OASIS Nurse

Okay after 33 yrs back is giving out. hx ICU,ER,Med/Surg, and Correctional healthcare, which I am hoping to return to. But in the event that this falls through? What is all the hoop ha about being a certified OASIS nurse about. Can you make a living and not be involved in direct pt care as in lifting and tugging?. As far as the mental and emotional challenge,and descipline of study and test. I fear not! just what to make sure that this can get me over the next 5 yrs towards the big Retirement days. thanks
