WebSection Review. Blood flow is the movement of blood through a vessel, tissue, or organ. The slowing or blocking of blood flow is called resistance. Blood pressure is the force that blood exerts upon the walls of the blood vessels or chambers of the heart. WebWe studied the effect of various resistance levels on lung emptying in mechanically ventilated COPD patients. In 18 patients an adjustable resistor was applied. The effect on airways compression was assessed by iso-volume pressure--flow curves (IVPF) and by interrupter measurements.

WebJan 7, 2024 · However, we then have resistance that is of course, using analogy with Ohm's law, inversely proportional to flow; Q (flow) = Pressure gradient /R. Bigger the resistance, smaller the flow. However from that same equation Pressure difference is directly proportional to resistance, meaning bigger the resistance bigger the pressure … WebBlood flow refers to the movement of blood through a vessel, tissue, or organ, and is usually expressed in terms of volume of blood per unit of time.
