WebAlveolar ventilation is the exchange of gas between the alveoli and the external environment. It is the process by which oxygen is brought into the lungs from the … WebRemember that tidal volume is the sum of dead space volume and alveolar volume, so in this diagram 500mL of tidal volume will be composed of 150mL dead space volume and 350mL alveolar volume. Hence, we can deduce alveolar ventilation by multiplying respiratory rate (15/min) and alveolar volume (350mL) to get 5250mL/min.

WebAt the steady state, the rate of production of CO 2 equals the net rate at which it is exhaled from the body, which (assuming no CO 2 in the ambient air) is the product of the alveolar ventilation and the end-tidal CO 2 concentration. Because of this interrelationship, the set of possible steady states forms a hyperbola: hotel transylvania party suppliesWebMinute ventilation (or respiratory minute volume or minute volume) is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person's lungs per minute.
