How do I view the last patient weight on a Hill-Rom Stretcher?
 

On stretchers with an integrated scale, to view the last patient weight, press the Last Weight control. The display will show the last weight taken or 0.0 (if the stretcher was adjusted to zero after the patient weight was taken). This Last Weight feature is a Hill-Rom exclusive feature.
