RESPIRATORY DEFINITIONS

1. the sharp pointed cartilage at the bifurcation of the right and left mainstem bronchi
3. respired gas volume that does not participate in gas exchange
4. an acute or chronic inflammation of the mucous membranes of the tracheobronchial tree
5. a substance, especially a drug, that relaxes contractions of the smooth muscle of the bronchioles to improve ventilation to the lungs
8. a destructive process of the lung parenchyma leading to permanent enlargement of the distal air spaces
10. an abnormal condition of the bronchial tree characterized by irreversible dilatation and destruction of the bronchial walls
11. an infectious disorder of the upper airway occurring chiefly in infants and children that normally results in subglottic swelling and obstruction

9. bulbous swelling of the terminal phalanges of the fingers and toes, often associated with certain chronic lung diseases
10. a spontaneous breath mode of ventilatory support which allows separate regulation of the inspiratory and expiratory pressures
