Measurement of respiratory variations of blood flow (V_peak) is physiologically sound, but blood flow sampling through the aortic valve (AV-V_peak) is not always feasible.

We report the overall feasibility of AV- and SS-V_peak, and calculated their interchangeability, the mean bias with limits of agreement (LoA) and percentage error (PE).
