Load normalisation1

  • Better oxygen delivery to restored muscle triggers signals that harm brain and lung circulation

    Where this hypothesis actsMuscle graft arteries in an aged host, with contraction and systemic physiological conditions held constant

    What is proposedReduce arterial resistance to increase graft oxygen delivery

    With whatNot stated in the record

    HowLocal arterial dilation while holding contraction, arterial CO2, systemic arterial oxygenation, and systemic pressure constant

    Possible resultExpected increased afferent and sympathetic activity, followed by reduced cerebral flow and raised filling pressure
