Explanation: A ventilator is a lung machine that breathes for a patient who cannot breathe on his or her own. Postural drainage places the patient in a position so that gravity can help facilitate drainage of fluids. Endotracheal intubation is the placing of a tube through the mouth, through the glottis, and into the trachea to create a patent airway. Aerosol therapy is medication suspended in a mist that is intended to be inhaled into the lungs.
