V. Connecting the Monitoring Kit to the Patient
The IBP transducer must not be mounted to the patient, or patient burn may result.
8‐8 Monitoring Invasive Blood Pressure
Place transducer in the position (horizontal plane) it will maintain
during pressure measurement.
Place the catheter tip at the right atrial (mid‐axillary) level.
Zero the transducer. Zero the transducer. Press the Zero All key.
(Alternatively, use Zero Set in the respective P1 or P2 menu to zero
a specific channel connected to the transducer; see page 8‐24).
Zeroing All Pressure Channels (or Zeroing Pressure Channel for a
single channel if Zero Set was used) will be displayed and zeroing
will begin; where, upon completion, Done will be displayed to
If the transducer will not zero and an error condition occurs, verify
that the transducer is being used as described in the manufacturer's
instructions. Press Retry to attempt zeroing again. If the transducer
still does not zero, try another transducer and/or cable; and, if
condition persists, contact technical support or authorized service
Repeat this zeroing, leveling, and calibration procedure for each additional monitoring line
Transducers are pre‐calibrated to industry standards.
Remove yellow non‐vented cover at patient connector. A continuous flush of approximately
3 ml per hour should be observed in the drip chamber. Drop rate should be approximately 1
drop per minute. For each additional monitoring line, the continuous flush will increase by 3
ml/hr (i.e., 6 ml/hr for two lines).
For a systemic arterial blood pressure line, activate the fast flush mechanism of the
continuous flush device, while allowing arterial cannula to backflow during attachment. For
pulmonary artery catheters, the monitoring kit should be attached to the catheter and the
