I would disagree for a few reasons, at least for its application to cardiac arrest. It might have some niche applications, but that's only speculative.
The main determinant of successful CPR is maintaining coronary perfusion pressure with unrelenting chest compressions so that the heart has a fighting chance at starting to beat normally again. Moving the blood so that it has enough pressure at the aorta where the coronaries branch off of is way way way more important than keeping it oxygenated, which we're already pretty good at. In fact, over-oxygenation in CPR has been shown to be detrimental to outcomes because it causes oxidative stress at the cellular level. Oxygen is nasty, it's amazing that life evolved to harness it.
I do agree that modern medicine (especially emergency medicine) is really cool, that's why I switched careers after working in software engineering. We have lots of tools at our disposal, it's already science fiction. Modern resuscitation involves drugs that manipulate the ion channels of the heart in various ways, we can shift fluids around by changing the osmolarity of IV fluids (and we can pump them into you through your bones after drilling into them if needed...), cardiac monitors and AEDs will time a shock just right depending on the dysrhythmia to increase the odds of success, we can even just repeatedly shock a heart to make it beat in some situations like an AV block. And that's just the stuff that they let paramedics do (i.e. trained monkeys, I am one).
