Certified and able to perform standard cardiopulmonary resuscitation for delivery of basic life support or advanced cardiovascular support, those who have completed an accredited institutional training program, and those who perform cardiopulmonary resuscitation in the clinical field. 4. Healthcare workers who obtained a pass of fit tests for one of the traditional N95 respirators (best-fit one) as well as new respirators in the phase1 study

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Real-time leakage is measured by two portable aerosol spectrometers by factoring the difference in small particles (0.3µm) between ambient and inside respirators at an average of 30 s intervals while performing cardiopulmonary resuscitation. A total of eight sets within a 4 min procedure. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Fit rate, which is the proportion of fit factor >100 among total samples with a given respirator measured by a PortaCount respirator fit-tester system (model Pro+ 8038/8040; TSI limited) 2. Mask usability measured using an 11-item Mask Usability Scale to measure wearers' personal feedback on a donned respirator measured at a single time point | — |
