    I've got an my old MET at work, I've had it knocked off bikes a few times without damage, will drop it from 2m and see what happens.

    Any helmet dropped from 1/2 meter with bits falling off is not fit for purpose imho..

    To be quite honest if I was in trouble, I would rather people didn't bother discussing whether it was a heart attack, or cardiac arrest

    Just get on with it!

    srw It's a bit more complicated than that...

    Found something which appears to be quite interesting.

    Full disclaimer - I'm not a medic. I may be misinterpreting this. But it seems to say that head injury results in breathing stopping. And (based on a rat model) you need a really substantial blow to the head - one inducing a pressure of 3 atmospheres inside the skull - to stop breathing for long enough to cause cardiac arrest.

    Watch out for that car's driver though. Nobberissimo at the wheel, more suited to an Audi.

  10. You need to search more "diligently" even your "diligent searching" on head whacks causing heart attacks failed to turn up countless cases of people developing blood clots, as a consequence, which travel to the heart's blood vessels, and cause an actual heart attack, which may or may not ( but often does ) lead to cardiac arrest. Heart attacks don't always lead to cardiac arrests, if you spot the symptoms of the heart attack early enough, and act on it, the cardiac arrest can often be avoided. There's so much else wrong with what you typed, I would need about a week to address it all. I can't be bothered. I would suggest that you go and get some first aid qualifications, then come back, when you've got more of a clue. Even the basic 3 hour EFAW etc. course would do.

    Had a conversation with one of my mothers friends yesterday, she was telling me about a club comrade of her son in law (still with me?) he apparently had a collision with a Deer. He wasn't wearing a helmet and has suffered quite severe head injuries. The general jist was that clearly a helmet would have helped him. I found myself explaining that helmets are quite thin and weak and in certain countries the incidence of head injuries hasn't dropped with the compulsive use of helmets, my mothers friend had to agree and was surprised.
    A helmet may have helped him, who knows, I just felt I had to balance the argument. What's happening to me :crazy:?

    I still "mostly" wear my own helmet by the way :tongue:.

    You don't know much physiology, do you?

    Firstly, for a brain injury to cause cardiac arrest, severe damage must be done to the brain stem. Damage severe enough to be highly likely to lead to death by itself. Secondly, the idea that unconsciousness inevitably leads to cradiac arrest is also untrue. Unconsciousness can lead to respiratory arrest through obstruction to the unguarded airway. This is why the very first thing taught on a first aid course is the recovery position and the importance of preserving the airway.

    This is just nonsense.

    A heart attack is caused by a blockage in the arteries in the heart muscle, thereby depriving part of the muscle of blood flow. Injury is unlikely to generate clots that reach tthe systemic circulation. Clots may form afterwards through the enforced inactivity - this is deep vein thrombosis. And clots that do form won't reach the heart - they'll be caught in the capillary beds of the lungs, which is pulmonary emobolism. This in itself is a life threatening emergency which will not be helped by treating it as a heart attack. It also has nothing whatever to do with head injury.

    I hope you're not planning on getting any medical qualifications.
