WebJan 17, 2024 · Size of the Airway. Resistance in an airway is inversely proportional to the radius of the airway. However the ratio for this relationship is not 1:1. Below is the equation for calculating airway resistance (R). R=8 (Length×Gas Viscosity) (πr4)R=8 (Length×Gas Viscosity) (πr4) The most important part of this formula is radius of the airway ... WebChronic lung disease might increase VD / VT to ≥0.8; in this case, a minute ventilation of ≥25 L·min −1 is required for an effective alveolar ventilation of 5 L·min −1. Measures of wasted ventilation, thus, estimate the effect of V ′ A/Q ′ mismatch on the minute ventilation needed to maintain adequate gas exchange.

WebJan 23, 2024 · Alveolar dead space increases the total physiological dead space, decreasing alveolar ventilation; this results in an increased V/Q ratio and decreases PAO2 for functional alveoli. Hypoxemia results from the reduced PAO2, which may be corrected by oxygen therapy to increase the PAO2 of functioning alveoli. WebDec 14, 2024 · The dead space in an average adult has been reported to be ~150 cc or 2cc/kg ideal body weight. Alveolar dead space: Normally, ventilation and perfusion of respiratory zones (lung units) are nicely matched (normal V/Q ~0.9). Consider a scenario where a small embolus blocks all perfusion to a lung unit.

WebJun 8, 2015 · In summary, increasing PaCO2 causes an increase in minute ventilation. The relationship between PaCO2 is fairly linear in the range of 45-80 mmHg; the rate of minute volume increases by 2-5L/min per every 1mm Hg of CO2 increase.
