I was wondering what are the duties and typical day of nurses who work in the cardiac cath lab. I've taken post-cath patients and understand the procedure itself, but what do nurses do who work in the cath lab? Do they work mostly day shifts? 8 or 12 hours? Do they take call for weekends/nights in case of emergencies? Are families allowed in the cath lab during the procedures?What skills are most important in this area?
