An apparatus includes a garment to be worn by a patient and a plurality of mechanical percussors carried by the garment. The plurality of mechanical percussors provide percussive forces onto a patient's thorax in order to dislodge mucous buildup in the airways and encourage expectoration of the mucous. The apparatus further includes a controller connected to the garment. The apparatus also includes an electrically operated nebulizer unit that removably attaches to the controller. The controller commands the operation of the mechanical percussors and provides power to the nebulizer unit.
