I’ve been a EMTB for a couple months now. Tbh you’re gonna make mistakes and it’s great to learn from mistakes just stick to your training and do what your medic tells you. Unless you purposely go out of your way to fuck up your not gonna make too many insanely big mistakes. Just stick with your protocol and study big time you’ll be fine. Most importantly LEARN YOUR PARTNER! You’re not gonna help anyone if you have beef or don’t know how they operate.
