Self-reported sensitivity to continuous noninvasive blood pressure monitoring via the radial artery.
Many blood pressure (BP) methods common in psychosomatic research have salient limitations, including subject discomfort, sampling limits, and measurement validity concerns. This study examines the utility of the Vasotrac APM 205 BP monitor, which works via continuous nonocclusive compression and decompression of the radial artery, primarily in regard to its intrusiveness. ⋯ Responses indicate the Vasotrac is nonintrusive during extended wear. Its sampling rate far exceeds that of ausculatory and oscillometric methods, and so it may offer further reliability and validity benefits for BP measurement.
