Capillary recruitment

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 See more WebWe have also observed pulmonary capillary recruitment in normal humans during exercise (unpublished data).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. Footnotes
