Journal ArticleDOI
Mechanism of exercise-induced hypoxemia in horses
Peter D. Wagner,J. R. Gillespie,G. L. Landgren,M. R. Fedde,B. W. Jones,Richard M. DeBowes,R. L. Pieschl,Howard H. Erickson +7 more
TL;DR: Most of the exercise-induced hypoxemia is thus the result of diffusion limitation with a smaller contribution from VA/Q inequality and essentially none from shunting.
Journal ArticleDOI
Pulmonary blood flow distribution in standing horses is not dominated by gravity
Michael P. Hlastala,Susan L. Bernard,Howard H. Erickson,M. R. Fedde,Earl M. Gaughan,Rose M. McMurphy,M. J. Emery,Nayak L. Polissar,Robb W. Glenny +8 more
TL;DR: In lungs of resting unanesthetized horses, animals with a large lung height, there is no consistent vertical gradient to pulmonary blood flow and there is a considerable degree of perfusion heterogeneity, indicating that gravity alone does not play the major role in determining blood flow distribution.
Journal ArticleDOI
Relationship of structure and function of the avian respiratory system to disease susceptibility
TL;DR: The predominant site of respiratory infections in the caudal air sacs, compared to other parts of the respiratory system, can be explained by the gas flow pathway and the mechanisms present in the parabronchi for particle removal.
Journal ArticleDOI
Quantification of exercise‐induced pulmonary haemorrhage with bronchoalveolar lavage
TL;DR: The results with BAL used as the diagnostic tool, suggest that all strenuously exercised horses may exhibit EIPH; the amount of haemorrhage appears to be associated with the magnitude of the high pulmonary arterial pressure.
Journal ArticleDOI
Minimal redistribution of pulmonary blood flow with exercise in racehorses.
Susan L. Bernard,Robb W. Glenny,Howard H. Erickson,M. R. Fedde,Nayak L. Polissar,Randall J. Basaraba,Michael P. Hlastala +6 more
TL;DR: This study determined the spatial distribution of pulmonary blood flow at rest and during increasing levels of exercise in Thoroughbred racehorses using 15-microns fluorescent microspheres and found that thirty percent of the variation in pulmonaryBlood flow seen in horses over rest and exercising states is due to redistribution.
