What are the two golden rules when scuba diving?
If you had but 30 seconds to teach someone to scuba dive, what would you tell them? The same thing Mike did — the Golden Rule of scuba diving. Breathe normally; never hold your breath. The rest, in most cases, is pretty much secondary. 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.Individuals should not dive if they have cardiac disease that might result in incapacity underwater (e. IPO (e. DCS (e.If you had but 30 seconds to teach someone to scuba dive, what would you tell them? The same thing Mike did — the Golden Rule of scuba diving. Breathe normally; never hold your breath.

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.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.
Who is not allowed to scuba 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. 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).Scuba diving typically involves moderate intensity physical activity, but situations can occur that require high-intensity activity. In addition, scuba diving challenges the cardiovascular system in a variety of ways that may be life-threatening for individuals with heart disease or a low capacity for exercise.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.Hypertension may be aggravated by immersion and is associated with endothelial dysfunction and increased cardiovascular risk. This may increase the susceptibility to diving related illnesses and this is indeed observed in accident statistics. A specific concern is an increased risk for immersion pulmonary oedema.
What is the safest depth to scuba dive?
For most recreational scuba divers, the safe limit is around 130 feet (or 40 meters). However, some divers go well beyond that. Welcome to the world of technical diving: a more advanced form of scuba that takes you deeper into caves, shipwrecks and other underwater landscapes. It’s rare, but the bends can occur at 10–20 feet (3. The bends generally aren’t a concern unless you go deeper than 30 feet (9.Although some professional divers can enter the water safely from more than 100 feet, chances are good that you’re not a trained professional, and all jumps — even those from a low height — risk serious injury or death.
Why is it not recommended to scuba dive?
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). Because excess nitrogen remains dissolved in the body tissues for at least 12 hours after each dive, repeated dives within 1 day are more likely to cause decompression sickness than a single dive.
