Distribution of Ventilation-Perfusion Ratios in Pneumonectomized Dogs

Respiration, 2009
In this paper, the distribution of ventilation (VA) and of pulmonary perfusion (0), 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.

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.

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

The distribution of ventilation‐perfusion ratios in the lungs of a dysmature foal

Equine Veterinary Journal, 1990
Summary The distribution of ventilation‐perfusion (V A /Q) ratios, before and after 100 per cent oxygen, was studied in an induced‐premature foal at 4 h and again at eleven days of age, using the multiple inert gas elimination technique.

[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%.
