Want to enjoy diving longer?
Monitor your gas, watch out for entrapment possibilities and older divers get a full physical, including an appropriate assesment of cardiac function.

Diving fatalities causes were investigated in 947 recreational open-circuit scuba diving deaths from 1992-2003. Where possible, cases were classified at each step of a four step sequence: trigger, disabling agent, disabling injury, cause of death (COD).
The most frequent adverse events within each step were: (a) triggers -- 41% insufficient gas, 20% entrapment, 15% equipment problems; (b) disabling agents--55% emergency ascent, 27% insufficient gas, 13% buoyancy trouble; (c) disabling injuries--33% asphyxia, 29% arterial gas embolism (AGE), 26% cardiac incidents; and (d) COD--70% drowning, 14% AGE, 13% cardiac incidents.
We concluded that disabling injuries were more relevant than COD as drowning was often secondary to a disabling injury."
