Decompression Recovery

Almost half of those who are treated with hyperbaric oxygen therapy have some neurological symptoms or pain for several days or weeks after hyperbaric therapy was completed. On average, 16 percent of injured divers will still have symptoms for up to three months after they have been treated.

DAN was contacted by a diver who had received eight hyperbaric treatments for decompression sickness six weeks ago. He was in good physical shape and an hour after diving he experienced numbness and tingling in his left arm, hand, leg and foot and felt very weak and fatigued. At the end of his treatments all his symptoms had alleviated and four days later he flew home without issue. However, he reported that in the last two weeks he had noticed a return of some of the tingling in his left arm and foot that comes and goes but doesn’t completely go away. He was wondering if this was a normal side effect of decompression illness and whether he should seek further recompression. Continue reading “Decompression Recovery”

Safety is in the Air – DAN AP Air Quality Campaign Launch

After the relatively recent death of a scuba diver, it was found that the level of Carbon Monoxide (CO) in his tank was 450 times above the accepted limit. This has prompted DAN AP to launch a safety and awareness campaign, the main goal of which is to prevent people from diving with contaminated breathing gas in the first place.

He had filled his tank from a compressor which had not been properly maintained or regularly tested. As a result, the air being supplied was found to be very high in Carbon Monoxide (CO) levels.

Getting “Dive Season” Fit

Fitness is not only a product of a healthy lifestyle, but also a function of how we address health issues. Lack of fitness poses two risks in scuba diving: what we assume ourselves; and the degree of risk to our buddies and potential rescuers.

Lack of fitness poses two risks in scuba diving: the first risk is what we assume ourselves; the second involves the degree of risk to our buddies and potential rescuers.
