Cardiac Pressures and Pulses. [PDF]

open access: yesArchives of Internal Medicine, 1957
This small book by Luisada and Liu summarizes in 109 pages aspects of hemodynamic cardiac phenomena obtained by cardiac catheterization with the Fick principle for recording variations in cardiac output and pressure. The monograph includes a discussion, in more or less conventional fashion, of the cardiac cycle, technique of catheterization, normal ...

A continuous discharge improves the performance of the Cu/CuCl double pulse laser [PDF]

open access: yes, 1979
A continuous glow discharge was applied to a Cu/CuCl double pulse laser. Maximum laser pulse energy was observed to increase as much as 35 percent at low buffer gas pressure and 3.5 percent at optimum buffer gas pressure.

Pressure Pulse in Small Arteries [PDF]

open access: yesCirculation Research, 1962
Pressure pulse contours have been obtained in the small mesenteric and intestinal arteries of the dog. The principal change in the pressure pulse during transmission from large to small arteries appeared to be the gradual and progressive development of damping. The pressure drop from the aorta to arteries of 200 µ internal diameter averaged 17 per cent

Effect of pulse pressure on borehole stability during shear swirling flow vibration cementing. [PDF]

open access: yesPLoS ONE, 2017
The shear swirling flow vibration cementing (SSFVC) technique rotates the downhole eccentric cascade by circulating cementing fluid. It makes the casing eccentrically revolve at high speed around the borehole axis.

Wearable Multi-Channel Pulse Signal Acquisition System Based on Flexible MEMS Sensor Arrays with TSV Structure

open access: yesBiomimetics, 2023
Micro-electro-mechanical system (MEMS) pressure sensors play a significant role in pulse wave acquisition. However, existing MEMS pulse pressure sensors bound with a flexible substrate by gold wire are vulnerable to crush fractures, leading to sensor ...

Pulse pressure as a predictor of stroke [PDF]

open access: yesExpert Review of Neurotherapeutics, 2008
The current guidelines for the detection and management of high blood pressure depend exclusively on the measurement of systolic and diastolic blood pressure, although these are only two specific p...
