was michael's reflection of experiences as a medical student. >> you need a large in case they're bleeding. do you know how to start an i.v.? >> actually, no. >> "e.r." is a hospital show, but it's really an action movie. >> three walking wounded. red urgent, yellow critical and black a gurney. >> got it. >> a gurney comes in, people are shouting instructions, climbing on the body and doing cpr and racing off to the surgical suite. >> get that gurney out of there! >> someone wanders in. they're tossing around medical jargon. they don't stop to explain what it is. prep for a peritoneal lavage. i think i know what that is now, but only because i watched a lot of "e.r." over the years. >> you could try but i don't think his heart would take it. >> you try. >> we can bypass him. >> that would be the fastest way. what do you think? >> you're the attending. >> there was so much information coming at you that i think it made the experience feel as if you had to watch it in the same way that you'd watch a film. you had to stay involved in it
