Hmm, those numbers seem optimistic as well. I’ve had doctors and veterinarians tell me that survival rates with a good outcome are closer to 4%. Often they’ll be resuscitated, but succumb to their ailments shortly after. Other times they’re revived and stay alive, but suffer severe brain damage. If they survive and don’t have brain damage, they still have bruised organs and broken ribs from the procedure itself and will need further treatment. Basically everything I’ve heard about CPR from medical practitioners make it sound like an absolute last-ditch effort that rarely works.
