However, when the equation for estimated energy intake with ad libitum It provides a means of alveolar ventilation and protects the airway and lungs in the 

Figure 17-24 For any given O2 concentration in inspired gas, the relationship between alveolar ventilation and Pao2 is hyperbolic. As the inspired O 2 concentration is increased, the amount that alveolar ventilation must decrease to produce hypoxemia is greatly increased. 15 Jul 2013 There is normally no alveolar dead space, so physiologic dead space equals anatomic dead space. 3. Determined by using the Bohr equation: 4. 11 Feb 2021 The alveolar gas equation is used to calculate alveolar oxygen partial pressure as it is not possible to collect gases directly from the alveoli.

Determining alveolar ventilation 1) The first method determines alveolar ventilation based on tidal volume, pulmonary physiological dead space volume (from Bohr equation) and respiratory rate: VA = (V t –V d) x RR Where V d = V t x (P A CO 2 – P ET CO 2) / P A CO 2 The partial pressure of oxygen in the alveolus ( Pao 2 ) is given by the alveolar gas equation , sometimes also called the ideal alveolar oxygen equation:
