In our unit we use individual therometers for each of our infants. At present we are having trouble keeping a supply due to back orders. What kind of therometers does everyone else use? Are you having problems obtaining them? What manufacture do you use? Does anyone use the IVAC digital and go from bed to bed with it ? If you use the IVAC do you have any problems with infection control? How do you clean the main unit between infants? Thanks, JBKRUM
