Journal ArticleDOI
Exhaled air dispersion during high-flow nasal cannula therapy versus CPAP via different masks.
David S.C. Hui,Benny K. Chow,Thomas Lo,Owen Tak-Yin Tsang,Fanny W.S. Ko,Susanna S.S. Ng,Tony Gin,Matthew T. V. Chan +7 more
TL;DR: Exhaled air dispersion from high-flow nasal cannula (HFNC) and CPAP is limited provided there is good mask interface fitting, however, exhaled air leakage to 620 mm laterally occurs when the connection between HFNC and the interface tube becomes loose.
Journal ArticleDOI
Noninvasive Positive-Pressure Ventilation
David S.C. Hui,Stephen D. Hall,Matthew T. V. Chan,Benny K. Chow,Jin Yeu Tsou,Gavin M. Joynt,Colin E. Sullivan,Joseph J.Y. Sung +7 more
TL;DR: Substantial exposure to exhaled air occurs within a 0.5-m radius of patients receiving NPPV, and medical wards should be designed with an architectural aerodynamics approach and knowledge of air/particle dispersion from common mechanical ventilatory techniques.
Journal ArticleDOI
Noninvasive positive-pressure ventilation: An experimental model to assess air and particle dispersion.
David S.C. Hui,Stephen D. Hall,Matthew T. V. Chan,Benny K. Chow,Jin Yeu Tsou,Gavin M. Joynt,Colin E. Sullivan,Joseph J.Y. Sung +7 more
TL;DR: In this paper, an oronasal mask attached to a human-patient simulator (HPS) during noninvasive positive-pressure ventilation (NPPV) was used for visualization.
Journal ArticleDOI
Exhaled air dispersion during coughing with and without wearing a surgical or N95 mask.
TL;DR: N95 mask was more effective than surgical mask in preventing expelled air leakage during coughing but there was still significant sideway leakage.
Journal ArticleDOI
Exhaled Air Dispersion Distances During Noninvasive Ventilation via Different Respironics Face Masks
David S.C. Hui,Benny K. Chow,Susanna S.S. Ng,Leo Chu,Stephen D. Hall,Tony Gin,Joseph J.Y. Sung,Matthew T. V. Chan +7 more
TL;DR: Substantial exposure to exhaled air occurs within a 1-m region, from patients receiving NPPV via the ComfortFull 2 mask and the Image 3 mask, with more diffuse leakage from the latter, especially at higher IPAP.
