2 Google gave hits when seaching for ”drowning while diving” in Mars After drowning, heart problems constitute the second most common cause of death among divers.

3 Recreational diving, also called sportsdiving or amateur diving, is either -Breathhold diving, also called apnea diving -Or SCUBA (Self Contained Underwater Breathing Apparatus) Sometimes difficult to distinguish in statistics and reports. ”Anyone dressed in black in water is a diver.”

4 HLR Om Drunkning Tylösand 3-4 juni 2014 How dangerous is it to dive? Data on fatality risks from 1 out of every 211,864 dives ends in a fatality (DAN 2010) 1 out of every 126,626 marathon runners died of sudden cardiac arrest while running a marathon between (National Safety Council) 1 out of every 116,666 skydives ended in a fatality in 2000 (United States Parachuting Association).

8 Diving Fatality Data (www.divingmedicine.info) In the ANZ survey in half the deaths (56%), critical events developed when the diver was either running low or was out-of-air (LOA, OOA). When equipment was tested following death, few victims had an ample air supply remaining. The DAN survey found 41% in this situation. HLR Om Drunkning Tylösand 3-4 juni 2014

15 Two types of oxygen equipment for 100% oxygen breathing. Both contain 1000 NL of oxygen and have an outlet for a free-flow mask.

16 HLR Om Drunkning Tylösand 3-4 juni 2014 From 2010 the European Resuscitation Council recommends ventilation to be started in water. (Soar J et al in Resuscitation. 2010;81: ) From Diving and Hyperbaric Medicine, June 2013 ”Rescue of drowning victims and divers: is mechanical ventilation possible underwater? A pilot study” The answer is: No The reason is: The breathing valve is not built to deliver the pressure required for inflation of the immersed lung because the exhalation valve opens.
