Hi Mike thanks so much for responding. I do not have any evidence base practice resources to cite. However, if our patient is only on 1 to 2 drips, we lay the pumps on the patient. Because of this and our very sensitive pumps, any air in the chamber will get in the tubing. More than 2 drips we will hang them from the ceiling. Even them though because of movement in the helicopter air can get in the tubing. I think from a safety standpoint, it’s easier to miss changes in a patient’s VS or status when you are constantly trying to fix beeping pumps, you know what I mean? Thanks again.
