Disadvantages: Have to carry heavy patients, back injuries, being kicked at, spit at and urinated on, sitting on a street corner (not all systems have their units posting on a street corner. Some have a base or fire station to sit at and this can be a possitve thing. for 12 hours in a small seat, see horrific things, high burn out, deal with the scum of the earth on a daily basis, and risk your life daily for lousy pay.
Advantages: The 1 out of 20 patients that actually needs an ambulance and the feeling you get when you are able to help them. Even though most patients do not truly need and ambulance, paramedics do make a difference in those people's lives just by being there for them on what they feel is their worst day. Being able to make a difference is rewarding to the provider and is often times what motivates them to become a paramedic.
