For years, difficulty in breathing caused by constricted air passages has been managed and treated by the use of the nebulizer. As you know, a nebulizer is a device that converts the liquid medicine into mist or aerosol form. The vapors are then inhaled by the patient through a mask or a mouthpiece so the medication will be delivered directly to the lungs. It is a device that is often seen in emergency rooms and emergency vehicles so that the healthcare practitioners would be able to dilate the air passages of the patient that cannot breathe ideally. It is one of the priorities in rescuing a life. Breathing should be stabilized and helped so that the oxygenation of the brain and the rest of the body will continue as the heart pumps blood.
