[SCD-FORUM] 60S RE: Cardiorespiratory arrest and sudden cardiac death. Dr. Sanchez Verduzco

[SCD Symposium]

I can't see hardly any complication, not even semantic, in what we  
consider cardiac arrest or better, cardiorespiratory arrest,  
whichever the cause. We may simply consider that any patient that  
requires cardiorespiratory reanimation is because he/she has: lack of  
effective cardiac output.

>> Dear colleagues,
>> I am writing to this list because I would to have some concepts  
>> clarified to me regarding the subject of discussion.
>> I have looked through several articles, books and journals, and  
>> they are not clear in this sense. For instance: the Spanish  
>> guidelines for CPR mention that there is a very narrow and  
>> arbitrary limit between the concepts of cardiorespiratory arrest  
>> and sudden cardiac death, leaving one for statistic limits, and  
>> the cardiorespiratory arrest as a clinical approach of the problem.
>> My question for the experts:
>> Is there some way of defining both concepts, or do they overlap in  
>> such a way that they can be used without distinction in related  
>> studies and papers?
>> Other authors point out “reanimation from sudden cardiac death”.
>> Could it be reanimation from a cardiac arrest? Is it not death  
>> precisely that, “death”?
>>
>> I hope you can clarify this dilemma for me, and thanking you in  
>> advance,
