(Kemp JP, Skoner D, Szefler SJ, et al. Ann Allergy Asthma Immunol. 1999;83:231–239). This study retrospectively examines the data more closely and demonstrates that efficacy and safety are not dependent on whether administration is by facemask or mouthpiece. The results here provide reassuring data for clinicians treating children with persistent asthma who are too young to use mouthpieces. Sim...

Before 1990, the choice of an airway device essentially was limited to the facemask or the endotracheal tube. Since then, a number of novel supraglottic airway devices have been developed. The laryngeal mask airway (LMA) was introduced to the United States in 1991 after 3 years of use in the United Kingdom and other countries. Today the LMA has a clearly established role as an airway device in ...

In December 2019, the SARS-CoV-2 virus emerged and rapidly spread throughout world. It causes respiratory disease COVID-19 via transmission of microbial pathogens within bio-aerosols during speaking, sneezing, coughing. Therefore, understanding bioaerosol dynamics is important for developing mitigation strategies against droplet-induced infections. Computer modelling, using Computational Fluid ...
