Can a valved respirator be used for protection from SARS?
According to the infection control guidelines for SARS, as developed by the CDC, WHO and Health Canada an N95 respirator is recommended to help provide respiratory protection for healthcare workers. A valved respirator is designed to allow for easy exhalation through a one-way exhalation valve. If a person is wearing a respirator to reduce his or her exposure to SARS, a respirator with an exhalation valve would be acceptable. It would not be acceptable for someone to wear a valved respirator if they are suspected/probable/confirmed case of SARS, as they would be exhaling into the environment. For other situations where healthcare workers are required to wear a respirator the use of a valved respirator must be in accordance with national guidelines. For example, in some regions of the world such as the US and Canada, it is not acceptable for a healthcare worker to wear a valved respirator in a situation requiring a sterile environment, such as the operating room.
