I have been attending courses lately to update some of my first responder skills. I have been told by some that when they recertified in CPR they were no longer taught to apply breaths, just compressions. I have been told by others that applying breaths is still being taught. The information is coming from police, nurses, firemen, one person who works for American Red Cross, and COVID-19 has nothing to do with the way they were trained. Opinions are 50/50 on the topic.

What have you learned lately? When you took a CPR course or recertified, did the instructor(s) teach you to apply breaths or not? If no rescue breathing is recommended, what was the rationale behind not applying breaths between sets of compressions? What state do you live in? Is this regional or something that will be phased in nationwide?
