Abstract
An aerosol inhalation system includes a single source of gas; a connector and an accessory having a main conduit body. A nebulizer is sealingly and removably coupled to the main conduit body. A supplemental gas inlet port is in fluid communication with the connector for introducing a flow of supplemental gas from the single gas source to the patient under select conditions. The gas from the gas source that flows to the supplemental gas inlet port passes through a flow metering member that is remote from the supplemental gas inlet port that controls the flow rate of the supplemental gas to the patient interface. The flow rate of the gas through the supplemental gas inlet port is different than a gas flow rate into the nebulizer for generating the aerosolized medication.
