Safeguards to reduce the risk of droplet transmission of infectious agents suspended in droplets larger than 5 microns. Designed to protect the mucosal surfaces of the mouth, respiratory tract and eyes. Droplets are generated from source persons by speaking, coughing and sneezing as well as several procedures (e.g. tracheal suctioning and bronchoscopy). It is estimated that droplets this size fall out of the air at a distance of 3-6 feet from the source patient. Thus, a mask should be worn when a provider will be that close to the patient.
