There are many things about scuba diving that one needs be careful about and should be well trained to tackle them. That is why there are a number of centers that offer you a proper scuba diving course.
And it mandatory to have certified with the diving course otherwise you are not allowed to dive in the water on your own. And there are valid reasons for this. No matter how far you go whenever you ascend back your way you would get bends. So the more realistic question to answer would be how deep can one dive without getting decompression stops. Decompression that causes bending depends upon the level of depth you dive deep to and the time you stay in the chosen depth. The general guideline is as longer or deeper you dive the more chances of needing decompression stops increases.
You will need to check your air consumption during the time you need to decompress while you are at a stop. So, with that, I hope it is all clear now that what is bending?
What causes bending? How far can you go with respect to the depth of the water before getting bends? What do you need to do to prevent bending while diving? I wish you all a happy and adventurous diving experience ahead. David Griffiths told the Australian and New Zealand College of Anaesthetists conference in Brisbane that it was possible to get decompression sickness diving in sea water less than 10 metres deep.
One diver in 10 who suffered the bends was in this category. One diver got the bends - a painful condition caused by gas bubbles forming in the bloodstream - from diving in water less than four metres deep. Dr Griffiths said that a study of cases showed at least 35 had dived in less than 10 metres of water. Those who repeatedly ascended, did hard work underwater, or drank alcohol afterwards were most at risk.
Other dives had multiple ascents and descents. For example, one diver dived to twenty-five feet for 50 minutes with four ascents, twenty-three feet for 35 minutes with four ascents, and six feet for minutes with more than ten ascents. The shallowest dive implicated in a multiple series was six feet.
Two scientific divers did 19 dives to 33 feet for a total bottom time of four hours. Two divers had 20 ascents in a foot dive. One diver had 30 dives over three days and noticed symptoms of a fuzzy head and general tingling six minutes after his last dive. He required eight treatments before he could be discharged from care.
Limb pain was the most common symptom, reported by 36 divers. Paraesthesia pins and needles was reported by at least ten divers, and headaches, fatigue, lightheadedness, and weakness were the next most common problems.
Six divers reported neurological symptoms and five reported general unwellness. Overall the symptoms were milder than those for divers who had been to deeper depths. Most divers were treated initially using U. Navy treatment table 6, a four-hour minute table, and most required three or four follow-up treatments. In the multiple dive cases, several risk factors were common.
Twenty-nine divers had more than two dives in one day with one ascent per dive, while six divers did only one dive but had multiple ascents.
Seven divers did more than one dive and more than one ascent per dive, and four divers had only dived in a swimming pool but had done many ascents. Some divers also undertook their multiple exposures by going progressively deeper, a well-known risk factor. About a third of the DCI cases were either instructors or students doing multiple training ascents.
