressure at depth remains higher than the pressure at the surface, resulting in a pressure gradient that drives air into the lungs. When the diver breaks through the surface or rapidly ascends, the pressure outside the body suddenly drops, and the compressed air in the lungs expands rapidly. If the air in the lungs expands too quickly, it can cause damage to the lung tissues, leading to injuries or potentially more severe conditions.

Factors contributing to the risk of klämtrycket include rapid changes in depth, breathing gas composition, and fatigue. The risk can be mitigated through proper training, gradual ascent rates, and monitoring personal health conditions. In addition, divers can reduce the risk by avoiding deep dives, staying within established safe depth limits, and learning to recognize and respond to the symptoms of klämtrycket.

Divers should be aware of the signs of klämtrycket, which include severe chest pain, shortness of breath, and coughing. Immediate medical attention is crucial if symptoms persist or worsen. With proper knowledge and precautions, divers can minimize the risk of klämtrycket and enjoy safer and more enjoyable dives.
