Acclimatization To Diving In Cold Water

by Dr. Jolie Bookspan BRIEF OVERVIEW OF SUSCEPTIBILITY TO COLD Just as the „dose” of nitrogen or oxygen, meaning partial pressure and time exposed, are main factors in decompression sickness and oxygen toxicity respectively, major factors in cold stress are temperature and length of exposure. As with dosage of any drug or substance, several interacting […]

Thermal Protection and Hypothermia Considerations

Introduction Thermal protection is paramount for undersea recreation, effective work, and military warfare needs. Heat loss is accentuated by many factors including the increased thermal conductivity of water as compared to air of the same temperature. The study of immersion hypothermia has increased survivability in downed pilots and aircrew, shipwreck victims, sport scuba enthusiasts, and […]

Cold Water Near-Drowning

Are cold water near-drowning victims any different from warm water victims? Submersion accidents which lead to unconsciousness in waters colder than 70 degrees F occur with regularity. Oxygen needs are much reduced when the body is cold, therefore a permanent brain damage from low oxygen states may not occur. A 60 minute cold water submersion […]

Immersion Hypothermia

Why is hypothermia dangerous? Hypothermia may be mild, moderate, or severe. The presentation may range from shivering and piloerection („goosebumps”), to profound confusion, irreversible coma and death. Significant hypothermia begins at temperatures of 95 degrees F and below. The lowering of the body temperature occurs as the body is robbed of heat by the surroundings. […]

Problems With Moving Water

Signs of a Current Each diver can detect signs of current, such as: 1). fast moving surface water; 2). which way the boat is facing (depending on whichever is the stronger, the current or the wind); 3). movement of floating material on the water or in the water; 4). movement of divers away from the […]

Seven Steps To Survival Survival at sea depends on the recognition that you are in danger of losing your life. There […]

Pre-Dive Risk Assessment

Things divers need to consider in prevention of diving accidents:1. Careful selection and predive physical examination of the divers.2. Careful selection of the appropriate equipment and gas mixtures for the dive.3. Careful predive planning to identify potential problems and formulate contingency plans. Predive planning includes:—Proper scheduling to avoid fatigue, to remain within O2 limits, and […]
