What health conditions prevent you from diving?

What health conditions prevent you from diving?

Yes. The most dangerous medical problems are barotrauma to the lungs and decompression sickness, also called “the bends.” Barotrauma occurs when you are rising to the surface of the water (ascent) and gas inside the lungs expands, hurting surrounding body tissues.

What happens if a diver goes too deep?

In extreme cases, it can cause paralysis or death if the bubbles are in the brain. Nitrogen narcosis: Deep dives can cause so much nitrogen to build up in the brain that you can become confused and act as though you’ve been drinking alcohol.

What other problems might a deep sea diver face?

Diving does entail some risk. Not to frighten you, but these risks include decompression sickness (DCS, the “bends”), arterial air embolism, and of course drowning. There are also effects of diving, such as nitrogen narcosis, that can contribute to the cause of these problems.

What does a diving medical consist of?

Conduct an examination, including hearing test, visual test, lung test (spirometry), heart trace (ECG), urine analysis and 3 minute fitness test. Initial examination also requires assessing a full blood count, which will be carried out by your HSE Diving Medical Examiner. Examination will last approximately 1 hour.

Can you scuba dive if you have COPD?

Even with the clinical designation of mild there is measurable obstruction beyond what is considered safe among pulmonology experts trained in dive medicine. For these reasons, diving with COPD — even mild COPD — is not recommended.

What are two problems that must be overcome in deep sea diving?

Diving poses two major challenges for air-breathing animals: hypoxia (a shortage of oxygen) and hyperbaria (high pressure at depth).

Can any GP perform a dive medical?

Please note that, in theory, any GP can perform a dive medical. It is up to you who you use, but essentially all we require is a medical certificate stating that you are fit to dive. Please give us a call on 02 8116 1199 if you have any questions.

How long does a dive medical take?

A Recreational Diving Medical costs $121 and will take approximately 1 hour to complete.

Are there any dangers associated with deep diving?

Deep diving involves a much greater danger of all of these, and presents the additional risk of oxygen toxicity, which may lead to a convulsion underwater. Very deep diving using a helium-oxygen mixture ( heliox) carries a risk of high-pressure nervous syndrome.

Why did deep sea diver survive 300ft under water?

The freezing water could have activated his diving reflex which would have slowed his heart and optimised his respiration while under water. Oliver Firth, medical director of the London Diving Chamber, said: ‘It’s staggering that he survived. He should be dead at that sort of depth.

What is deep diving According to Padi and NAUI?

Deep diving is underwater diving to depths beyond first stage diver training. For PADI and NAUI this means deeper than 18 metres (60 feet) and BSAC deeper than 20 metres (66 feet). But in practice deep diving is beyond 30 metres (98 feet) when divers can experience nitrogen narcosis. What is deep diving according to PADI?

Why is decompression so important in deep diving?

The most important procedure for dealing with physiological problems of breathing at high ambient pressures associated with deep diving is decompression. This is necessary to prevent inert gas bubble formation in the body tissues of the diver, which can cause severe injury.

What happens to your body when you go deep sea diving?

Diving medical technicians place you in a diving chamber and increase the pressure until it equals the pressure at which you were diving. You may breathe pure oxygen during the treatment. When you dive, the nitrogen forced from your circulatory system by the water’s pressure forms bubbles that gather in your joints.

Are there any medical problems associated with scuba diving?

SCUBA diving is inherently risky, as participants are submerged in a hostile environment where they are at risk for potential life-threatening problems. Decompression syndrome (DCS), hypothermia, drowning, barotrauma, immersion pulmonary edema, and gas embolism are important medical complications of diving.

What do you need to know about medical examination of divers?

The medical examination of divers requires detailed background knowledge in order to be able to make a reasoned judgement of the fitness of an individual to dive. Such knowledge is comprised of not only a sound understanding of diving physiology but also an appreciation of the different aspects of recreational and professional diving.

What are the symptoms of DCS in diving?

The onset of symptoms within 10 minutes is more suggestive of gas embolism, whereas DCS tends to present after 10 minutes. Symptoms of DCS (listed in decreasing order of overall prevalence): Barotrauma to the ears, sinuses, and lungs presents with local pain or shortness of breath during the dive itself.
