I had a personal stethoscope that I liked having on the gurney. It was always there if I decided to auscultate breath sounds in the home versus in the ambulance. I really liked it on the gurney when nobody was on the gurney so I could easily see it. Ironically, I kept losing it in mysterious ways. The last time I had a stethoscope, my partner put it on the back of it when the patient sat on the gurney. Pulling the patient out of the ambulance, I felt drag like something was stuck, but we didn't see anything, and pulled hard. The stethoscope had caught onto the rail in the back and the tubing ripped. I've been using the rig/bag stethoscope ever since. We have on stethoscope in our med bag that we carry on scene (we only carry our stuff on scene if fire isn't first, I like to have it if we are going to walk far eg going through the airport) and then there is one hanging on the catch net the ambulance. It's okay to lose those ones... They are very cheap, but I feel like I hear the same with it compared to my Littman. I used to try to do heart tones, but I have gotten lazy.
