## What is DCS Scuba Diving?
DCS stands for Decompression Sickness, also known as “the bends”. It is a serious diving injury that can occur when a diver ascends too quickly from a dive, causing nitrogen bubbles to form in the body. These bubbles can block blood flow to vital organs, causing tissue damage and potentially life-threatening consequences.
Causes of DCS
DCS is caused by the formation of nitrogen bubbles in the body. Nitrogen is a gas that exists in the air we breathe. When we breathe compressed air underwater, the nitrogen in the air is absorbed into our bloodstream. When we ascend, the nitrogen gas is released from our bloodstream and forms bubbles. The faster we ascend, the more nitrogen bubbles are released and the greater the risk of DCS.
Symptoms of DCS
The symptoms of DCS can vary depending on the severity of the injury. Mild DCS may cause joint pain, skin rash, and fatigue. More severe DCS can cause more serious symptoms, such as:
Paralysis
Numbness
Dizziness
Nausea
Vomiting
Confusion
Seizures
Unconsciousness
Treatment of DCS
DCS is a serious medical emergency. If you suspect that you or someone else has DCS, call for emergency medical help immediately. Treatment for DCS typically involves recompression therapy, which involves placing the injured diver in a chamber and increasing the pressure to help dissolve the nitrogen bubbles.
Preventing DCS
There are several things you can do to prevent DCS, including:
Ascending slowly from dives
Making safety stops at regular intervals during your ascent
Using a dive computer to monitor your depth and ascent rate
Staying well-hydrated
Avoiding alcohol and caffeine before and after dives
DCS is a serious diving injury that can be prevented by following safe diving practices.
### Types of DCS
There are two main types of DCS:
Type I DCS is the less severe form of DCS. It typically causes joint pain, skin rash, and fatigue.
Type II DCS is the more severe form of DCS. It can cause more serious symptoms, such as paralysis, numbness, dizziness, nausea, vomiting, confusion, seizures, and unconsciousness.
### Risk Factors for DCS
The following factors can increase your risk of DCS:
Diving at greater depths
Diving for longer durations
Ascending too quickly from dives
Making multiple dives in a short period of time
Being overweight or obese
Being dehydrated
Consuming alcohol or caffeine before or after dives
### How to Prevent DCS
There are several things you can do to prevent DCS, including:
Ascend slowly from dives. The slower you ascend, the more time the nitrogen gas in your bloodstream has to dissolve safely.
Make safety stops at regular intervals during your ascent. Safety stops are short pauses that you make at specific depths during your ascent to allow the nitrogen gas in your bloodstream to dissolve more gradually.
Use a dive computer to monitor your depth and ascent rate. A dive computer can help you track your depth and ascent rate and ensure that you are ascending safely.
Stay well-hydrated. Dehydration can increase your risk of DCS. Drink plenty of fluids before, during, and after dives.
Avoid alcohol and caffeine before and after dives. Alcohol and caffeine can both dehydrate you and increase your risk of DCS.
