A Wetsuit Diver’s Guide To Maintaining Body Heat

A Wetsuit Diver’s Guide To Maintaining Body Heat | All about water, the oceans, environmental issues | Scoop.it

Being cold is usually unpleasant, but when it comes to diving, being cold can be dangerous, too. When you become chilled underwater, you lose functionality, strength, and the ability to concentrate on anything other than your own discomfort. In extreme cases, being cold can lead to hypothermia, which is a harmful drop in body temperature to below 95 Fahrenheit (35 C). It can lead to impaired judgment, uncontrollable shivering and, in extreme cases, unconsciousness and death. In addition, loss of body heat is associated with an increased risk of decompression sickness, because when you’re cold, your body constricts its blood vessels in an attempt to conserve heat. In a diving scenario, this means blood off-gasses nitrogen slower than your dive computer or RDP anticipates.

Rebreather Fatalities | DIVER magazine

Rebreather Fatalities | DIVER magazine | All about water, the oceans, environmental issues | Scoop.it

When diving open circuit you are virtually always okay if you have gas to breathe.  This stops being true when you move into technical diving where breathing your decompression gas too deep can kill you from an oxygen (O2) seizure and breathing your bottom gas for a deep trimix dive too shallow can kill you from hypoxia.  When diving a rebreather the gas you are breathing can kill you if the partial pressure of oxygen in the gas is too high or too low, or if the partial pressure of carbon dioxide is too high.  Experienced open circuit divers intuitively believe that as long as they have gas to breathe they are okay and as a result often forget to monitor the partial pressure of oxygen (pO2) in the breathing loop on a rebreather.  This is frequently a factor in rebreather accidents.
