A breathing assistance device includes a patient breathing tube in fluid communication with a face mask. A source of air connected to a first port formed integrally with a valve in fluid communication with the breathing tube and a nebulizer is connected to a second port formed integrally with the valve. A reservoir holding medicine in liquid form is connected to the nebulizer. A valve actuator has an open configuration where gaseous fluid and aerosolized medicine from the nebulizer flow to the patient through the breathing tube and a closed configuration where only gaseous fluid is delivered. Medication can, therefore, be selectively administered to the patient by manipulating the valve actuator. The valve enables the patient to exhale against pressure slightly above atmospheric pressure. Filter device is secured to the valve body and is configured to filter contaminates from a patients exhaled breath prior to being exhausted into the environment.
