What situations other than breathing move air into or out of may modify normal respiratory breathing?
Mechanical… Mechanical ventilation is the use of a machine to induce alternating inflation and deflation of the lungs, to regulate the exchange rate of gases in the blood. The most common type of ventilator (or respirator) delivers inspiratory gases directly into the person’s airway. The patient is connected to the ventilator by a endotracheal tube passed through the nose or mouth into the trachea (windpipe). If prolonged ventilation is likely to be required, a tube is inserted into an opening made in the trachea, an operation called a tracheostomy. The cough assist is used with a facemask, mouthpiece or, with an adapter, to a patient’s endotracheal or tracheostomy tube. This device can be used on adult and pediatric patients at home or in a hospital/institutional environment. Nasal obstruction and nasal anesthesia result in disordered breathing during sleep in humans. Upper airway dilating muscle activity may be modulated by superficial receptors in the nasal mucosa sensitive to air
