Oscillometric Continuous Blood Pressure Sensing for Wearable Health Monitoring System
In this paper we present an acquisition chain for the measurement of blood arterial pressure based on the oscillometric method. This method does not suffer from any limitation as the well-known auscultatory method and it is suited for wearable health monitoring systems. The device uses a pressure sensor whose signal is filtered, digitalized and analyzed by a microcontroller. Local analysis allo...
متن کاملMonitoring Personalized Trait Using Oscillometric Arterial Blood Pressure Measurements
The blood pressure patterns obtained from a linearly or stepwise deflating cuff exhibit personalized traits, such as fairly uniform peak patterns and regular beat geometry; it can support the diagnosis and monitoring of hypertensive patients with reduced sensitivity to fluctuations in Blood Pressure BP over time. Monitoring of personalized trait in Oscillometric Arterial Blood Pressure Measurem...
متن کاملRapid oscillometric blood pressure measurement compared to conventional oscillometric measurement.
BACKGROUND There have been few reports studying the necessary interval between blood pressure measurements, after the initial rest period. METHODS Blood pressure was measured in 50 patients using the conventional oscillometric technique (COT) and the rapid oscillometric technique (ROT). RESULTS The difference between COT and ROT was -1.1 / -0.1 mmHg, which was not significantly different (p...
متن کاملOscillometric wrist blood pressure measuring devices.
Devices measuring blood pressure oscillometrically at the wrist are becoming more and more popular. These devices are small, easy to handle and can measure blood pressure without the need to undress. However, few of the wrist devices have been validated properly, i.e. according to internationally accepted protocols. In this article current literature on wrist blood pressure measuring devices is...
متن کاملOscillometric blood pressure measurements: A signal analysis
In this paper, the oscillometric waveform measured by automatic non-invasive blood pressure meters (NIBP) is analyzed by transforming the data from the time domain to the frequency domain. The signal’s spectrum of the oscillometric waveform is in current literature badly understood or explored. The only known link between the oscillometric waveform and the blood pressure is the maximum of the o...
