This study carried out an investigation on the use of two respirators (fold- and cup-type) by physicians (n=26) as protection against infections during intubation procedures with three different devices (DL, GlideScope and i-gel). Results showed a lower protection level when wearing the cup-type respirator during intubation with DL (75%) compared to GlideScope (100%) and i-gel (100%). Therefore, the type of airway device selected for intubation may impact on the level of protection of certain types of respirators. However, due to the limited number of respirators tested and the small sample size, additional larger studies are needed to validate these results.
