Why don't we emphasize cesa more??

Yea this boat sank before it left the dock. Funny question though. Kinda like asking why we don't teach airbag deployment in driver's ed.

I won't speak for any other instructors, but I am required to teach CESA, per PADI standards. Covered in the pool and OW. Also the way I teach it is controlled and you are not gonna race for the surface. First off you would be dragging me along cause I have ahold of ya, but I am also holding an upline that I will use to prevent that and then you will have to do it again and make my ears unhappy. So I really try to explain it enough before we descend.

I prefer my students humm so gently that I can not hear it over our combined bubbles, that's why the other hand is nearly touching the reg. Seems that if I could hear the humm I'd easily see the bubbles and the student would likely run out of air too soon for deeper depths. I wish we did blow and go from 30', 20' is much too easy.

I am with you on this pir8. NAUI follows that standard as well. I have no idea where nemrod is getting his facts from, but a horizontal cesa in confined water and a vertical cesa in open with the instructor holding a line and the student is in the minimum standards for certification.

PADI allows the CESA to be done from anywhere between 20 and 30 feet. Like you, I prefer 30.

 

[pir8]

The platforms that I use are at 30ft.

A
Are air embolism occurring because of preexisting pathologies in their lung, or is it that we, as a group, are not practicing cesa enough??

I'd argue the other way. Why in this day and age are we still teaching CESA at all ?
One of my agencies does, the other doesn't

Personally i think its a useless relic of a skill with no purpose or place in modern diving. Equipment and training have moved on.

Are you arguing that the 29 people who died in a year from OOA situation died with embolism because they have preexisting pathologies??

I still wonder if they remembered their CESA as they ascended?

No. I'm arguing that their training and or skills were inadequate forcing them to "bolt n pray". Had they acted properly they wouldn't have been in the position to need it.

They weren't carrying a redundant air source, were unable to share air with a buddys octopus or buddy breath or didn't have a buddy at all.

That's at least 3 things they should have been trained to do and capable of doing. If they screwed those 3 up why do you think that they'd be competent to perform a 4th skills ? Chances are they'd screw that up to.

I just was PADI certifid last Oct. and my son just finished his confied dives and the taught us both cesa
