Flow pressure/resistance

WebFeb 6, 2024 · Blood pressure decreases with decreased cardiac output, peripheral vascular resistance, volume of blood, viscosity of blood and elasticity of vessel walls. Cardiac Output Cardiac output is the volume of blood flow from the heart through the ventricles, and is usually measured in litres per minute (L/min). WebAirway resistance is the opposition to flow caused by the forces of friction. It is defined as the ratio of driving pressure to the rate of air flow. Resistance to flow in the airways depends on whether the flow is laminar or turbulent, on the dimensions of the airway, and on the viscosity of the gas. For laminar flow, resistance is quite low.
