Abstract
According to a preferred embodiment, there is provided an electronic patient monitor for use in reducing the risk of decubitus ulcers. The monitor utilizes a separate sensor which senses the position of the patient in the bed or chair for purposes of determining when the patient moves. Additionally, the monitor broadcasts masking noise through its own, or through a remote, speaker, thereby enabling the patient to rest more comfortably in a noisy institutional environment. If the patient does not move on his or her own accord within a predetermined turn interval, the masking sound broadcast will be terminated which will gently encourage the patient to move. An alarm may additionally be sounded to notify the caregiver that the patient needs to be manually turned to reduce the risk of decubitus ulcers.
