Oleic Acid-Injection in Pigs As a Model for Acute Respiratory
Alveolar Ventilation rate is the volume of air that is exhaled from the alveoli to the outside of the body per minute. It can be calculated based on the tidal volume, dead space and respiratory rate. Formula : Alveolar Ventilation Rate Per Minute = (Tidal Volume - Dead Space) x Respiratory Rate. Alveolar Ventilation rate, measured in ml/min or L/min is a critical physiological variable in Although alveolar ventilation is usually defined as the volume of fresh air entering the alveoli per minute, a similar volume of alveolar air leaving the body per minute is implicit in this definition. The alveolar ventilation is defined as the respiratory rate times (tidal volume – dead space volume).
It can be calculated based on the tidal volume, dead space and respiratory rate. Alveolar Ventilation rate (V' A), measured in ml/min, is the rate of air flow that the gas exchange areas of the lung encounter during normal breathing. The alveolar ventilation rate is a critical physiological variable as it is an important factor in determining the concentrations of oxygen and carbon dioxide in functioning alveoli. Alveolar ventilation and dead space A. Alveolar ventilation (A) is defined as the volume of air entering and leaving the alveoli per minute. Air ventilating the anatomic dead space (VD) (Levitzky Fig 3-7), where no gas exchange occurs, is not included: V T = V D + V A V A = V T - V D Alveolar Ventilation rate, measured in ml/min or L/min is a critical physiological variable in determining the concentrations of oxygen and carbon dioxide in functioning alveoli.

R = removal rate (due to loss by adsorption to sludge particles, Air related diseases are increasing in a faster rate than ever before. Almost half Dirty air damages the alveoli located in our lungs – the most sensitive part of our respiratory system where our blood and air meet.
