N95 respirator OR Surgical mask ⁉️
🔶 Conflicting recommendations exist related to which facial protection should be used by health care workers to prevent transmission of acute respiratory infections, including pandemic influenza.
🔷 Meta-analysis of 6 clinical studies (3 RCTs, 1 cohort study and 2 case–control studies) indicates NO difference between N95 respirators and surgical masks in risk of👇
❎ laboratory-confirmed respiratory infection
❎ influenza-like illness
❎ reported workplace absenteeism
🔷 Meta-analysis of 23 surrogate exposure studies reveals to us that under laboratory experimental conditions, N95 respirators are associated with less 👇
✅ filter penetration
✅ face-seal leakage
✅ total inward leakage
