Seriously, how often are most RNs intubating patients? CRNAs and prehospital nurses? Sure. However, how often is the average med/surge, scrub nurse, SNF nurse, or heck, even emergency nurses intubating? Similarly, how often are these same nurses doing crics, decompressions, or central lines? By "doing" I mean actually performing the procedure. Not assisting. Not observing. As in the physician isn't even in the room and the RN goes, "Let's intubate!" The vast amount of RNs (which, for the record, challenging isn't limited to just "Code team or rapid response team nurses," but in many cases RNs as a whole) are not intubating, nor performing any of those other procedures, on even an irregular basis. You say this may be an individual nurse's strongest area, but then intubation similarly may be an individual paramedic's strongest area.
Similarly, assisting in a procedure is not the same as performing a procedure. A scrub tech doesn't get to be the primary surgeon after assisting with hundreds of operations. An EMT-B doesn't get to manually defibrillate on his own despite assisting with manual defibrillations potentially hundreds of times. That's because doing, assisting, and observing are three different things. Sure, you can learn a lot by assisting and observing, but the mere act of doing either or both does not mean that an individual is competent to perform an intervention on their own.
JP, you still have a lot to learn about nurses and hospital situations as well as all the other medical professions. You should not judge everyone by just the one nursing home nurse you know. Are you really so naive at this point that you believe a critical care RN and those that have chosen to work in a SNF are the same? Both can be quality professionals with their own areas of expertise and skill sets but I doubt the SNF RN wants to do RSI and intubate. They at least realize their limitiations.
You have not worked in critical care units or on specialty teams. You have not worked in Pedi ICUs or L&D. You have never been on a hospital code or rapid response team. You have never been on a Flight team. You can not speak for what ALL RNs can or can not do. Nursing is a vast field. EMS is very, very limited. You also seem to think all EMTs and Paramedics are the same because they had the same training. But, even if they are that training is very limited to just one small area of medicine. The majority of patients in a hospital are also not necessarily transported by ambulance but some EMT(P)s believe that is the only way to get there. You make a lot of generalizations without realizing how large the field of medicine actually is and the opportunities in it.
In some of the hospitals I have been in, the Rapid Response and Code teams can definitely function without a doctor present. If it is determined the patient needs intubating the RN gives the medication and I, the RRT, intubates. If it is a Flight or Specialty RN, they can do the intubation. If it is in L&D, the RN can intubate. If a baby has a pneumo when they are on some serious ventilation in the ICU, the closest person who is trained to do a needle decompression can perform it in an emergency. That could be the RRT or the RN who has had this training.
If a Paramedic is only doing one or two intubations per year while the Flight, Specialty or CCT RN is required to do at least 10 per year, who do you think might be a little better. The fact that RNs know they must have certain experience and continue to practice to stay current sets them apart.
Even having seen advanced procedures being done is better than never having seen them performed except on a manikin.
Also, I personally don't like that fact that some some EMT(P)s who have no interest in patient care are actually placed into a situation to where they might have to touch patients either.
JP, with the education you have now, you should be starting to think beyond the "EMT-B" level to at least start to process advanced concepts in medicine better and to recognize some of the other specialty areas in medicine.
Also for the sake of this topic, there are a few states here in the U.S. that allows RNs to function in prehospital EMS within their own scope as RNs and perform whatever skills their medical director determines. They may not need another "cert" such as PHRN or MICN.
