Document Summary
Subdivisions of lung volumes; minute ventilation; alveolar ventilation; and. Work of breathing: name the different subdivisions of lung volumes. Tidal volume the volume of air entering or leaving the lungs in a single breathe . Inspiratory reserve volume (irv) the extra volume that can be maximally inspired. Inspiratory capacity (ic) the total volume that can be inspired. Expiratory reserve volume (erv) the maximum volume that can be expired. Residual volume (rv) the volume of air remaining after maximum expiration. Functional residual capacity (frc) the volume of air in the lungs at the end of a normal passive expiration. Vd anatomical dead space does not participate in gas exchange but are full of air during expiration and inspiration: state the difference between a volume and a capacity The capacity is the sum of two or more lung volumes: types of expiratory flow. Dynamic lung function can be assessed if suspected of having pulmonary problems.
