AC CC Module 2
Question | Answer |
---|---|
Poiseuille's Law | Flow=Pressure/Resistance |
Left ventricular systole occurs... | slightly before right ventricular systole |
Preload | The degree of ventricular stretch befor the next contraction. |
How is preload measured? | By measuring the ventricular end pressures. |
Frank-Starling Law | When ventricular fibers are at maximal stretch, maximal cardiac output results. |
The goal of many therapeutic interventions in critical care? | Optimizing preload or ventricular filling. |
Afterload | The amount of resistance the ventricles must overcome to deliver the stroke volume into the receiving vasculature. |
