Your stats are looking good. Your gre is fine. I got in with less than 1000. Im sure you will get an invitation to interview. It's all about how you present yourself. Lot of applicants have really great stats but they screw their interview part.just know your Stuff in your IcU area in details. Taking grad sciences courses would make your application stronger. this would show to the admission committee that you could do grad studies.goodluck. Don't stress it out .you have a pretty stats.
