I went on a First Aid refresher recently and was told that the Resuscitation Council are introducing changes to the approved method of CPR. There will no longer be any requirement to do the mouth to mouth. The theory is that chest compressions alone will cause the lungs to deflate and by virtue of air pressure, they will fill again once the compression is complete. As much oxygen will get into the lungs, due to the fact that deoxygenated air isn't being breathed into the patient. The idea is that people who have a fear of mouth to mouth (and who could blame them if they come across a scene like the one described above?) will do chest compressions and the patient stands a greater chance of survival. The compressions are recommended when an adult patient is not breathing "normally". They describe "normal" as between 10 and 40 breaths a minute. Any slower than 10 is agonal breathing and any faster than 40 the body is not taking in sufficient oxygen. The compressions should be done even if there is a pulse. Apparently, someone would have to do chest compressions for over 24 hours before the rhythm of the heart would be disturbed. Sounds a lot easier to work out whether to do CPR or not - any comments from you professionals?
