Scuba Diving emergency, out of air in a fast current! St. Lawrence River

The high pressure line came off of the SPG guage, causing a rapid loss of air. After 2 breaths no more air was coming into the regulator. The third breath was water! This occurred in a high current area between the wreck A E Vickery and the dive boat. An emergency ascent was the last resort due to the heavy traffic of small boats and sea faring ships. The buddy system works and so does being calm! Man a lot of you must not read this part. No more air was coming out of primary regulator... about a minute later in the video I try to use the octo and it is airless too.
