Discuss the composition of minute ventilation
WebJul 5, 2024 · There are two equations needed to calculate the volume that enters the lungs and the volume that reaches the alveoli. The volume that enters the lung per minute is known as minute ventilation (VE). The equation states VE equals tidal volume (VT) multiplied by respiratory rate (RR). 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 atmosphere and by which the carbon dioxide carried into the lungs in the mixed venous blood is expelled from the body.
