  1. this was amazing! so clear, coherent and methodical. (and i especially appreciated the historical context. absolutely fascinating.)

    i am training in EMT-B and i found this very informative.

    i just wanted to clarify something. your main point is that the underlying cause of cardiac arrest, in a drowning victim, stems from a lack of oxygen (ie respiratory failure) as opposed to cardiac failure.

    are you therefore suggesting that there be a different ratio then suggested (at least in NY) 30:2 compression to ventilation ratio? or are you just emphasising the importance of ventilating?

    all the best,

  2. Jeffrey:

    Thank you so much for your comments. Our main point is that ventilations cannot be left out of the CPR algorithm. This blows most peoples’ minds because they know how much “compression-only CPR” has been pushed. It is just important to know that this technique is focused on primary cardiac events. The only recommendations we can really make it to follow whatever the current, region-specific algorithm is for compression and ventilation CPR (Currently 30:2 in the US). If I am on scene and participating in 2-person CPR, I would personally try and give some ventilations during the compressions to increase minute ventilations, but this can often be difficult with compressions in progress. If an advanced airway is in place, then definitely give ventilations more often (every 6 seconds). Hope this helps.
