Advances in Non-Invasive Blood Pressure Measurement Techniques

Tuukka Panula et al.

Summary: Hypertension is a marker for cardiovascular diseases and can be life threatening. Non-invasive blood pressure monitoring techniques have been proposed and investigated. Telemonitoring solutions for home management of hypertension have accelerated the development of new monitoring techniques. This review highlights clinical validation, trade-offs, current measurement techniques, promising studies, modeling and machine learning approaches, and unresolved challenges.

The pre-ejection period is a highly stress dependent parameter of paramount importance for pulse-wave-velocity based applications

Niklas Pilz et al.

Summary: The purpose of this study is to characterize the pre-ejection period (PEP) under mental and physical stress and explore its relations to other cardiovascular parameters such as heart rate, as well as its importance for blood pressure (BP) estimation. The results showed that PEP is highly dependent on mental and physical load. It is strongly correlated with indicators of sympathetic strain. PEP has large interindividual variability at rest and different dynamics under load, which is crucial for pulse-wave-velocity (PWV) based BP estimation.

Modulation of Pulse Propagation and Blood Flow via Cuff Inflation-New Distal Insights

Laura I. Bogatu et al.

Summary: The study explores the underutilized arrangements of sensors involving cuff devices in critical care to reveal additional information on compensatory mechanisms. Invasive BP experimental data collected in two patients monitored in the OR shows highly dynamic processes occurring in the distal arm during cuff inflation, with significant effects on mean arterial pressure and pulse transit time. A model is developed to explain and reproduce the observed behaviors, aiming to further develop measurement strategies for acquiring information on various vascular parameters.
