The cardiac output monitoring devices based on pulse wave analysis (PWA) became a standard of hemodynamic management in many selected patients in critical and perioperative care. They are known as “minimally invasive” because the only prerequisite is a conventional arterial catheter.

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2004
Pulsed wave interconnect is proposed for global interconnect applications. Signals are represented by localized wave-packets that propagate along the interconnect lines at the local speed of light to trigger the receivers. Energy consumption is reduced through charging up only part of the interconnect lines and using the voltage doubling property of ...

Ultrashort-pulse wave-front autocorrelation
Optics Letters, 2003Combined spatially resolved collinear autocorrelation and Shack-Hartmann wave-front sensing of femtosecond laser pulses is demonstrated for the first time to our knowledge. The beam is divided into multiple nondiffracting subbeams by thin-film micro-optical arrays. With hybrid refractive-reflective silica/silver microaxicons, wave-front autocorrelation

CAROTID‐FEMORAL PULSE WAVE VELOCITY*
Journal of the American Geriatrics Society, 1968A bstract Simultaneous records of the pulse waves were obtained from the right common carotid artery and the right femoral artery by means of piezo‐electric microphones in 26 persons whose ages ranged from 15 to 92 years.

PULSE WAVE ANALYSIS IN HISTORICAL TIMES: Interpretation of the arterial pulse has been an important part of the medical examination from ancient times. Graphic methods for clinical pulse wave recording were introduced by Marey in Paris and by Mahomed in London last century.

This was what Mahomed wrote, in 1872. He was a man of genius of the end of the 19th century, and he is considered to be the pioneer of pulse wave analysis [10]. After the first enthusiasm regarding pulse wave analysis, it fell into disuse, mainly for two reasons: first, the young Mahomed died before his time; second, Riva-Rocci introduced his ...

Pulse wave velocity (PWV) reflects arterial stiffness. PWV correlates with other markers reflecting the severity of atherosclerosis such as the findings of ultrasound examination of carotid artery. In addition, several studies demonstrated that increased PWV is a predictor of future cardiovascular events in patients with either hypertension or diabetes

Wave Travel and Pulse Wave Velocity
2018Waves generated by the heart travel down the aorta and major conduit arteries. These waves are pressure waves, flow or velocity waves or diameter waves. The ratio of the distance Δx, and the time it takes for the foot of the wave to travel over this distance, Δt, gives the wave speed or pulse wave velocity, PWV=Δx/Δt.
