    Figure 12.  Setting PA Pressure Baseline.

                    5.   Wait for the screen to re-fill with a stable pressure waveform and then confirm that the sensor mean pressure matches the
                       catheter PA mean pressure within +/- 1mm Hg. Repeat the PA Baseline step as necessary to achieve a good match between
                       measurements.

                    6.   Confirm that the height of the sensor pressure signal (i.e., pulse pressure (systolic – diastolic)) is within +/- 25% of the catheter
                       pulse pressure. See Pulmonary Artery Catheter Setup section. Set the PA Pressure Baseline again, if necessary.
                    7.   Setting the cardiac output baseline is an optional step.
                    8.   To set the cardiac output (CO) baseline, you will need a reference value for cardiac output. This can be either thermodilution or
                       modified Fick.
                    9.   Select the button Set CO Baseline. The Hospital Electronics System will indicate that the baseline data is being collected and
                       will prompt for the reference cardiac output once finished.
