                   Step 2: Acquire Signal
                   Once you have loaded the patient and sensor information into the Hospital Electronics System and then implanted the sensor, the
                   steps below describe how to set the pulmonary artery (PA) pressure baseline.
                   1.   Place the antenna under the patient’s back, approaching from the side where the sensor was placed. Antenna is not sterile.
                       Sliding the antenna between the sheet and the table works well. Position the center of the antenna under the tip of the patient’s
                       shoulder blade on the side of the torso where the sensor is located.
                   2.   The signal strength (SS) bar indicates the robustness with which the Hospital Electronics System is measuring the implanted
                       sensor. If the signal strength bar is optimal (>70% and a green color, see figure below), go to the next step. If not, go to the
                       section Optimize Signal Strength.

                   Step 3: Set Baseline
                   1.   A pulmonary artery or Swan-Ganz  catheter is used to set the baseline pressure for the sensor. For an accurate sensor
                                              1
                       measurement, it is important to set up the pulmonary artery or Swan-Ganz catheter properly. See Pulmonary Artery Catheter
                       Setup section.
                   2.   Initially, you will observe that the pressure values on the right of the waveform are dashed out. This indicates that the PA
                       pressure baseline has not been set.

                   3.   To Set the PA Pressure Baseline, wait for the screen to fill with a stable pressure waveform and then select the Set Pressure
                       Baseline button.
                   4.   Enter the mean pressure from the pulmonary artery catheter measurement and select the OK button.
