This new method looks interesting and I hope to see further exploration of it.

Various tidbits:

- doctors provide some of the worst CPR I've ever seen

- not too many people mention "time to advanced life support (ALS)" in their CPR success rate discussions. It is very rare for CPR alone to yield a spontaneous return of circulation

- survival rate from cardiac arrest induced by trauma (bleedout) is just about 0% no matter what you do

- doing rescue breathing on strangers without a barrier is insane

- be trained & equipped to do rescue breathing because it is a valid and valuable skill in many situations that have nothing to do with diseased hearts
