1.3.7 Invasive Pressure Acquisition
1. Plug the pressure transducer into the PRESSURE TRANSDUCER connector (28) or (29) on
the side panel.
2.
To establish a monitoring site introduce an arterial pressure catheter into the patient’s
artery in accordance with standard hospital procedures. “Best practice,” as determined
by the medical community, should be observed.
NOTE: The arterial pressure catheter should not be used on a limb
that is being utilized for any other medical procedure. For
example, an I.V. catheter or an SpO
2
sensor.
3. Connect catheter line with flushing device to the pressure transducer.
4. Zero pressure transducer as follows:
Initially, a “TRANSDUCER NOT ZEROED” message is displayed in the parameter
window, indicating the need to zero the transducer.
a. Open transducer vent to atmosphere.
b.
Press ZERO (8) or (9) and hold for a minimum of one second.
After one second has elapsed, an audible click will sound, and the automatic zero
process is complete. The pressure display should indicate zeros.
NOTE: If the transducer offset should exceed 120 mmHg, it will not
be possible to automatically zero the transducer. Pressure
values will be —- and an “UNABLE TO ZERO” message
replaces the “TRANSDUCER NOT ZEROED” message.
5. Close the pressure transducer vent from atmosphere and check that the pressure
waveform is displayed on the screen.
6. Select the desired pressure scale in the IBP Menu. The choices are: 37.5, 75, 150, or
300 mmHg.
7. Flush arterial line at regular intervals per standard hospital procedure.
NOTE: Pressure transducers are protected against the effects of
defibrillation and electrocautery.
1.3.8 Sequence for Establishing SpO
2
To obtain SpO
2
measurements, SpO
2
Heart Rate, and the plethysmographic waveform from
the Passport Monitor (including units equipped with Nellcor® SpO
2
).
1.
Select the appropriate sensor for the patient.
Guidelines for the selection of Datascope sensors are provided in the Table 1-7 on
page 1-38.
2. Plug the patient cable into the SpO
2
Connector (25) on the left side panel.
3. Apply sensor and connect to cable.
NOTE: Do not place the sensor on an extremity with an invasive
catheter or blood pressure cuff in place.
