What is the difference between pulmonary ventilation and alveolar ventilation?

summary

Some time ago, I was still eating a big fish and meat diet. During this time, I always felt that the lung was a little uncomfortable. The speed and volume of air were not as usual. Later, I checked online to find out the difference between lung ventilation and alveolar ventilation. What's the difference between lung ventilation and alveolar ventilation?

What is the difference between pulmonary ventilation and alveolar ventilation?

All the amount of air absorbed by the lungs of the human body. Compared with lung volume, it can reflect lung ventilation function more comprehensively. Minute ventilation volume: minute lung ventilation volume refers to the total amount of gas inhaled or exhaled from the lung per minute, which is equal to the product of tidal volume and respiratory rate.

Alveolar ventilation: alveolar ventilation refers to the total amount of gas inhaled or exhaled from the alveoli, the total amount of gas inhaled from the lung, and the total amount of gas inhaled from the lung. Compared with lung volume, it can reflect lung ventilation function more comprehensively. Minute ventilation volume: minute lung ventilation volume refers to the total amount of gas inhaled or exhaled from the lung per minute, which is equal to the product of tidal volume and respiratory rate.

Alveolar ventilation: alveolar ventilation refers to the total amount of gas inhaled or exhaled from the alveoli per minute, which is the effective ventilation for direct gas exchange. Compared with lung volume, it can reflect lung ventilation function more comprehensively. Minute ventilation volume: minute lung ventilation volume refers to the total amount of gas inhaled or exhaled from the lung per minute, which is equal to the product of tidal volume and respiratory rate. Alveolar ventilation: alveolar ventilation refers to the total amount of gas inhaled or exhaled from the alveoli per minute. It is the effective ventilation for direct gas exchange. It is the effective ventilation for direct gas exchange.

matters needing attention

Lung ventilation is defined as the amount of gas that is withdrawn from the lung per unit time. It is usually the dynamic breath volume of the lung, which reflects the role of lung ventilation. The lung ventilation volume can be divided into minute ventilation volume, maximum ventilation volume, invalid cavity volume and alveolar ventilation volume. Alveolar ventilation refers to the total amount of gas inhaled or exhaled from the alveoli per minute. It is a useful ventilation for direct gas communication. The gas in and out of the alveoli must pass through the respiratory tract, and the gas in the respiratory tract cannot communicate with the blood, which constitutes an anatomic invalid cavity. The formula is: alveolar ventilation volume per minute = (tidal volume void volume) × Respiratory rate.
