How does ventilation work in the lungs
WebJul 5, 2024 · Ventilation is the manner by which air enters the lungs. 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). WebSep 26, 2024 · Ventilation is the process that moves air into and out of the alveoli, and perfusion affects the flow of blood in the capillaries. Both are important in gas exchange, as ventilation must be sufficient to create a high partial pressure of oxygen in the alveoli.
