Noninvasive Mechanical Ventilation: Models to Assess Air and Particle Dispersion 2013-05-29 .txt text/plain 3687 166 49 particles generated during tidal breathing [ 8 ] , NIV may disperse potentially infected aerosols, especially when patients cough and sneeze frequently, contributing to nosocomial transmission of infl uenza. As there is no reliable, safe marker that can be introduced into human lungs for experimental purposes, the laser smoke visualization method and the human patient simulator (HPS) model have been adopted as the method for studying exhaled air dispersion during application of various types of respiratory therapy in hospital medical wards, including the negative-pressure isolation room [ 10 -13 ] . Sections through the leakage jet plume were then revealed by a thin, green laser light sheet (532 nm wavelength, continuous-wave A laser beam located on the right side of the bed lateral to the human patient simulator illuminates the exhaled air particles leaking from the exhalation ports of the face mask in the coronal plane. ./cache/cord-016744-jzhuq4te.txt ./txt/cord-016744-jzhuq4te.txt
