, Author of Cannabis Pharmacy. 1  There are several problems with chewing/dipping cannabis. First, cannabis, in its raw herbal form, can host a wide variety of microbes including e coli and salmonella, both of which can present a health risk.
Oxygenation and ventilation: Once the position and seal are obtained, bagging can commence. The rate of ventilation for an adult is 10-12 breaths per minute or, approximately 1 bag squeeze every 5-6 seconds.4 The bag should be depressed for a full 1-2 seconds and then released.
When talking to people about first aid and CPR in particular, I find a lot of confusion centred around the ratio of compressions to rescue breaths. That is, how many times should you press down on the chest and how many times should you give mouth to mouth breaths.This is really not too surprising, as it has been subject to change over the years. I started to learn first aid in the winter of 1971/72, at the tender age of 8.f, however, you have help, then you should give 5 compressions to 1 breath. In my 1979 book, I am told that the correct ratio is 5 to 1, with or without help, but by the second half of the eighties we are back to 15 to 2 on our own or 5 to 1 with help.
