title: Noninvasive blood pressure patterns.
abstract: The apparatus described in this report provides a noninvasive, nonocclusive technique for continuously measuring cutaneous blood pressure changes over extended periods of time. The data are acquired with miniature pressure transducers mechanically coupled to the cutaneous tissue overlying the thumb and wrist. The cutaneous blood pressure patterns obtained with this apparatus indicate that the stress of uterine contractions causes readily identifiable blood pressure pattern changes. Preliminary results suggest that data obtained with this instrumentation is more complete than that obtainable with intermittent occlusive blood pressure measuring systems currently in use.
