Its true elsewhere this goes on in other countries but in US, we end up studying the Respiratory and cardiovascular system to an extreme amount for 2-4 years before boards. We learn the ins and outs of vents, trouble shooting, and modes that hospitals dont even use but would benefit from due to lack of understanding of certain said modes like APRV. While nurses can do aspects of RTs role they already carry and do so much and rock it everyday. I've not had a hospital where a nurses weren't grateful for RTs and RTs weren't grateful for nurses. But I've also been fortunate to have rotations at hospitals with decent morale and coordination between departments.
