For patients with isolated left main (LM) coronary artery disease, pressure-based physiological testing—whether by fractional flow reserve (FFR) or instantaneous wave-free ratio (iFR)—reveals ...

Using dry nitrogen to pressure test a system is a very effective method of verifying a system is leak-free. In fact, I believe it is more reliable than using a standing vacuum test typically performed ...

WASHINGTON, DC—Invasive hemodynamic assessment may help better identify severe aortic stenosis in patients with low aortic flow/low transvalvular pressure gradients and preserved ejection fractions, ...

Pressure-depth plots are powerful methods to visualize the wide array of industry pressure data and aid interpretation for safety, drilling, and exploration purposes. Pressure-depth plots and ...

The petroleum industry must predict pore-pressure profiles accurately, often walking a fine line between pore pressure and fracture gradient as it drills and completes oil and gas wells. The industry ...
