bottoming out

Introduction

Expression used to describe inadequate support from a mattress overlay or seat cushion as determined by a 'hand check.' To perform a hand check, the caregiver places an outstretched hand (palm up) under the overlay or cushion below the pressure ulcer or that part of the body at risk for a pressure ulcer. If the caregiver feels less than an inch of support material, the patient has bottomed out & the support surface is therefore inadequate.
