Re: Safety Freedivers bringing up the BO victims

Now I have seen it one too many times so I must say this:
Rescue-breath is the wrong way to revive a black-out victim at surface. It can actually prolong the time of Black out.
Blow tap talk with increasing intensity is the right way the first 20-30 seconds (maybe more).
One must understand the mind of a blacked out freediver.
The black out comes from lack of oxygen in the brain.
But the reason why a BO victim does not breath at the surface is not due to lack of oxygen in the brain.
The reflex to stay alive includes holding ones breath at surface, since the BO victim does not know that there is air available.
The safetydiver must "talk" to the subconcious of the BO victim (they can still hear and feel). It is about contacting the subconcious with the message that "you are safe".
This is done by touching, holding and specially tapping the cheek and talking to the victim, saing their name.
But the most important thing is the blowing in the face, this is many times better than a rescuebreath. Air on the face causes a reaction to breath.
While a rescue breath might even feel like an "attack". It is scientificly proven that one can not get a laryngospasm to go away by breathing against the epiglottis.
The rescue breath is a anti-rescue breath. If done at a later state - it should be done on a plattform. If water gets down the throat that migth seal a laryngospasm even more.
Some might say: I have revived many freedivers with rescuebreath. Yes that is because rescue breath is better than nothing. If you fidle around with a BO victim long enough they will either realize they are at the surface or the laryngospasm will release itself due to lack of oxygen in the muscle. BTT will be faster.
Stop this rescue-breath nonsense. Or give me arguments why its better than initial and throrugh BTT.
