Abstract: Apparatus and method for the simultaneous administration of pressurized oxygen, a nebulized mist of bronchodilator, and an additional liquid medicant into the trachea and lungs of a patient exhibiting little or no respitory function. The oxygen is fed through a tube from a manually operable resuscitator such as an Ambu-Bag. The nebulized bronchodilator is fed from a conventional nebulizer into the tube carrying oxygen from the resuscitator. The additional liquid medicant is fed from the needle of a pre-filled syringe containing the liquid medicant directly into the tube carrying pressurized oxygen and the mist of nebulized bronchodilator. The tube carrying the oxygen, the bronchodilator and the additional liquid medicant is connected to the upper end of an endotracheal tube which terminates in the patient's trachea.
