Capillary recruitment
WebWe have also observed pulmonary capillary recruitment in normal humans during exercise (unpublished data). Recruitment is a normal physiological process, and it is impaired in many types of PH. As we move forward in our understanding of exercise PH and its physiology, precise definitions and semantics will be critical.

WebPrior studies of functional pulmonary capillary surface area (FCSA) in animal models, and our recent studies in exercising humans, demonstrate that both phenomena occur, but at different phases of increasing flow [13–15]. At low to moderate flows, capillary recruitment is predominant and, at higher flows close to WebAug 1, 2001 · Percentage capillary recruitment was assessed by dividing the increase in capillary density during postocclusive reactive hyperemia by the capillary density in the resting state. (Note that this procedure yields 2 different estimates of percentage capillary recruitment, depending on whether capillary density in the resting state is defined by ...
WebRationale: Alveolar capillary dysplasia with misalignment of pulmonary veins (ACDMPV) is linked to heterozygous mutations in the FOXF1 (Forkhead Box F1) gene, a key transcriptional regulator of pulmonary vascular development. There are no effective treatments for ACDMPV other than lung transplant, and new pharmacological agents … The term «vascular recruitment» or «capillary recruitment» usually refers to the increase in the number perfused capillaries in skeletal muscle in response to a stimulus. The most important stimulus in humans is regular exercise. Vascular recruitment in skeletal muscle is thought to enhance the capillary … See more Vascular recruitment is the increase in the number of perfused capillaries in response to a stimulus. I.e., the more you exercise regularly, the more oxygen can reach your muscles. Vascular … See more Vascular recruitment in the brain is thought to lead to new capillaries and increase the cerebral blood flow. See more Vascular recruitment in the lung (i.e., in the pulmonary microcirculation) may be noteworthy to healthcare professionals in emergency medicine, … See more The existence of vascular recruitment in response to a stimulus has been disputed by some researchers. However, most researchers accept that vascular recruitment exists. See more
