Nursing Assistants and Oxygen therapy

I guess I'm a little frustrated and I'd like to maybe start a discussion and or just get some opinions from colleagues especially trained colleagues.

Now iv actually had medical gases training on courses outside the nhs (Though they're now very out of date), iv been a Nursing Assistant for 5 years, to me it's an area to gain experience before training to become a Registered General Nurse.

Iv spent alot of time also asking questions, listening and learning, reading up as much as I can mainly to make it easier when I start my training.

Now Nursing Assistants aren't trained or insured to give oxygen, fair enough its a medication but big but, we still end up giving it either due to working in an acute setting (I work in acute respiratory for example) or because its simply faster for us to put a patient on oxygen or switch it off then call a busy Nurse (Nurses typically don't seem to care either, if anything they like the fact we know what we're doing).

Like iv had many situations where iv got patients frequently desaturating while on optiflo at full pelt, and they have a tank next to them....do I call a busy Nurse every time they need a 100% non-rebreath when I have two arms and a brain?

It especially doesn't make any sense considering we escort patients on oxygen.

It's also extra interesting they've been extra with this when we're fighting for Band 3 and 5 years back pay.....gotta act like we're all stupid Assistants that can't handle abit of training on something we deal with every single bloody day and well pay us a wage that meets those responsibilities.

Sorry turned into a vent.

Really naff day aswell so
