Zeroing the Transducer

To ensure that the Propaq MD unit measures pressure accurately, you must zero the transducer
before each use. If you change or disconnect a transducer, you must zero the new transducer
before use. If you move a transducer to a different monitor, you must zero the transducer again,
even if you have already done so on another unit. In addition to the procedure below, follow the
transducer manufacturer's Directions for Use and your organization's established clinical
protocol.
Follow these steps when zeroing a transducer:
1. Place the transducer at the same height as the patient's left atrium.
2. Close the transducer stopcock to the patient.
3. Open the transducer's venting stopcock to atmospheric air.
Allow the transducer a few seconds to settle.
