Aerosol Deposition in the Human Lung at Variable Tidal Volumes: Calculation of Fractional Deposition

Abstract

The calculation of fractional aerosol deposition in the data against the ratio of volume exhaled to volume human lung and methods for correction of breath-byinhaled give linear plots of similar slope for a range of breath deposition data for inequalities in tidal volunie are steady state breathing patterns for both 0.5-and 1.2-pm discussed. Three different methods are considered. Steady particles. Semiempirical algebraic correction factors are state and wash-in curves are used to evaluate methods found to be suitable for analysis of wash-in curves. presented herein. Plots of breath-by-breath deposition

Nitric Oxide Ventilation Improves Recirculation and Right Ventricular Function During Veno-Venous Extracorporeal Membrane Oxygenation in a COVID-19 Patient

“…As demonstrated in earlier studies, and perhaps illustrated by the limited response in our patient, aerosolized therapy in mechanically ventilated patients might not be as effective due to high drug-losses in the ventilator components, and subsequent low lung drug delivery (varying between 1-10% in vitro and vivo). 19 Moreover, reduced V T ’s could even attenuate this effect and should therefore be ideally >500mL, 20 , 21 which can potentially be harmful to this patient category.…”
