Abstract
The invention relates to a form of a passive or active annunciator that solves the problem of reminding a caregiver to reposition a patient at risk for aspiration usually located in an adjustable bed to some predetermined angular position. The annunciator may take the form of an inclinometer (100) that measures the angle of the bed (160) relative to a local gravity reference or a goniometer that measures the angle between the horizontal (140) and elevated portions (130) of the bed. The invention reminds the caregiver of the patient at risk for aspiration to maintain or reestablish the elevation of the torso of the patient at risk for aspiration to at least 30 degrees up to 45 degrees above the local horizontal to prevent or reduce the incidence of aspiration.
