Don't know about them specifically, but most HEMS programs tests are fairly standard material for the industry. I would have a rock solid grasp on standard ACLS & PALS stuff, good understand of standard ventilator modes, settings, and strategies. ABG interpretation. RSI knowledge to include indications & considerations, drugs, doses, procedure to include failed airway. Basic knowledge and dosing for things like Levophed, Vasopressin, Epi, Cardene, Esmolol, Labetalol, Propofol. Management of traumatic heads, ICH, AAA, Dissections, trauma scenarios, and maybe some high risk OB stuff. Our CC test doesn't include anything like Swans, IABP, or ECMO stuff, really just testing a baseline CC knowledge. Good luck.
