## How to Decompress After Scuba Diving
Scuba diving is a great way to explore the underwater world, but it’s important to decompress properly after a dive to avoid decompression sickness (DCS). DCS is a serious condition that can occur when nitrogen bubbles form in your body during or after a dive. These bubbles can block blood flow and cause pain, paralysis, or even death.
The risk of DCS is greater the deeper you dive and the longer you stay down. However, even shallow dives can cause DCS if you don’t decompress properly.
There are two main types of decompression:
Controlled decompression: This type of decompression is done using a dive computer or dive tables. It involves making a series of stops at different depths on your way back to the surface. This allows the nitrogen in your body to slowly dissolve and be released without forming bubbles.
Uncontrolled decompression: This type of decompression is done without using a dive computer or dive tables. It involves simply ascending to the surface at a slow rate. This is not as safe as controlled decompression, but it can be done in an emergency if you don’t have a dive computer or dive tables.
## How to Decompress Using a Dive Computer
If you are using a dive computer, it will automatically calculate the decompression stops you need to make. All you need to do is follow the instructions on the computer.
Here are some general guidelines for decompression using a dive computer:
Ascend at a rate of no more than 30 feet per minute (9 meters per minute).
Make a safety stop at 15 feet (4.5 meters) for 3 minutes.
If you are diving deeper than 100 feet (30 meters), you will need to make additional decompression stops.
## How to Decompress Using Dive Tables
If you are not using a dive computer, you can use dive tables to calculate the decompression stops you need to make. Dive tables are available online and in dive shops.
To use dive tables, you need to know your maximum depth and your bottom time. Your maximum depth is the deepest depth you reached during your dive. Your bottom time is the amount of time you spent at your maximum depth.
Once you know your maximum depth and your bottom time, you can look up the corresponding decompression stops in the dive tables.
Here are some general guidelines for decompression using dive tables:
Ascend at a rate of no more than 30 feet per minute (9 meters per minute).
Make a safety stop at 15 feet (4.5 meters) for 3 minutes.
If you are diving deeper than 100 feet (30 meters), you will need to make additional decompression stops.
## How to Decompress Uncontrolled
If you do not have a dive computer or dive tables, you can decompress uncontrolled. However, this is not as safe as controlled decompression.
To decompress uncontrolled, simply ascend to the surface at a slow rate. Do not ascend faster than 30 feet per minute (9 meters per minute).
Make a safety stop at 15 feet (4.5 meters) for 3 minutes.
If you feel any pain or discomfort during your ascent, stop and ascend more slowly.
## Symptoms of Decompression Sickness
The symptoms of decompression sickness can vary depending on the severity of the condition. Some common symptoms include:
Pain in the joints, muscles, or skin
Numbness or tingling in the hands or feet
Weakness or paralysis
Dizziness or nausea
Shortness of breath
Confusion
Loss of consciousness
## Treatment for Decompression Sickness
If you think you may have decompression sickness, it is important to seek medical attention immediately. Treatment for DCS may include:
Oxygen therapy
Hyperbaric oxygen therapy
Medications
Surgery
## Prevention of Decompression Sickness
The best way to prevent decompression sickness is to decompress properly after each dive. Follow the guidelines in this article to help reduce your risk of DCS.
### Tips for Preventing Decompression Sickness
Dive within your limits.
Ascend slowly and make safety stops.
Stay hydrated.
Avoid alcohol and caffeine before and after diving.
Get a dive physical before diving.
Tell your dive buddy if you are not feeling well.
By following these tips, you can help reduce your risk of decompression sickness and enjoy scuba diving safely.
