Nurses had a qualitative fit testing using the saccharin or Bitrex protocol. All 11 had laboratory-confirmed influenza. This standard does not require that the respirator be resistant to ; another standard, P95, adds that requirement. For aerosol-generating procedures such as intubation or bronchoscopy , as long as tuberculosis was not suspected, nurses continued to use the respiratory device they were assigned to.
