the amount of air in excess of tidal volume that can be inhaled with maximum effort is the __________.
It is calculated by multiplying the tidal volume by the normal breathing rate per minute.[500Ã12= 6000ml/mt]. 8. The alveolar ventilation rate [AVR] is the volume of air per minute that reaches the alveoli. 9. Inspiratory reserve volume (IRV)[3,000 mL]:- Amount of air in excess of tidal inspiration that can be inhaled with maximum effort. Expiratory reserve volume (ERV)[1,200 mL]:- Amount of air in excess of tidal expiration that can be exhaled with maximum effort. Residual volume (RV)[1,300 mL]:-Amount of air remaining in the lungs after maximum expiration; keeps alveoli inflated between breaths and mixes with fresh air on next inspiration. 10.
