Ok, quick explanation to the previously used abreviations.......
PM, well, I hope you all know this one but it is different to the below. Preventative Maintenance; change batteries in pumps/kits in vents, anaesthetics machines, that kind of thing.
SPT, safety and performance testing, ie, electrical safety test with performance evaluation (flows, occlusions, nibp cal, you know the kind of thing).
So, before you ask, you can do an SPT without a PM but NEVER a PM without a SPT.
