Diving Precautions and Prevention of Diving Injuries
Contraindications to diving
Because diving can involve heavy exertion, divers should not have a functionally significant cardiovascular or pulmonary disorder and should have adequate aerobic capacity for the type of diving performed. Disorders that can impair consciousness, alertness, or judgment generally contraindicate diving. If there is any doubt as to whether diving is contraindicated by a specific disorder, a recognized expert should be consulted. For specific diving contraindications, see table.
