Hello! I started working with a town close to me as an attendant (someone who is certified in CPR but is in an EMT-B class). All the calls we get are 911 calls. I was taught about a month ago how to take blood pressure and pulse by my crew chief. I can do both fine when I am on scene, but as soon I get in the ambulance I cannot hear/feel anything. Does anyone have any suggestions on how to get past the noise and all the bumping around so that I can take the BP and pulse en route?
