If there are two words divers cringe at hearing, these are “the bends.” Equally scary: rds divers cr(feeling out of breath) or “the staggers” (loss of balance). Skin rashes, prickly sensations on the skin, and aching joints after a dive are also a cause concern for divers.
These symptoms all point to decompression illness (DCI), which happens when divers ascend too fast that the nitrogen and other dissolved gases in our body expand too quickly causing air bubbles to form in the body.
Thanks to dive computers, very few divers experience decompression illness these days. The good news is there’s very little risk of DCI if you follow your dive computer and control your ascent. Still, it’s still helpful to know what to do if you or another diver experiences DCI symptoms. DCI is easily preventable and definitely treatable if recognized early on. Here’s what you want to watch out for:
Symptoms of Decompression Illness
· Joint or skeletal pain
· Numbness or neurological problems
· Motor weakness
· Impaired mental status or amnesia
· Dizziness, headache or lightheadedness
· Swelling or skin rashes
· Breathing difficulties
· Chest pain
· Paralysis, especially on one side of the body
In extreme cases DCI symptoms may show up during the dive. However, often they only develop a few hours after the dive. In either case, fast action and first aid can make a difference.
First Aid for Decompression Illness
If the diver is not responsive, or if a diver reports symptoms of DCI, immediately send for medical help. Lie them down on the left side of the body, supporting the head, making sure his or her airways are open and they are able to breathe. Put them on 100% oxygen, keep them warm and ensure they rest until help arrives. Someone who has had symptoms of DCI should not be allowed to get up and walk around, even if they feel better.
Monitor the diver as you wait for help. You can also make a record of the dive details and symptoms reported. Under no circumstances should you try to correct DCI by re-submerging.
PADI (Professional Association of Diving Instructors) and DAN (Divers Alert Network) have a great resources for immediate first aid.
Tips for Preventing Decompression Illness
You can keep yourself safe by:
· Planning a slow and controlled ascent
· Observing the 3-minute safety stop at 5 meters
· Staying within recreational dive limits
Alcohol, altitude, and strenuous exercise can contribute to DCI. It’s best to avoid these three right after diving.
