Scuba diving fatalities high drag of an excessively inflated buoyancy compensator, leading to exhaustion or panic which resulted in drowning. Excessive depth was considered a factor in 12% of fatalities summarized by Edmonds et al. The fatal dive was often the deepest ever for the victim. Greater depth can expose a diver to factors such as increased air consumption, impaired judgment caused by nitrogen narcosis, colder water, reduced thermal insulation of a compressed wetsuit, reduced visibility and lighting, slower response of buoyancy compensator inflation, increased work of breathing, greater heat loss when using helium mixtures, higher risk of decompression sickness and a necessarily
