Cardiac output dependent on
Note:
Shows how changes in right atrial pressure affects cardiac output
Shows how changes in cardiac output affects right atrial pressure
Note:
Interaction of cardiac function curve and vascular function curve shows
--> the equilibrium cardiac output at a particular level of right atrial pressure (or central venous pressure)
In normal person, at equilibrium,
In most cases (in normal persons)
When HR is between 100-200 [BL8:p217]
Changes in heart rate
--> Changes in preload, afterload, and contractility
--> Cardiac output is not changed significantly
