The Comparison of the Measurements at Two Time Points with Medical Mask and Type II Filtering Facepiece Respirator
| Index | Medical Mask, Median (IQR) (n = 153) | Medical Mask + FFP2, Median (IQR) (n = 153) | p Value |
|---|---|---|---|
| MAP, mm Hg | 90.3 (87.7–97.5) | 93.7 (88.5–96.5) | 0.001 |
| HR, beats/min | 82.0 (75.0–92.0) | 86.0 (74.0–92.5) | 0.973 |
| RR, breaths/min | 14.0 (12.0–16.0) | 16.0 (14.0–17.0) | < 0.001 |
| SatO2, % | 99.0 (99.0–100.0) | 99.0 (98.0–99.0) | 0.005 |
| ETCO2, mm Hg | 36.4 (35.1–38.3) | 38.8 (36.2–45.3) | < 0.001 |
| Dyspnea (VAS), cm | 2.0 (1.0–3.0) | 4.0 (3.0–5.0) | < 0.001 |
ETCO2 = end-tidal carbon dioxide; FFP2 = type II filtering facepiece respirator; HR = heart rate; IQR = interquartile range; MAP = mean arterial pressure; RR = respiratory rate; VAS = 1–10 cm visual analog scale.
