Question: Any docs out there see peripherial cyanosis before cardiac arrest!?
Answers:
I have to say I disagree with the previous answerer because your question did not bring up CHF, as he elaborated on!. Almost all who go into cardiac arrest for any reason show some signs of peripheral cyanosis first!. Not all, but most!. FYI: it's not doctors who usually are the first responders, or the ones who find people in cardiac arrest!. It's the clinicians at the bedside--predominantly nurses!. Doctors are relative late comers to cardiac arrest scenes, as a rule!. They run to the scene after the nurse has found the patient in cardiac arrest, called the code and started the resuscitation process!.Www@Answer-Health@Com
i think its important to understand why heart attacks occur in the first place and then you may understand a little better!. although the second answer may be evidently from a nurse! from a physiological point of view, it doenst make sense for peripheral cyanosis to precede a heart attack and if this nurse is under that impression then perhaps he or she is wrongly misdiagnosing it! heart attacsk occur because part of the hearts blood supply is lost and therefore the heart cells die!. this loss of supply occurs because of plaques in arteries full of cholesterol rupturing and therefore this means that it is a SUDDEN event!.
to answer your question, peripheral cyanosis is not really seen at all and to be honest neither is central cyanosis because if the patient dies after the heart attack, cyanosis cant really be diagnosed in a dead patient!
if you remeber that the heart attack evolves very quickly and is a central event then there is no logical reaon why a patient would be centrally cyanosed!.
peripheral cyanosis is a situation where oxygenated blood is not reaching the peripheries usually due to obstruction of some kind of vasoconstriction of the arteries supplying the extermities and therefore on that theory patients would only be peripherally cyanosed after, if at all, a heart attack!.
the commonest example of peripheral cyanosis is when you are cold, your hands and so get cold!. your body stops circulating blood to these' non essential' parts to conserve heat!.Www@Answer-Health@Com

Cyanosis does occur on account of heart failure!.
But not peripheral cyanosis!.
The sort of cyanosis in heart failure that occurs is central!. i!.e!. the mucosa, the lips, tongue, inner oral cavity, etc!.
But in my opinion I doubt cyanosis is a prelude to cardiac arrest, as breathlessness and chest pain shall occur first!.Www@Answer-Health@Com
