Wearable sensors to continuously measure blood pressure (BP) and derived cardiovascular variables have the potential to revolutionize patient monitoring. Current wearable methods analyzing time components (e.g., pulse transit time) still lack clinical accuracy, whereas existing technologies for direct BP measurement are too bulky. Here we present a new art of continuous non-invasive arterial blood pressure monitoring (CNAP2GO). It directly measures BP by using a new "volume control technique… Expand

Continuous cuff-less blood pressure monitoring based on the pulse arrival time approach: The impact of posture
The results show the failure of blood pressure inference based on simple calibration strategies using the PAT measure only, and emphasize the importance of accessing context information in personal healthcare applications, where vital sign monitoring is typically unsupervised. Expand
CNAP – Evolution of Continuous Non-Invasive Arterial Blood Pressure Monitoring
CNAP concentrates on the clinically important BPinformation such as absolute BP and BP-changes as well as physiological BP-rhythms andBP-waveforms, where other hemodynamic parameters like cardiac output (CO) and dynamic fluid management parameters (e.g. pulse pressure variation PPV) can be derived.

Blood Pressure Estimation Using Photoplethysmography Only: Comparison between Different Machine Learning Approaches
This study developed and compared three machine learning algorithms to estimate BPs using PPG only and revealed that the regression tree algorithm was the best approach with overall acceptable accuracy to ISO standard for BP device validation. Expand
Toward Ubiquitous Blood Pressure Monitoring via Pulse Transit Time: Theory and Practice
This review explains the conventional BP measurement methods and their limitations; presents models to summarize the theory of the PTT-BP relationship; outlines the approach while pinpointing the key challenges; and discusses realistic expectations for the approach. Expand
Impact of heart disease and calibration interval on accuracy of pulse transit time-based blood pressure estimation.
The findings demonstrate that both heart disease and the calibration interval can influence the accuracy of PTT-based BP estimation and should be taken into consideration to improve estimation accuracy. Expand
Is pulse transit time a good indicator of blood pressure changes during short physical exercise in a young population?
There might be a need for an improved measurement accuracy of the sensors and data processing techniques in use for the applicability of the Moens-Korteweg equation for young people having flexible arteries. Expand
Continuous non-invasive blood pressure monitoring using concentrically interlocking control loops
The instrument, in contrast to intermittent set point readjustments of the conventional vascular unloading technique, delivers BP without interruptions, thus refining the Penáz' principle. Expand
Comparison of noninvasive pulse transit time estimates as markers of blood pressure using invasive pulse transit time measurements as a reference
PPG‐PTT was not different from I‐ PTT and superior to the popular PAT as a marker of BP, and the pre‐ejection period component of PAT was responsible for its inferior correlation with BP. Expand
Conformable amplified lead zirconate titanate sensors with enhanced piezoelectric response for cutaneous pressure monitoring.
Experimental and theoretical studies reveal enhanced piezoelectric responses in lead zirconate titanate that follow from integration on soft supports as well as engineering behaviours of the associated devices, which demonstrate capabilities for measuring radial artery augmentation index and pulse pressure velocity.

Pulse Decomposition Analysis of the digital arterial pulse during hemorrhage simulation
A new approach to tracking blood pressure, and pulse pressure specifically, is presented that is based on a new form of pulse pressure wave analysis called Pulse Decomposition Analysis (PDA), with a hypothesis that the PDA parameter T13, the timing delay between the first and third component pulses, correlates with pulse pressure.
