6. Open the transducer’s stopcock to air to zero the transducer and remove stopcock cap. Select
the P1 area. Select ZERO from the menu. The message P1 ZEROED appears when zeroing is
complete and the pressure values are displayed as zeros.
7. Close the stopcock to air. The patient’s pressure waveform should be displayed. A scale is
automatically selected to display the pressure. Confirm that pressure amplitude correlates with
the digital readout.
Note: If you place a cap on an open port before you close the port to air, an error message may
appear. You will be required to zero the transducer again.
If pressure alarms are desired, set the alarms after you obtain a satisfactory waveform. Error or
alarm messages appear in the message area at the bottom of the screen. For more information, see
"Alarms" on page 3-21.
IP Scale Options
The IP monitor can display pressures from -30 to 300 mmHg. After zeroing the transducer
pressure, the monitor automatically selects one of the following scales based on the patient’s
measured pressure:
• -30 to 30 mmHg
• 0 to 60 mmHg
• 0 to 120 mmHg
• 0 to 150 mmHg
• 0 to 180 mmHg
• 0 to 300 mmHg
You can also manually select one of these scales or autoscale to readjust the waveform within the
channel.
To change the scale:
1. Use the SPEED DIAL to outline and select the P1 area. The P1 menu appears.
2. From the menu, select SCALE and then choose a scale from the list.
