An Ambulance Officer is many things however broadly speaking it is 98% people management, 1.9% fundamental praxis and 0.1% advanced care.
Most of the jobs you will go to are acute exacerbations of chronic disease (angina, heart disease, asthma/COPD, diabetes, renal failure etc) and are not glamorous or exciting. Despite what your poorly written textbook tells you, most patients are not in an immediate threat to life. There is nothing exciting about attempting to resuscitate somebody in cardiac arrest on the floor of their home with the family watching you when you know full well there are overwhelming odds he is going to stay dead. There is nothing exciting about having to tell that persons family their loved one is dead and Brown finds it an incredibly undignified way to die.
Many Americans it seems are "trauma junkies" well trauma is a horrible disease which has a profoundly devastating effect on society. There is nothing "cool" about assessing and treating somebody who amputated his arm with a rotary saw and may never be able to use it properly meaning he can't work and support his family any longer or going to a road traffic accident where the occupants have died meaning their families are going to forever be burdened with grief, anger and the untold emotional pressure of loosing a loved one.
Do you have an interest in talking with people and building meaningful rapport with them in order to provide care? Do you have an interest in biology, chemistry and the inner workings of the body as they relate to physiologic and pathophysiologic states? Do you have an interest in continuing education? Do you think you are able to relate well to people in different circumstances and situations? Do you work well with others?
