Squeezing the nebulizer bulb incorrectly (using 2 fingers) results in an inadequate challenge aerosol concentration. Proper squeezing of the nebulizer bulb requires the bulb to be completely…
This video shows how excessive tilting of nebulizers used for respirator fit testing fails to generate a sufficient aerosol challenge concentration. When this happens, poorly fitting respirators can…
Clogging of nebulizers used during qualitative respirator fit testing (QLFT) are a common occurrence. This video provides explains how to check nebulizers for clogging prior to the start and end of…
