Journal ArticleDOI
Toward Ubiquitous Blood Pressure Monitoring via Pulse Transit Time: Theory and Practice.
Ramakrishna Mukkamala,Jin-Oh Hahn,Omer T. Inan,Lalit Keshav Mestha,Chang-Sei Kim,Hakan Toreyin,Survi Kyal +6 more
TL;DR: 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.
Journal ArticleDOI
GPS-based real-time identification of tire-road friction coefficient
TL;DR: A new tire-road friction coefficient estimation algorithm based on measurements related to the lateral dynamics of the vehicle that does not require large longitudinal slip to provide reliable friction estimates and can work very effectively in identifying a slippery road.
Journal ArticleDOI
Smartphone-based blood pressure monitoring via the oscillometric finger-pressing method
Anand Chandrasekhar,Chang-Sei Kim,Chang-Sei Kim,Mohammed Bakir Naji,Keerthana Natarajan,Jin-Oh Hahn,Ramakrishna Mukkamala +6 more
TL;DR: A smartphone-based device for cuff-less and calibration-free monitoring of systolic and diastolic blood pressure is comparable to cuff-based devices and extended the oscillometric principle, which is used by most automatic cuff devices, to develop a cuff-without BP monitoring device using a smartphone.
Journal ArticleDOI
Ballistocardiogram as Proximal Timing Reference for Pulse Transit Time Measurement: Potential for Cuffless Blood Pressure Monitoring
TL;DR: It is concluded that BCG is an adequate proximal timing reference in deriving PTT, and that BCg-based PTT may be superior to ECG-based PAT in estimating DP.
Journal ArticleDOI
Weighing Scale-Based Pulse Transit Time is a Superior Marker of Blood Pressure than Conventional Pulse Arrival Time.
Stephanie L.-O. Martin,Andrew M. Carek,Chang-Sei Kim,Hazar Ashouri,Omer T. Inan,Jin-Oh Hahn,Ramakrishna Mukkamala +6 more
TL;DR: This work measured “scale PTT”, conventional PAT, and cuff BP in humans during interventions that increased BP but changed PEP and smooth muscle contraction differently, and assessed a bathroom weighing scale-like system for convenient measurement of ballistocardiography and foot PPG waveforms in terms of its ability to improve tracking of BP in individual subjects.
