Or if intubated with a regular ETT. Like Tom said, it's rare that it would be used, we know how much some EMT's hate intubation:) On a different note, the ECG readout on these things is pretty dire. We have one that gets used quite regularly in house. Working in non-cardic Paed's, we dont have to worry too much about the ECG, but the morphology is so hard to make out it's rediculous. It seems to flatten alot of the QRS out and the T is really hard to see...in my opinion. Has'nt anyone mentioned that a portable ABG analyser might be more useful (I have links if anyone wants them)? Getting you lad's doing this might help out department staff too. "Compensated respiratory acidosis" might sound better than "some old dear who's turned a bit blue, might have COPD"! cheers
