With the new medical cardiac arrest directive I have multiple questions: 1. If a patient re-arrests after getting a ROSC do we a) start the 20mins over? B) analyze once and then carry on to hospital with no further analyzes, or c) complete the remainder of the initial 20mins of CPR? Also does this answer change if the ROSC is at the initial site or in the back of the ambulance? 2. If patient arrests for the 1st time in the back of the ambulance, do you stop for the whole 20mins of CPR, does location of arrest to hospital make a difference? 3. If you have a refractory v-fib and we start early transport to hospital, do we continue to pull over and shock every 2 mins or so we stop shocking while on route to hospital?
