Nasal Wipes for Influenza A Virus Detection and Isolation from Swine

Using half-facepiece respirators for H1N1
Abstract:
A respirator is a device designed to help provide the wearer with respiratory protection against inhalation of airborne contaminants. Increasing the filtration level of a particle respirator does not increase the respirator's ability to reduce a user's exposure to contaminants. The APF of a respirator, which is affected by the respirator style, determines the potential for exposure reduction. Surgical masks that are not approved as filtering facepiece half-mask respirators do not have an APF and should not be used for reducing workers' exposures to particles in the air.

Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
