Many thanks for posting this. It reminded me of a similar experiece about 5 years ago.

We were diving in a remote location at altitude about 9 hours drive from the nearest chamber. Our last dive was 90-100m for 35 minutes with about 3.5 hours in the water. The shape of our profile was similar to yours but with more deep stops.

About 10-15 minutes after hitting the surface, my buddy complained of a sore shoulder. Due to the remoteness, we decided to assume it was a type 1 bend coming on, so before he got out of his kit, we strapped a fresh oxygen bottle to him and got a support diver to take him down to 9m for 20 mins, then 6m for 20, then 3m for 20. There was a complete resolution of symptoms.

This was the sixth day of diving at this location with each dive getting progressively deeper. It also involved carrying a lot of kit down to the waters edge daily. We put the hit down to the build-up over the 6 days, the hard work each morning and evening getting bottles in and out and just a stressed shoulder!

Best,
John.

This is the dive profile that bent a diver. The diver came out feeling very week, vomiting, peeing a lot and with red spots all over the legs.

Attachment 135

After an hour on Oxygen the symptoms eased up but now there was pain and a numbing feeling starting in the legs. The closest recompression chamber was 7 hours away and with the prevailing sea and wind conditions it might have been more. So we opted for in-water recompression. Below is the profile for the in water recompression. All of it was done on 100% pure oxygen.

Attachment 133

After this all the symptoms went and the diver was fine although fatigued and needing lots of sleep. We contacted the chamber doctor informed him of what we had done and he said there is no need to bring the diver in for a check up but we had to wait 48 hours before the diver can dive again. Two days later he/she was diving again.
