## How to Prevent Oxygen Toxicity in Scuba Diving
Oxygen toxicity is a condition that can occur when a scuba diver breathes in too much oxygen. It can cause a variety of symptoms, including nausea, vomiting, seizures, and even death.
The risk of oxygen toxicity increases with the depth of the dive and the length of time the diver is exposed to oxygen. Divers who breathe pure oxygen at depths greater than 66 feet (20 meters) are at risk of developing oxygen toxicity.
There are a number of things that divers can do to prevent oxygen toxicity, including:
Using nitrox: Nitrox is a mixture of oxygen and nitrogen that contains less oxygen than pure oxygen. Nitrox can be used at greater depths than pure oxygen without increasing the risk of oxygen toxicity.
Limiting dive time: The longer a diver is exposed to oxygen, the greater the risk of developing oxygen toxicity. Divers should limit their dive time to no more than 60 minutes at depths greater than 66 feet (20 meters).
Ascending slowly: When a diver ascends from a deep dive, the pressure on their body decreases. This can cause the nitrogen in their body to come out of solution and form bubbles. Bubbles can block blood flow and cause decompression sickness. Divers should ascend slowly from deep dives to allow the nitrogen in their body to dissolve back into solution.
Drinking plenty of fluids: Drinking plenty of fluids helps to prevent dehydration, which can increase the risk of oxygen toxicity.
Being aware of the symptoms of oxygen toxicity: Divers should be aware of the symptoms of oxygen toxicity and should stop diving if they experience any of these symptoms.
Symptoms of oxygen toxicity
The symptoms of oxygen toxicity can vary depending on the severity of the condition. Mild symptoms include:
Nausea
Vomiting
Dizziness
Headache
Twitching
Muscle cramps
Severe symptoms include:
Seizures
Unconsciousness
Death
Treatment for oxygen toxicity
The treatment for oxygen toxicity is to stop breathing oxygen and to breathe air or nitrox. The diver should be taken to the surface and given oxygen by mask. In severe cases, the diver may need to be placed in a hyperbaric chamber.
Preventing oxygen toxicity is essential for scuba divers. By following the tips in this article, divers can reduce their risk of developing this condition.
Additional tips for preventing oxygen toxicity
Use a dive computer to monitor your depth and dive time.
Dive with a buddy and stay close to each other.
Be aware of the symptoms of oxygen toxicity and stop diving if you experience any of these symptoms.
Get regular medical checkups to make sure you are healthy enough to dive.
By following these tips, you can help to prevent oxygen toxicity and enjoy safe and fun dives.
