The quantitative fit test was performed using the Porta-Count Plus.
(a) Cup-type respirator, which is preformed to a cup shape. (b) Fold-type respirator, which is flexible and free-folded. (c) Macintosh laryngoscope, which has a size 4 curved blade with a Satin Slip stylet. (d) GlideScope® with a GlideRite rigid stylet. (e) I-gel® airway device.

Fit factor values for the two types of N95 respirator when used for intubation using three types of airway device.
The fit factor value for the valve type was decreased during intubation. There were significant differences between the fit factor values for the cup-type respirator and the fold-type respirator when intubations were performed using the three different airway devices. ∘Outlier value more than 1.5 times the upper or lower limit.
