What are the medical requirements for diving?
Your respiratory and circulatory systems must be in good health. All body air spaces must be normal and healthy. A person with coronary disease, a current cold or congestion, epilepsy, a severe medical problem or who is under the influence of alcohol or drugs should not dive. Respiratory and cardiovascular systems should be in good shape. All body airspaces must be normal and healthy. A person with heart trouble, a current cold or congestion or who has epilepsy, asthma, a serious medical problem, or who is under the influence of alcohol or drugs, should not dive.Your respiratory and circulatory systems must be in good health.

Divers drown due to running out of air, panic, lack of training, unrelated health problems that cause unconsciousness and equipment failure. As you know humans are built to breathe only air. Inhaling water can become deadly very quick.Diving compressed gases (ie, scuba diving) can lead to two very serious medical conditions: Decompression Sickness (DCS), otherwise known as “the Bends,” and Pulmonary Over-Inflation Syndrome (POIS).
What is the medical condition for diving?
Disorders particularly associated with diving include those caused by variations in ambient pressure, such as barotraumas of descent and ascent, decompression sickness and those caused by exposure to elevated ambient pressure, such as some types of gas toxicity. Among older divers and those with underlying cardiovascular risk factors, these physiologic changes increase acute cardiac risks while diving. Additional scuba risks, as a consequence of physical gas laws, include arterial gas emboli and decompression sickness.Never hold your breath. This is undoubtedly by far the most crucial of all safety rules for diving because failure to adhere could result in fatality. If you hold your breath underwater at the depths at which scuba divers reach then the fluctuating pressure of air in your lungs can rupture the lung walls.The most frequent known root cause for diving fatalities is running out of, or low on, breathing gas, but the reasons for this are not specified, probably due to lack of data. Other factors cited include buoyancy control, entanglement or entrapment, rough water, equipment misuse or problems and emergency ascent.However, SCUBA diving can also lead to decreased lung function due to factors such as hyperoxia, development of decompression gas bubbles, hypothermia, and mouth breathing with dry, cold, compressed air. These factors can trigger airway damage, leading to small airway obstruction (Skogstad et al.Prolonged dives will nonetheless lead to decreased arterial oxygen saturation, eventually impairing normal brain function, which may result in hypoxic syncope, also called blackout (Craig 1961). Without assistance, drowning will likely occur.
What is HSE diving?
The HSE Scuba qualification is the first rung of the ladder in the commercial diving world and is a must for anybody looking to dive in the media, scientific, archaeological or shellfish industries . The HSE scuba qualification is also required before commencing the Surface Supplied course. To prevent decompression sickness, divers must adhere to decompression procedures, which involve ascending slowly. Recreational scuba diving organizations typically limit recreational dives to a maximum depth of 40 meters (130 feet) to ensure the safety of divers without requiring complex and specialized training.EN 14153-2/ ISO 24801-2 Recreational diving services – Safety related minimum competence requirements for the training of recreational scuba divers – Part 2: The level 2 Autonomous diver has sufficient knowledge, skill and experience to make dives, in open water, which do not require in-water decompression stops, to .When a diver swims to the surface too quickly (a rapid ascent), the nitrogen can form tiny bubbles in the blood and/or body tissues, causing decompression sickness (DCS). DCS may occur even if a person dives within the limits of their dive computer or decompression tables and even if they complete a safety stop.Unfortunately, COPD is a contraindication to diving for several reasons. With COPD, there are abnormal enlargements of the air spaces in the lungs and destruction of the air sac (alveoli) walls, reducing their elasticity. The alveolar walls are normally elastic like a balloon.
