I know this is not a laughing matter, but I am somewhat bewildered and amused at some of the responses on this thread.
You do realize that having a student make an Ahhhh sound (or any sound at all, for that matter) constricts the airway, right? That would actually increase the chances of an expansion injury, not reduce it. There is no reason to "blow bubbles" or make any sound at all - just maintain an open and relaxed airway, and the increase in gas volume will be eliminated naturally, without any additional effort on the part of the diver (Boyle's Law and all that stuff).We ask the studnet to make an Ahhhh sound and listen for it. It is impossilbe to make the sound and hold your breath.
These two statements contradict each other. If these instructors "should not have been there", but got "rubber stamped anyway", then that is an agency issue, since they created, sanctioned, and supported the process by which it was allowed to happen. Good agencies turn out good instructors, period. Not-so-good agencies can turn out good instructors too, but it is usually not directly the result of anything the agency did. It is more due to the individual instructor taking enough pride in what they do to want to do it better than what the minimum standard calls for.many instructors don't turn out good students and you can't simply generalize it to all [XXX agency] instructors. [...] When I did my IDC/IE, I observed many instructors that should not have been there, but got rubber stamped anyway.
