Anyone can buy a pulse ox off the shelf and use it, should we let EMT-Bs use pulseox's since it's so easy to use [clip on finger, read number]? How about spirometers? Those are available to the general public, should BLS units be equipped with them? Should BLS be giving insulin to hyperglycemics? Afterall, there's a ton of people who give themselves insulin everyday and they aren't medical providers.
AEDs aren't allowed on ambulances in places? I know that some places require a special license for the company [cooperate, not the provider], but the possibility of doing something stupid with an AED, like postponing transport to get a number [you know that'll happen, right. Little EMT-Suzy with her 110 hour bare bones class is going to stop for 5 minutes to get a reading and delay transport/calling ALS], is less likely.
As far as ECGs, do you think EMT-Bs should have access to those? There's a thread someplace asking to be revived if you do.
