Cardiac Output Measurement
Cardiac output; Adolf Eugen Fick (1829-1901) in 1870, was the first to measure cardiac output; assumes oxygen consumption is a function of rate of blood flow and rate of oxygen pick pick up by RBC’s.
The Futility of Orthostatic Measurements
Assess for orthostatic symptoms, not BP changes.
