Hi, Paulette -- the msg was sent before Larry's decline, so it was a moot point by then. Re the 4/20 breaths, I would try dropping the backup " (target") rate as low as it will go (i. e. 0 if it will do that in iVAPS mode, or if not, try the S mode) , esp. when he is awake, and see if that helps. My guess is the big breaths are backup rate breaths and those will be at different settings. For the bed, sure you as an RN know this, but you want a bed that tilts as well as changes foot/head/overall height.
Might be easier to do this via e-mail -- is there a better addy to use?
