  • Blood pressure differences when lying down, standing up, and . . .
    Blood pressure lying down verses standing has the same variations as lying down vs sitting Moving from a standing to a supine (lying down) position could result in different readings Blood
  • Blood pressure and blood flow variation during postural . . .
    With normal auto-regulation, blood flow velocity precedes changes in peripheral blood pressure, reflecting local adjustments to intracranial pressure Finally, to obtain a blood flow velocity during standing that is equivalent to that during sitting, the resistance reaches a set point that is higher during standing than during sitting
