Title: Recent Cuff-less Non-invasive Blood Pressure Monitoring Devices
Time: Monday, January 2, 2012, 14.00-15.00
Location: Room #201, Department of Electrical Engineering, Sharif University of Technology, Tehran
Abstract:
The issues related to non-invasive BPM methods/devices are mainly due to cuff application including 1) size incompatibility, 2) malpositioning, 3) inappropriate deflation rates, 4) patient anxiety, 5) patient discomfort while sleeping all of which contribute to inaccurate measurement. To resolve these issues cuff-less blood pressure monitoring devices are being developed. Almost all of the cuff-less blood pressure measurement devices implement pulse arrival time (PAT) with electrocardiography (ECG) as the time reference. The PAT is described as the phase interval between the R-peak of QRS complex and the arrival of the arterial pulse wave. PAT is measured with 1) single lead ECG as a patch on the chest or wrist or as a belt, 2) finger or ear photoplethysmography (PPG), and 3) integrated 3-D acceleration sensor. The aim of this presentation is to review recent advancement in cuff-less non-invasive blood pressure monitoring devices for clinical and home applications.
