Tanabe N, Todoran T, Zenk G, Aono J, WAGNER Jr W, Presson Jr R
J Appl Physiol (1985)
. 2000 Oct;
89(5):1943-8.
PMID: 11053347
Perfusion of the pulmonary acinus has been shown to be generally homogeneous, but there is a significant component that is heterogeneous. To investigate the contribution of the alveolar septal capillary...

Jaryszak E, Baumgartner Jr W, Peterson A, Presson Jr R, Glenny R, WAGNER Jr W
J Appl Physiol (1985)
. 2000 Aug;
89(3):1233-8.
PMID: 10956374
To determine how rapidly pulmonary capillaries recruit after sudden changes in blood flow, we used an isolated canine lung lobe perfused by two pumps running in parallel. When one pump...

WAGNER Jr W, Todoran T, Tanabe N, Wagner T, Tanner J, Glenny R, et al.
J Appl Physiol (1985)
. 1999 Mar;
86(3):825-31.
PMID: 10066692
Pulmonary capillary perfusion was analyzed from videomicroscopic recordings to determine flow switching characteristics among capillary segments in isolated, blood-perfused canine lungs. Within each alveolus, the rapid switching pattern was repetitive...

WAGNER Jr W, Todoran T, Tanabe N, Wagner T, Glenny R, Presson Jr R
Chest
. 1998 Jul;
114(1 Suppl):16S-17S.
PMID: 9676604

Tanabe N, Todoran T, Zenk G, Bunton B, WAGNER Jr W, Presson Jr R
J Appl Physiol (1985)
. 1998 Apr;
84(3):933-8.
PMID: 9480954
There is little information on the distribution of acinar perfusion because it is difficult to resolve blood flow within such small regions. We hypothesized that the known heterogeneity of arteriolar...

Presson Jr R, Audi S, Hanger C, Zenk G, Sidner R, Linehan J, et al.
J Appl Physiol (1985)
. 1998 Feb;
84(1):303-10.
PMID: 9451650
Previously, the pressure changes after arterial and venous occlusion have been used to characterize the longitudinal distribution of pulmonary vascular resistance with respect to vascular compliance using compartmental models. However,...

Presson Jr R, Todoran T, De Witt B, McMurtry I, WAGNER Jr W
J Appl Physiol (1985)
. 1997 Aug;
83(2):543-9.
PMID: 9262451
Increasing pulmonary blood flow and the associated rise in capillary perfusion pressure cause capillary recruitment. The resulting increase in capillary volume limits the decrease in capillary transit time. We hypothesize...

Hanger C, Presson Jr R, Okada O, Janke S, Watkins J, WAGNER Jr W, et al.
J Appl Physiol (1985)
. 1997 Apr;
82(4):1283-9.
PMID: 9104866
Individual pulmonary capillaries are not steadily perfused. By using in vivo microscopy, it can readily be demonstrated that perfusion continually switches between capillary segments and between portions of the network...

Short A, Montoya M, Gebb S, Presson Jr R, WAGNER Jr W, Capen R
J Appl Physiol (1985)
. 1996 May;
80(5):1568-73.
PMID: 8727541
In vivo microscopic observations of pulmonary capillaries are limited to subpleural networks that are less dense than interior networks. In addition to the density difference, subpleural and interior capillary diameters...

Godbey P, Graham J, Presson Jr R, WAGNER Jr W, LLOYD Jr T
J Appl Physiol (1985)
. 1995 Oct;
79(4):1142-7.
PMID: 8567555
To investigate the effect of capillary pressure and alveolar distension on capillary recruitment, we used video-microscopy to quantify capillary recruitment in individual subpleural alveolar walls. Canine lobes were perfused with...
