as a surgical specialist i am very not qualified to treat heart attacks (which other than chewing an aspirin and breathing oxygen requires a massive cath lab and an interventional cardiologist or a cardiac surgeon with a special OR including a cardiopulmonary bypass pump and a perfusionist; my current decent size hospital on the ground has neither of these) and barely more useful than a medical student at 99% of various medical problems a normal person may have. without a knife, anesthesia, and millions of dollars of equipment i’d just be asking chat gpt how to do breathing exercises with an elderly person having a panic attack
