Check the gap: Facemask performance and exhaled aerosol distributions around the wearer.

open access: yesPLoS ONE, 2020
Current facemask research focuses on material characterization and efficiency; however, facemasks are often not tested such that aerosol distributions are evaluated from the gaps in the sides, bottom, and nose areas. Poor evaluation methods could lead to

Pre-oxygenation in obese patients: facemask versus facemask with nasal prong

open access: yesMalaysian Journal of Anaesthesiology, 2023
Introduction: Anatomical and physiological changes of the respiratory system in obese patients predispose them to rapid oxygen desaturation during apnoea. Adequate pre-oxygenation before anaesthesia induction allows a period of safe apnoea. The efficacy of pre-oxygenation with facemask versus facemask with nasal prong was compared.

Smart facemask for wireless CO2 monitoring

open access: yesNature Communications, 2022
AbstractThe use of facemasks by the general population is recommended worldwide to prevent the spread of SARS-CoV-2. Despite the evidence in favour of facemasks to reduce community transmission, there is also agreement on the potential adverse effects of their prolonged usage, mainly caused by CO2 rebreathing.
