Scuba diving accidents Statistics
Explanation of terms:
- Drowning : Unaccounted for drowning / diver error
- Arterial Gas Embolism: Caused most often by the expansion of respiratory gases during ascent, it also occurs when the breath is held during ascent from a dive, when there is local pulmonary pathology, when there is dynamic airway collapse in the non-cartilaginous airways and if there is low pulmonary compliance, particularly if this is not distributed evenly throughout the lungs.
- Cardiac Incident: Heart attack / stroke
- Trauma: Injury sustained while diving
- DCS: Refers to decompression sickness / illness
- Loss of consciousness: Unexplained loss of consciousness while diving
- Inappropriate Gas: Incorrect gas mix was cause of death
A new report says that common causes of Open-Circuit Recreational Diving Fatalities examined 947 recreational diving fatalities between 1992 and 2003. According to Dr. P.J. Denoble that looking at these cases over a long period of time allowed them to see patterns, not just in the causes of death (COD) but in the events leading up to the deaths of these divers. Drowning was the COD in 70% less of cases, but that proved less important statistically than the disabling injuries that caused the divers to drown, and 88% of the cases involved one of three disabling injuries
How can I be a safer diver?
Over half of these diving accidents were caused by a cardiac incident
or Arterial Gas Embolism. Your heart and circulatory system are more
important in diving than in most sports, so it's a good idea to make
your heart is in good condition before diving.
Before jumping in the water, get yourself heart-smart with the following F.I.T formula to make sure you get the right frequency, intensity and time in your exercise routine.
Frequency: For best cardiovascular fitness, do aerobic exercise 5 to 7 days per week. Walking, jogging, and biking are great outdoor exercises; cardio machines like treadmills, elliptical and stationary bikes are also best ways for indoor routine.
Intensity: Ensure you heart works at the correct intensity during aerobic session. Subtract your age from 220 to find your estimated maximum heart rate in beats per minute (BPM). Your target heart rates should be from 50 to 80% of your maximum BPM. So multiply your maximum heart rate by 0.5, and again by 0.80 to get your target heart rate range. When you do your exercise make sure you check your pulse periodically to ensure your BPM stays within the range.
Time: Each aerobic workout session should last 30 to 45 minutes to get the maximum cardiovascular benefit, but it?s ok to break your sessions into segments. Try two or three 15 minutes intervals with a break in between them.
Always remember the golden rule of scuba diving: Don't
hold your breath!
Scuba diving is still an incredibly safe sport when done properly, with an fatal accident rate of approximately 1 death per 200,000 dives. This would mean to even be inside the chances of having a fatal accident, statistically you'd have to dive 12 times a day, every day, from the age of 18 years old to 65 years old: No breaks!
