Now, I will admit that new technology ideas have always caught my attention pretty easily to at least look into, and there are certainly plenty of things that only really add complication to things. At times, though, there is some value in the right situation. You can't just take any higher level of complication as always bad. I would agree that with the autopulse, it adds expense every time you use it on top of the high initial cost and doesn't really add any options you don't have without it.
The thing I thought might have some value is that it might open a new option sometimes. Not having experience with it I wanted to see if anyone else agreed that it might have some worth. A $15,000 fiber optic scope really is just another barely used thing to train on for that one time you use it and try not to break. If nothing else, though, the ETView at $120 to sit around and only needing to plug it into the barely used laptop when you need it on a difficult airway seems it could be of enough benefit. As far as the other methods to check placement yeah, but would it be bad to be sure without needing to check on that difficult placement when every bit of time you take to check and possibly redo the intubation matters? Can you always see the tube pass the vocal cords when the patient is on a backboard or pinned somewhere? If you are confirming placement by results of a proper breath, you leave the chance of having to replace the tube if you don't get that positive response and may waste time that may make a difference. Also it would allow you be certain you avoid bronchial intubation, or easily check for it if the patient is jostled.
For AZCEP, the thing about this tube compared to those fiber optic ones is the tube itself is $120, but it just plugs into any computer to view by a USB plug and at least with the service I ride with, laptops are always carried already to file reports on. There isn't that expensive extra equipment as the micro-camera is built into the tube itself.
I'm not saying that maybe it isn't ever worth the cost. I haven't actually done it and don't know what complications there might really be. Responses simply dismissing it as another gadget though don't say anything of use.
