Invasive v. non-invasive measurement of arterial pressure. Comparison of two automatic methods and simultaneously measured direct intra-arterial pressure.
Two indirect arterial pressure monitors, the Finapres and the Accutorr, were investigated and compared with the direct measurement of intra-arterial pressure. Pressures in patients in a variety of circulatory states were measured and analysed in relation to two types of random error: first, the "intra-individual standard error" (within one session of measurement) and second, the "inter-individu...

BACKGROUND Despite increased interest in non-invasive arterial pressure monitoring, the majority of commercially available technologies have failed to satisfy the limits established for the validation of automatic arterial pressure monitoring by the Association for the Advancement of Medical Instrumentation (AAMI). According to the ANSI/AAMI/ISO 81060-2:2013 standards, the group-average accurac...
متن کاملContinuous blood pressure measurement using the pulse transit time: Comparison to intra-arterial measurement.
Continuous blood pressure (BP) measurement allows the investigation of transient changes in BP and thus may give insights into mechanisms of BP control. We validated a continuous, non-invasive BP measurement based on the pulse transit time (PTT), i.e., BP(PTT), by comparing it with the intra-arterial BP (BP(i.a.)) measurement. Twelve subjects (five females and seven males) were included. BP(i.a...
متن کاملPulse pressure variation, stroke volume variation and dynamic arterial elastance
Which means that SVV (%) ≈ pulse pressure variation (PPV; %) for FloTracTM. With the present mathematical equation, it can be demonstrated that the SVV calculated by FloTracTM (SVVFT) is not infl uenced by Khi, which means that SVVFT calculation does not include eff ective arterial elastance (Ea). Th e originality of Garcia and colleagues’ fi nding is that they realized that when measuring PPV ...
متن کاملBP Measurement Circadian Variation of Arterial Pressure Wave Reflections
Background: Various factors are implicated in the circadian pattern of cardiovascular vulnerability. The exact mechanisms involved in the peak incidence of cardiovascular events occurring during the early morning hours after awaking are not completely known. The purpose of our study was to investigate the circadian variation of timing and intensity of wave reflections in healthy individuals and...
