A dual area pressure pulmonary modulator apparatus which provides constant flow, pressure cycled ventilatory support to patients. The pressure pulmonary modulator apparatus opens at a selected pressure and shuts at a substantially lower pressure. The pressure pulmonary modulator apparatus can be incorporated into an automatic resuscitator suited for providing ventilatory support during resuscitation and/or transport of patients. The automatic resuscitator may be combined with a nebulizer to serve as a positive pressure aerosol therapy device. The pressure pulmonary modulator apparatus can also be incorporated into a percussive therapy device used for the mobilization of mucus in patients. The pressure pulmonary modulator apparatus may be made almost entirely of injection molded plastic and is inexpensive, portable and disposable. |
