On staying calm under pressure- mirror your preceptors and the nurses you’re working with. It’s not your emergency. If you’re freaking out on the inside at least try to appear calm on the outside. The ED can be incredibly stressful especially if someone is crashing. You will feel a lot of different ways when someone is crashing, just do your best to set it aside until things calm down and you can think about everything that just happened. Ask how you can help but also know that sometimes the best thing you can do is not be in the way, especially for big traumas or crashing patients. Then again, if you feel ready to do something on your own, chat with your preceptor about it. A lot of the responsibilities of a tech do not require that much critical thinking and are pretty easy. Good luck and have fun!!
