The primary finding of this study was that PBF redistribution occurred from rest to exercise, both with and without furosemide. However, there was less blood flow to the dorsal portion of the lung during exercise postfurosemide compared with prefurosemide. Furosemide did alter the resting perfusion distribution by increasing the flow to the ventral regions of the lung; however, that increase in flow was abated with exercise. Other findings included 1) unchanged gas exchange and cardiac output during rest and exercise after vs. before furosemide, 2) a decrease in pulmonary arterial pressure after furosemide, 3) an increase in the slope of the relationship of PBF vs. vertical height up the lung during exercise, both with and without furosemide, and 4) a decrease in blood flow to the dorsal region of the lung at rest after furosemide. Pulmonary perfusion variability within the lung may be a function of the anatomy of the pulmonary vessels that results in a predominantly fixed spatial pattern of flow distribution.<\/jats:p>","DOI":"10.1152\/jappl.1999.86.6.2034","type":"journal-article","created":{"date-parts":[[2017,12,22]],"date-time":"2017-12-22T13:55:22Z","timestamp":1513950922000},"page":"2034-2043","source":"Crossref","is-referenced-by-count":16,"title":["Effect of furosemide on pulmonary blood flow distribution in resting and exercising horses"],"prefix":"10.1152","volume":"86","author":[{"given":"Howard H.","family":"Erickson","sequence":"first","affiliation":[{"name":"Department of Anatomy and Physiology,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan L.","family":"Bernard","sequence":"additional","affiliation":[{"name":"Department of Medicine and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robb W.","family":"Glenny","sequence":"additional","affiliation":[{"name":"Department of Medicine and"},{"name":"Department of Physiology and Biophysics, University of Washington, Seattle, Washington 98195-6522; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.
