An airway device having a first passage open at one end to the atmosphere and carrying a mouthpiece at the other end through which a patient may breathe. A second passage opens into the first passage for communication with the outlet of a medication nebulizer. The airway device also has a tubular section extending into the first passage for communication with the negative air pressure sensing port of a positive pressure breathing machine which upon sensing inhalation by the patient causes actuation of the nebulizer to apply the nebulized medication through the airway device to the patient's lungs during the inhalation phase only of each breathing cycle while allowing the patient to breathe freely into the atmosphere. |
