Decompressiemodel

Decompressiemodel refers to a computational or mathematical framework used to understand and predict the process of decompression sickness, commonly known as "the bends." This condition affects divers and individuals exposed to rapid changes in ambient pressure. The core principle behind decompressiemodels is based on the behavior of inert gases, primarily nitrogen, dissolving into and out of the body's tissues under varying pressures.

At increased pressures, such as during diving, more inert gas dissolves into the tissues. If the pressure is reduced too quickly, these dissolved gases can come out of solution as bubbles, similar to opening a carbonated beverage. These bubbles can obstruct blood flow, damage tissues, and cause a range of symptoms from joint pain to paralysis and even death. Decompressiemodels aim to calculate how much gas dissolves into different tissue types and how quickly it can be safely eliminated from the body upon ascent.

Various decompressiemodels exist, each with different algorithms and assumptions about tissue perfusion and gas uptake/release. Early models were based on empirical observations and simple linear relationships. More advanced models incorporate concepts like tissue compartments with varying half-lives for gas exchange, reflecting the differing rates at which various body tissues absorb and release gases. These models are crucial for developing dive tables and dive computers, which provide divers with guidelines for safe ascent rates and required decompression stops to prevent or minimize the risk of decompression sickness.
