Cuff-free Blood Pressure Estimation Using Signal Processing Techniques
Since blood pressure is a significant parameter to examine people’s physical attributes and it is useful to indicate cardiovascular diseases, the measurement/estimation of blood pressure has gained increasing attention. The continuous, cuff-less and non-invasive blood pressure estimation is required for the daily health monitoring. In recent years, studies have been focusing on the ways of bloo...
متن کاملThe dicrotic arterial pulse.
SUMMARY The study consisted of observations on nine male patients with palpable dicrotic carotid pulses. Average patient age was 37 years. All had advanced myocardial failure as evidenced by cardiomegaly and the presence of prominent atrial and ventricular diastolic gallop sounds. Most of these patients were diagnosed as having primary myocardial disease. The indirect carotid pulse was characte...
متن کاملReduction of false arterial blood pressure alarms using signal quality assessment and relationships between the electrocardiogram and arterial blood pressure.
The paper presents an algorithm for reducing false alarms related to changes in arterial blood pressure (ABP) in intensive care unit (ICU) monitoring. The algorithm assesses the ABP signal quality, analyses the relationship between the electrocardiogram and ABP using a fuzzy logic approach and post-processes (accepts or rejects) ABP alarms produced by a commercial monitor. The algorithm was dev...
متن کاملFPGA Based Digital System for Detection of Dicrotic Notch in the Carotid Pulse Signal
Heart disease is one of the leading causes of death in human beings. A survey shows every year about 900,000 peoples die due to heart diseases worldwide. Carotid pulse is a pressure signal recorded over the carotid artery as it passes near the surface of the body at the neck. An abnormal carotid pulse called the dicrotic pulse occurs when patients suffer from sepsis, hypovolemic shock, cardiac ...
