## How Fast Should You Ascend When Scuba Diving?
Ascending too quickly while scuba diving can lead to decompression sickness (DCS), a serious condition that can cause a variety of symptoms, including joint pain, fatigue, and shortness of breath. In severe cases, DCS can even be fatal.
The speed at which you ascend is determined by a number of factors, including the depth of your dive, the amount of nitrogen you have absorbed into your body, and your personal fitness level. However, as a general rule, you should ascend no faster than 30 feet per minute (fpm).
If you ascend too quickly, the nitrogen that has dissolved into your tissues will form bubbles as the pressure decreases. These bubbles can then block blood vessels and cause DCS.
The following are some tips for ascending safely:
Ascend slowly and steadily.
Make frequent stops to allow your body to adjust to the decreasing pressure.
Do not hold your breath while ascending.
If you feel any pain or discomfort, stop ascending and contact your divemaster or instructor.
### Symptoms of Decompression Sickness
The symptoms of DCS can vary depending on the severity of the condition. However, some common symptoms include:
Joint pain
Fatigue
Shortness of breath
Dizziness
Nausea
Vomiting
Confusion
Paralysis
### Treatment for Decompression Sickness
If you think you may have DCS, it is important to seek medical attention immediately. Treatment for DCS typically involves recompression therapy, which involves breathing pure oxygen in a pressurized chamber.
### Prevention of Decompression Sickness
The best way to prevent DCS is to ascend slowly and safely. However, there are a few other things you can do to reduce your risk, including:
Staying well-hydrated.
Avoid drinking alcohol before or after diving.
Getting enough rest before and after diving.
Diving within your limits.
### Additional Tips for Ascending Safely
In addition to the tips above, there are a few other things you can do to ascend safely:
Use a dive computer to monitor your depth and ascent rate.
Ascend with a buddy.
Stay close to the surface during your ascent.
Avoid diving in cold water or at high altitudes.
By following these tips, you can help reduce your risk of DCS and ensure that you have a safe and enjoyable dive.
