Decubitus ulcer prevention: a new investigative method using transcutaneous oxygen tension measurement

Sacral skin oxygen tension, measured by a noninvasive technique in ten healthy subjects, remained in the normal range when they were lying on a "super-soft" mattress or in the 30 degrees lateral position. Therefore, these methods are effective in decubitus ulcer prevention. Skin oxygen tension measurement allows immediate assessment of the efficacy of measures to prevent decubitus ulcers.
