Which condition can affect divers?
Many diving accidents or illnesses are related to the effect of pressure on gases in the body;
- Compression arthralgia.
- Decompression sickness.
- Dysbaric osteonecrosis.
- High pressure nervous syndrome.
- Nitrogen narcosis.
- Oxygen toxicity.
Can you scuba dive if you have a heart condition?
In a well-controlled environment (warm water, no wind or current), an individual with coronary disease and good left ventricular function could dive safely with no more than 4 mets of energy expenditure (i.e. 8 mets peak capacity). Improving aerobic capacity after PCI or CABG is also essential to safe diving.
What ailment can severely affect scuba divers?
Decompression sickness: Often called “the bends,” decompression sickness happens when a scuba diver ascends too quickly. Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body’s tissues. This doesn’t cause a problem when a diver is down in the water.
Can you go diving if you have healthy problems?
If your blood pressure is well controlled on your medications and diet, you should be fine to go diving. However, if your blood pressure is not controlled you should work with your doctor to get it under control before you go.
What is the most common injury in scuba diving?
The most common injury in divers is ear barotrauma (Box 3-03). On descent, failure to equalize pressure changes within the middle ear space creates a pressure gradient across the eardrum.
What are 3 common emergencies experienced by divers?
- Arterial Gas Embolism.
- Decompression Sickness.
- Pulmonary barotrauma.
Is it OK to dive with high blood pressure?
Having high blood pressure puts you at increased risk whilst diving. It is a major risk factor for having a heart attack or a stroke, both of which could be fatal underwater. Over time, high blood pressure can damage the blood vessels in the body, and the heart muscle itself.
Does scuba diving raise your blood pressure?
Scuba diving can be a great way to keep fit and provide a workout for your heart. However, diving can have significant effects on the body, including increasing blood pressure, which could pose a risk when diving, or a risk to your health in general.
Is diving good for your heart?
An exciting animal encounter or a strong current can increase the heart rate, but the overall dive experience is relaxing and calming, which reduces stress and anxiety. The lower temperature of the water physically calms the body and the blood vessels resulting in a lower heart rate and lower blood pressure.
Is scuba diving hard on your body?
Scuba diving exposes you to many effects, including immersion, cold, hyperbaric gases, elevated breathing pressure, exercise and stress, as well as a postdive risk of gas bubbles circulating in your blood. Your heart’s capacity to support an elevated blood output decreases with age and with disease.
Can your lungs collapse from diving?
If a diver experiences a pneumothorax while underwater at any considerable depth, it could be fatal. Collapsed lungs that occur for specific reasons, such as trauma or with medical procedures near the lung, are not disquali- fying but require a considerable time of healing before diving.
Can scuba diving damage your lungs?
Can I be seriously hurt while scuba 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.
