I assume you are working on a P/B waiver (Paramedic/Basic considered ALS, as opposed to P/P). You should have been trained on this stuff the first day you worked on an ALS truck.
I suggest you take a paramedic assist or ALS assist course. Below is a link to an outline for one of the classes:
http://wmems.org/PAstOut.pdf
The skills taught include:
Spiking an IV bag
Attaching a monitor
securing an IV
securing an ET tube
Possibly using Sp02 (if its not a basic tool)
Possibly taking FSBG (if its not a basic tool)
Hopefully, training on the monitor your service uses-- how to check it, clean it, attach therapy pads, print strips, etc.
These should all be skills taught in basic school, but are often not. They should also have been taught by the medic you work with earlier rather then later-- before he needs you to use these skills.
If you want to learn about the supplies and equipment you carry-- ask the medic. Go through the ambulance top to bottom (dont you at the beginning of your shift anyway?) Even if you cant on calls, learn how to use everything, learn when specific things are used, learn why...?
Good Luck! (Knowledge is Power!)
