The years 2020-21 are some of the most challenging years experienced by humankind. While the people of Earth recover from the hard blow of COVID-19, they also witnessed several large-scale wildfires. As a result, we observed both the positive and negative impacts on the ambient air quality. The wildfire occurrences severely deteriorated the air quality. In contrast, country-wide complete and ...
However, the risk of nosocomial infection is unknown. Methods: We examined exhaled air dispersion during NIV using a human patient simulator reclined at 45° in a negative pressure room with 12 air changes/h by two different helmets via a ventilator and a total facemask via a bilevel positive airway pressure device. Exhaled ...
The newly updated atmospheric dispersion model RIMPUFF is evaluated using routine releases of 41Ar from the former HIFAR research reactor located in Sydney, Australia. ...
Abstract Background: As part of our influenza pandemic preparedness, we studied the exhaled air dispersion distances and directions through two different face masks (Respironics; Murrysville, PA) attached to a human-patient simulator (HPS) during noninvasive positive-pressure ventilation (NPPV) in an isolation room with pressure of -5 Pa. ...
