Final answer:
Decompression sickness can be predisposed by factors such as rapid ascent, frequent diving without enough surface intervals, dehydration, flying soon after diving, and physical exertion related to diving activities.
Step-by-step explanation:
Factors Predisposing Divers to Decompression Sickness
Decompression sickness (DCS), also known as "the bends," can be predisposed by several factors, which include:
- A rapid ascent rate, where divers ascend faster than 10 or 20 m/min without proper decompression stops.
- Frequent or multiple dives without appropriate intervals between them, which can increase the nitrogen load in the body.
- Dehydration, which can thickens the blood and impairs the elimination of dissolved gases.
- Flying soon after diving, as the reduced cabin pressure can exacerbate the release of nitrogen from the tissues.
- Physical exertion before, during, or after a dive, which can increase the circulation of nitrogen bubbles within the body.
Understanding and managing these factors can reduce the risk of DCS. When preventive measures fail, treatment in a hyperbaric oxygen therapy within decompression chambers may be required.
