Parametric estimation of ventilation-perfusion ratio distributions

Journal of Applied Physiology, 1983
We present a model and rigorous statistical approach for recovery of ventilation-perfusion ratio (V/Q) distribution parameters from multiple inert gas elimination data. We model the lung as a parallel combination of shunt, dead space, and one to three log-normal distributions of gas exchange units.

Distribution of Ventilation-Perfusion Ratios in Pneumonectomized Dogs

Respiration, 1980
In this paper, the distribution of ventilation (VA) and of pulmonary perfusion (Q), gas exchanges, and the single breath CO diffusing capacity are measured in 8 dogs before and after left pneumonectomy. During surgery 4 dogs, in which the left pulmonary artery is clamped, and 4 other dogs in which the left mainstem bronchus is clamped, are studied.

Estimation of distributions of ventilation/perfusion ratios

Annals of Biomedical Engineering, 1981
For many years physiologists have sought to estimate the distribution of ventilation/perfusion ratios ( $$\dot V_A /\dot Q$$ ) in the lung. While many different procedures have been described, most share two features that limit their usefulness. First, while the

[Ventilation-perfusion ratios and pulmonary shunt].

Biulleten' eksperimental'noi biologii i meditsiny, 1980
A group of 63 healthy subjects aged from 17 to 29 years were studied in a sitting posture. The following indices of pulmonary ventilation were revealed: Vd, phys/VT-30 +/- +/- 0.6%, AaDO2-10 +/- 0.9 mm Hg, aADCO2 (PA, CO2 = = Pet, CO2)-5.0 +/- 0.4 mm Hg, Qva/QT (air)-2.3 +/- 0.3% Qs/QT (O2)-1.8 +/- 0.2%.
