The years of experience will always help you be a more competent/safe nurse. The salary is the same in cath lab as in any critical care setting in the hospital. As for outpatient it may be slightly lower, unless you take call. I work part time, 15years of experience, about 100 hrs of call every 2 weeks, and make 70,000+/yr. in Southern California. My average productive hours a pay period, 30 hrs.
