Comparison of Various Blood Pressure Measurement Techniques with Standard Office Based Blood Pressure Mesurement

Introduction: In order to control Hypertension, it is necessary to understand the methods of blood pressure measurement. Recent guidelines emphasize on employing appropriate blood pressure measurement techniques and white coat hypertension. Definition and methods of blood pressure measurement have changed in the American guideline based on SPRINT trial (Systolic Blood Pressure Intervention Tria...

Chronobiological analysis techniques. Application to blood pressure.

Most variables of clinical interest show predictable changes with different frequencies, mainly, but not exclusively, along the rest-activity cycle (circadian variation). Methods of linear least-squares estimation have been designed for the detection of periodic components in sparse and noisy time series (as they are usually present in clinical situations). They include the single and populatio...

Blood Pressure Determination Using Analysis of Biosignals

The paper deals with an analysis of biosignals for the purpose of non-invasive blood pressure monitoring without the necessity of using a pneumatic cuff. The method of simultaneous recording of electrocardiogram (ECG) and photoplethysmogram (PPG) and evaluations of their mutual time shift, which corresponds to the pulse transit time (PTT), are described in the paper. Results of original and imp...

Oscillometric 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...
