Key result
Investigations using cuff-pressure induced PAT changes were conducted to provide insights into BP-PAT sensitivities for subjects at rest, with no quantitative results reported in the abstract.
Why the study?
Can cuff-pressure induced PAT changes provide insights into BP-PAT sensitivities for calibrating blood pressure surrogates in subjects at rest?
Can cuff-pressure induced PAT changes provide insights into BP-PAT sensitivities for calibrating blood pressure surrogates in subjects at rest?
The study investigates cuff-pressure induced PAT changes to address the calibration problem of non-invasive blood pressure surrogates like PAT and PTT.
Cuff-pressure PAT sensitivity findings remain hypothesis-generating for BP surrogate calibration; should not yet change non-invasive monitoring practice.
Arterial Blood Pressure (ABP) is one of the most often measured vital parameters in daily clinical practice. State-of-the-Art non-invasive ABP measurement technologies have obvious limitations and are still mainly based on uncomfortable techniques by complete or partial occlusions of arteries. Additionally, embodiments are bulky, difficult to apply for the layman, or provide only intermittent measurements. We have been investigating the pulse arrival time (PAT) and pulse transit time (PTT) methodology for unobtrusive blood pressure (BP) measurements. However, BP surrogates like PAT or PTT require a calibration step, which is currently an unresolved problem. In this paper we report on our investigations using cuff-pressure induced PAT changes in order to provide insights in the BP-PAT sensitivities for subjects at rest.
