I am a lifeguard and have seen the new CPR standards. It has changed from 15 compressions per 2 breaths for adults to 30 compressions per 2 breaths for all ages. This baffles me because of the ratio. My concern is this: when you're trying to pump blood through chest compressions, there has to be blood to pump. In order to have blood to pump, oxygen must be provided. Is 30 compressions not more than necessary? Will the compressions be pumping an empty heart? I see a problem especially for children if these standards apply. Before, less compressions to breath ratio applied. Also, will having less breaths damage the brain even more seeing that it isn't being provided oxygen as it should? These standards confuse me on how they are more effective, but that might be because of my medical expertise. If I know that they are more effective that will put me to rest on the job. Thanks.
Now we know why they say it's good to have "2 man CPR." What is the ratio for two people? Has that changed? Compressions are good if they are firm and deep enough, but your right... without oxygen...what good are you doing. Poeple who have to be compressed and only have oxygen by mouth to mouth usually don't make it if they don't recover right away. By the time they get to a hospital, brain damge due to hypoxia, or lack of oxygen, has already been done. 30 to 2 sounds scary. Always enlist a bystander for help to give more breaths quicker and faster with compressions to better your chances.
