Pulse Wave Analysis Digital Plethysmography Finger Plethysmography Accelerated Plethysmography Clinical Bottom Line - The Simple Explanation
The digital plethysmograph is a secondary output of the pulse oximeter, which is commonly used to measure arterial blood saturation (SaO2)61. Digital plethysmography provides noninvasive, continuous, and real-time measurement of arterial pressure with infrared light transmitted through a digit (finger or toe)62. This technique acquires the digital volume pulse (DVP), a waveform that estimates p...
متن کاملProblems of Measuring Pulse Wave Velocity
Problems of measuring pulse wave velocity and its utilization in diagnostics have been examined for many years. Pulse wave velocity is a quantity that can be measured non-invasively, and it may bring much information about the state of circulatory system. The R-wave of electrocardiogram (ECG) is most frequently used as the reference point for measuring the pulse wave velocity but it can also be...
متن کاملPulse Wave Analysis and Pulse Wave Velocity
momanometer that provides arterial pressures (brachial systolic and diastolic pressure) is coming under question. The concerns extend well beyond the familiar issue of “white coat” hypertension, home and 24-h blood pressure recordings, and the phase-out of mercury based instruments. These concerns relate to the inaccuracy of all cuff devices for measuring pressure within the brachial artery, th...
متن کاملPulse wave velocity measurement
The article deals with the investigation of pulse wave propagation in arteries. A part of work involves also design and realization of devices serving for scanning of pulse wave by reflective photoplethysmography. The work describes a use of microcontroller serving for data flow control, communication and analog signal digitalization using integrated analog to digital converter.

1872-9312/$e seefrontmattera2008A doi:10.1016/j.artres.2008.11.002 Summary Measurement of pulse wave velocity is of increasing importance for assessment of arterial stiffness and risk evaluation. Different techniques are available, based either on pressure, distension or Doppler waveforms. Techniques not only differ by the algorithm used to identify specific part of the pulse signal, but also i...
