Understanding why, when, and how to use a respirator is more complicated than operating the respirator itself. "The clinicians want to be safe. Performance of an N95 filtering facepiece particulate respirator and a surgical mask during human breathing: two pathways for particle penetration. Another moment of overstretched capacity and really one of tragic and often preventable sadness," Walensky said, as she thanked health-care workers for their service during the repeated surges of illness they have confronted since the Covid pandemic began.
