Understanding the Impact of Deep Scuba Diving

How deep have you been submerged?” was an inquiry by one of my vast water course. This is a dubious inquiry, one that I don’t care to answer since I expect that my understudies may seek to my most extreme profundity, or more regrettable, endeavor to beat it. A more proper inquiry is, “The means by which deep should scuba divers slide?” Unfortunately, the appropriate response isn’t straightforward- – it relies upon an assortment of variables, for example, breathing gas, encounter level and individual resistance for high incomplete weights of dormant gasses and oxygen.

Contemplations in Determining a Maximum Depth

Decompression Status

The deeper a diver dives, the shorter his no-decompression point of confinement will be. For instance, a diver who plunges to 40 feet can stay at the profundity for 140 minutes (air supply allowing). A diver who drops to 130 feet can remain just 10 minutes at that profundity before amassing such a great amount of nitrogen in his body that he requires a progression of decompression stops in transit up to lessen his danger of decompression affliction. Dropping past 130 feet without decompression dive preparing does not enable a diver much time to make the most of his dive.

Air Consumption

A diver inhales air at the weight of the water around him (encompassing weight). The deeper a diver goes, the more the air he inhales packs (take in more about water weight and diving). At a profundity of 130 feet, a diver devours his air roughly five times quicker than he does at first glance. Divers who anticipate diving to this profundity will find that their dive time is constrained via air utilization. Not exclusively will a diver utilize his air all the more rapidly at more prominent profundities, he will likewise require a huge air save for the long climb from deep dives.


A few gases, such a nitrogen, may cause narcosis in divers at expanded incomplete weights. Each diver will encounter this narcosis in the end, however the beginning of idle gas narcosis differs from diver to diver and from everyday. Be cautioned – regardless of whether you encounter the smashed sentiment of narcosis as charming, it shares a considerable lot of the manifestations of liquor inebriation, for example, hindrance to engine coordination, judgment, and thinking. A few divers even report visual unsettling influences and a skewed feeling of time.

This is certainly not a decent state to be in when deep submerged. A diver ought to gradually expand dive profundities as he picks up involvement and he ought to make certain to make his underlying deep dives (deeper than 60 ft.) with a qualified individual, for example, a guide or teacher who can screen him for indications of narcosis and help him if fundamental.

Oxygen Toxicity

At high focuses, oxygen ends up toxic (oxygen danger), causing shakings, obviousness and even passing. At the point when the recreational profundity rules are taken after, oxygen poisonous quality isn’t a worry for scuba divers. All things considered, this gives divers another justifiable reason not to surpass profundity impediments. The oxygen in air may end up lethal at profundities starting at around 218 feet, and gas blends with high rates of oxygen, for example, enhanced air nitrox, might be harmful at much shallower profundities.

Experience Level

Profundity is a pressure factor in scuba diving. Mentally, deeper dives are distressing in light of the fact that divers are more remote from their leave point. Divers will see their air supply dropping more quickly than at shallower profundities, may see an expansion in breathing opposition and are probably going to encounter some form of gentle narcosis. While deeper dives are much of the time extremely wonderful, have unblemished reefs, and unexpected natural life in comparison to shallow dives, divers should expand their dive profundities mindfully. Making your first deep dives under the supervision of a qualified guide or teacher is constantly prudent.
