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. The alveolar gas equation is only valid if inspired Pco2 = 0, which is a reasonable assumption for room air breathing (Fico2 = 0.0003). Alveolar ventilation is a major determinant of Pao2 because Va determines Paco2, according to the alveolar ventilation equation described earlier. The equation for that relationship is the alveolar gas equation (AGE): This is the simplified version of the AGE and is more than adequate for our needs. If you’re not mathematically minded, that equation reads pretty much as: “The partial pressure of O 2 in the alveoli (P A O 2 ) is whatever fraction of O 2 is being inhaled (F I O 2 ) multiplied by the atmospheric pressure (P B ). Don't forget to do the questions that accompany this video, at http://www.macrophage.co -- it's free and only takes 1 second to sign up!Macrophage is the mos The alveolar gas equation is a formula used to approximate the partial pressure of oxygen in the alveolus (PAO2): PAO 2 = (PB − PH 2 O) FiO 2 − (PaCO 2 ÷ R) where PB is the barometric pressure, PH2O is the water vapor pressure (usually 47 mmHg), FiO2 is the fractional concentration of inspired oxygen, and R is the gas exchange ratio. First, we derive the inverse proportionality relationship between alveolar carbon dioxide partial pressure and alveolar ventilation.

Normal A-a gradient = (Age + 10) / 4 Every 10% rise in the inspired fraction of oxygen increases the partial pressure of available oxygen in the alveoli by approximately 60 to 70 mm Hg. Ventilation is the rate at which gas enters or leaves the lung. The three types of ventilation are minute ventilation, alveolar ventilation, and dead space ventilation. The alveolar ventilation rate changes according to the frequency of breath, tidal volume, and amount of dead space. ventilation (just as alveolar Pco2 is determined by alveolar ventilation). This relationship is expressed by the alveolar gas equation, which incorporates the factors that determine PA 0 , [including partial pressure of 02 in inspired air (P102 )1, PAco2 (which reflects Alveolar Oxygen and Carbon Dioxide Partial Pressures When Va/Q Equals Zero.

It may be initially unclear why the rate of CO 2 diffusion from the pulmonary capillaries into the alveolar space is not a variable in the following equation given our discussion above. Alveolar Gas Equation Calculator This alveolar gas equation calculator determines the alveolar partial pressure of oxygen in the ventilation process to be used in the A-a gradient. There is in depth information about the variables and the formula involved below the form. The equation for that relationship is the alveolar gas equation (AGE): This is the simplified version of the AGE and is more than adequate for our needs. If you’re not mathematically minded, that equation reads pretty much as: “The partial pressure of O 2 in the alveoli (P A O 2 ) is whatever fraction of O 2 is being inhaled (F I O 2 ) multiplied by the atmospheric pressure (P B ).

Alveolar gas equation. An excellent article exploring the history of this equation discusses the original 1946 paper by Fehn, Rahn, and Otis. The modern form of the equation is as follows: Thus, on room air and at sea level, we can assume certain constants. PAO 2 = (0.21 x (760 - 47)) - (PaCO 2 x 1.25) Thus: PAO 2 = (149 - (PaCO 2 x 1.25)

Tidal Volume = 1.0 L Dead Space Volume = 0.15 L Respiratory Rate = 12 breaths / minute Step 2: Substituting the values in the formula Doubling alveolar ventilation cannot double alveolar PO 2 in a person whose alveolar PO 2 is already 104 mm Hg because the highest PAO 2 one can achieve (breathing air at sea level) is the inspired PO 2 of about 149 mm Hg (Levitzky Fig 3-10 bottom). The alveolar PO2 can be calculated by using the alveolar air equation: The alveolar gas equation is the method for calculating partial pressure of alveolar oxygen (P A O 2). The equation is used in assessing if the lungs are properly transferring oxygen into the blood. The alveolar air equation is not widely used in clinical medicine, probably because of the complicated appearance of its classic forms. The alveolar gas equation allows us to predict a parallel rise in Pa o 2 with supplemental O 2 use, assuming ventilation and metabolic rates are unchanged.
