Total lung capacity is:
Correct Answer: 6 --7 litres
Description: Ans. C. 6--7 litersImportant parameters of lungs: -a. Vital capacity =IRV+TV+ERV= Inspiratory capacity +ERVb. Inspiratory capacity =IRV+TVc. Functional residual capacity =ERV+RVd. Respirator minute volume or Pulmonary ventilation = 6 L/mine. Alveolar ventilation (at rest) = 4.2 L/minf. Maximal voluntary ventilation (BTPS) 125 -- 170 L/ming. Timed vital capacity: - 80% of total in 1 second; 97% in 3 secondsh. Work of quite breathing: - 0.5 kg-m/min.i. Maximal work of breathing: - 10kg-m/breathj. TV = 150mL (dead space) + 350 (Alveolar volume) = 500 ml
