Was delivering an AED course today and while doing the BLS part was asked "When someones heart stops, are they more likely to take a breath in or out"? Is there any "rule" or can it be either?? Andy

Don't know but I would not be that concerned if they took a breath in or out as that's the least of their worry (the victims and your students). You may have Agonal breathing following the arrest.
I would say if the cause was sudden CA following MI then breathing in would be most likely. mediaid2010-08-11 22:35:41

To be honest, could be either inspiration or expiration - doesn't matter either way - compressions & AED are what matter!!

You've just died! How many dead people take a breath when they die? Cardiac arrest, no circulation, no blood going to muscles, muscles don't contract, no breath in.

I replied to this a few minutes ago - don't know where that one went. Apologies if somehow it comes up twice
Inspiration is an active process, expiration is a passive process. Therefore it should be an exhalation

Let us not forget that Agonal breathing can occur in up to 40% of cardiac arrests just after the heart has stopped and includes both inhalation and exhalation.
Often described to the ambulance operator as:
Noisy breathing
Gasping breathing
Hardly breathing
and in some cases "Oh Yea, they are breathing."
In the last year two of my First Aiders have found themselves giving CPR to casualties that non First Aiders have described as breathing.

The point is that a casualty can sometimes be seen to be agonal breathing even though the heart may have stopped.
This is often mistaken by members of the public as normal breathing, where as all First Aiders should be able to recognise it for what it is, a recognised sign of Cardiac arrest.

Sorry for the PM didn't notice that i clicked the PM button. EmikoFierros025 says Hi!

At first aid level, pulse check should not be used to determine signs of life. It's too easy to get this wrong, hence it is no longer performed.

I woould also like to add, in response to the comment "when there is pulse would be breathing" that this not necessarily true. When someone stops breathing, their heart will only beat as long as it has a supply of oxygenated blood and that will not be for long if they have already stopped breathing.
