Maybe it's just different attitudes showing from across the world but the technology exists to make our job safer so why not embrace it. Yes everybody who works on an ambulance should be able to lift but equally everybody who works on an ambulance should be looking to do the minimum amount of lifting.
Can your patient walk or is there a clinical reason why they should not?
We should be embracing things that make what we do safer such as PAT slides, transfer boards, glide sheets etc.
As a Uk volunteer most of our ambulances now have a back that will lower and a ramp that comes down agin to avoid lifting.
As for the comments "oh well how about we just keep it for the fat people" , Rember the vast majority of moving and handerling injuries are caused by cumulative bad practice not a one off incident.
The vast majority of NHS ambulances come with tail lifts.
