Pressure pulsations enhance penetration index in COPD

Drug Delivery and Translational Research, 2021
This study was done in order to evaluate the effect of a novel pressure pulsation device (Pulsehalerâ„¢, Respinova Ltd., Israel) on the deposition pattern of inhaled aerosol in the lungs of COPD patients. Fifteen COPD patients were recruited to undergo spirometry and SPECT-CT lung scan following nebulization of radioactively labeled albuterol in saline ...

Rheodynamic model of cardiac pressure pulsations

Mathematical Biosciences, 1999
To analyse parametrically (in terms of the qualitative theory of dynamical systems) the mechanical influence of inertia, resistance (positive and negative), elasticity and other global properties of the heart-muscle on the left ventricular pressure, an active rheodynamic model based on the Newtons's principles is proposed. The equation of motion of the

Pressure Pulsation in Solid-Phase Fermentation

Applied Biochemistry and Biotechnology, 2002
Inadequate dissipation of heat generated by biologic activities has prevented the use of solid-phase fermentation in large-scale applications. This study deals with the cooling effects of pressure pulsation on solid, porous beds. Pressure pulsation also enhances evaporation of medium moisture, which is also described.
