Studies show that if the huddle is formed so that the sides of the chest of dif- ferent persons are held close together, a 50% increase in predicted survival time is obtained. As with HELP this is a difficult procedure to maintain and it is advisable to practise it. ae * Mercury Outboards Do different types of lifejackets and A personal flotation devices (PFDs) offer more or less thermal protection?

Fair Thermal Protection Two types of PFDs offered significant thermal protection to the extent of a 50% to 75°%o increase in predicted survival time. The types were foam vests that possessed good adjustability for close fit to the chest and garment type Flotation Jackets that use buoyancy, and insulating foam between the inner and outer layers of fabric. Good Thermal Protection There are two types of PFDs that make a deliberate attempt to maxt- mize thermal protection.

At a time of critical decision making, alcohol or anything that interferes with one's ability to think should be avoided.

The cause of this "sudden death" is not § clear and a number of different reasons have been suggested. One is a form of cardiac arrest resulting from the increase in heart rate and changes in blood pressure which accompany immersion in cold water, Other possible causes of death are and Motor rentals e Tackle and Bait e Trailer Park eDocking & Storage e Boat Launching Waubaushene, Ont. 538-2285 related to hyperventilation (over breathing), which everyone experiences in response to the shock of cold water. It is possible that ifone had plunged underwater or was in a rough sea that the hyperventilation could Icad to uncontrol- led aspiration (inhalation) of water and a form of drowning. Prolonged hyperventilation can lead to unconsciousness and subsequent drowning. Because panic can magnify any of the above responses, it is important to remain calm and methodical if faced with a cold water emergency. If possible, enter the water gradually, allowing the body to adjust to the changing temperature. Consciously control your breathing as much as possible. The more clothing and insulation your body has, the less will be the initial shock on cntry into cold water. Page 18, Friday, May 21, 1982 ae a ee ERR ce ce
