The problem is that Hisao is your narrator, and since he is able to narrate all the stuff about Misha giving him CPR that means that he is conscious at the time. Sure, Misha could have mistaken him for being unconscious, but he seems to at least have his eyes open and be following events around him.
(He also stays concious during CPR until Shizune comes back with the nurse which actually had me laughing out loud when I read it the first time. I'm not sure giving the kiss of life to a conscious person would even work. They'd probably breathe against your breathing just by reflex.)
Again: It doesn't matter what Hisao's condition is - as long as he is conscious, he is breathing, and his heart is beating, thus there is no reason to perform CPR.
CPR is quite likely to stop whatever spontaneous pulse and breathing the patient still has going, replacing it with the artificial version - and breaking a few ribs in the process*
If Hisao had blacked out before Misha started CPR and been told about it after he woke up again, everything would have been fine.
*In first aid courses, currently the procedure we teach is to start CPR after ascertaining the patient is unconscious and not breathing. Checking for pulse is no longer recommended for lay helpers, because it can be difficult to correctly find a pulse if it is weak and you're not doing it regularly and also because if there is no respiration there's a high likelihood** of there not being any pulse either.
I'd still take the few seconds to ascertain the patient really has no pulse left before starting a measure that might mess up whatever pulse there might still be.
**not sure how high right now...
2: We've got pretty much the epitome of unreliable narrator here. He's having a near-death out-of-body experience here. It's a bit of a cop-out, admitted, but we have no guarantee that what he's seeing is what's happening. Additionally, given our limited understanding of the very concept of consciousness, as well as anecdotal accounts of individuals "perceiving" while ostensibly unconscious, it's entirely an assumption that what he purports to be seeing is the product of a conscious mind. To put it more bluntly, if I had mentioned Hisao seeing Rin sprout elephant ears, I wouldn't put much stock into someone's objection of the biological improbability of that event.
3: Current guidelines recommend compression-only CPR for SCA. No "romantic" kiss of life (followed by equally romantic vomiting all over the place).
4: Keep in mind the distinction between what you should do (i.e., CPR recommendations), what is best to do (i.e., omniscient/hindsight), and what an actual human being might do in the heat of the moment (i.e., probably neither of the above).
5: Hisao isn't the standard "stranger collapsing in the middle of the street." He's a high-risk candidate for SCA with a diagnosed heart condition. His circumstances weigh pretty heavily in favor of "when in doubt, CPR."
6: Blacking out may have been the standard major heart trauma approach in the VN (cf: intro, Lilly's good end), but it was dramatically appropriate for the "I'm such a pathetic loser" vibe being conveyed. Missing out on the action so totally just wouldn't have been dramatically appropriate here.
