Abstract |
Several types of respirator were compared with respect to efficacy against penetration of infectious droplet nuclei capable of carrying Mycobacterium tuberculosis bacilli. Powered air-purifying respirators (PAPRs) with elastomeric halfmask facepieces and high efficiency (HEPA) filters provided substantially better protection than did surgical masks and disposable dust/mist particulate respirators. This greater protection is related to the PAPR's relatively high filtration efficiency and the low degree of facial leakage. When droplet nuclei source control is inadequate, healthcare workers may need to wear highly protective respirators for protection against tuberculosis infection. |
