Document Summary
Pulmonary & alveolar ventilation: pulmonary ventilation (or minute volume) = tidal volume x frequency, since not all the volume of gas entering the lung participates in gas exchange, another important factor to consider is alveolar ventilation. In a normal (70 kg) subject deadspace volume is approx. In a normal subject anatomic dead space is similar to total dead space enter nonfunctional alveoli volume entering those areas would contribute to total dead space. In certain diseases, inhaled air may: volume of total dead space can be calculated using bohr equation, this calculation is based on the assumption hat all expired co2 comes from alveolar gas and not from dead space. Paco2 pco2 of alveolar gas (or paco2 because it is the same value as arterial co2) 6000 ml (200-150) x 30 = 1500 ml. 6000 ml (600-150) x 10 = 4500 ml. Typical values in healthy adult: shows some typical values of flow and volumes to.
