Example recording from a vessel that was able to eject for every contraction during a Pout ramp. Horizontal dotted line corresponds to contractions that resulted in opening of the output valve without peak systolic PL equaling or exceeding Pout. At the end of the ramp, Pin and Pout were elevated simultaneously to 10 cmH2O to check the calibration of the pipette used to measure PL.
