18-4
Systolic, diastolic, and mean pressure values are displayed for arterial, pulmonary
artery, umbilical artery, umbilical vein and generic pressures. Only the mean value
is displayed for other pressure types. Refer to the Display Detail on page 18-5 for
a sample arterial pressure and intracranial pressure display on the bedside
monitor.
Setting Up Pressure Monitoring
Connect the cable end of either a reusable or disposable transducer to the
pressure connector located on the front of the module using a Spacelabs Medical
pressure cable.
When setting up an invasive pressure system, take all measures to maintain
system sterility and to prevent the introduction of air into the system. Air bubbles
are the most common cause of inaccurate pressure readings. The transducer,
stopcocks, connectors and tubing must be completely free of air to ensure
maximum performance.
Zeroing the Pressure Transducer
Before you can begin monitoring you must zero the system. Zeroing has two
purposes: 1) to establish atmospheric pressure as zero, and 2) to compensate for
the hydrostatic effect of fluid in the catheter-tubing system.
WARNING:
• Systolic and diastolic pressures displayed numerically for
patients being treated with an Intra-Aortic Balloon Pump
(IABP) therapy may not be accurate. Display the waveform
with scales to verify or determine pressures for these
patients.
!
• With the Module Configuration Manager feature, you can define
your own default settings for such characteristics as alarm limits
and display configuration. Refer to the Module Configuration
Manager on page 7-5 for further details.
!
• Refer to the catheter, tubing, or transducer manufacturer’s
instructions or your hospital’s protocol for specific instructions
on removing air from the system.
• Invasive pressure systems specified by Spacelabs Medical are
compatible with high-frequency electrosurgical and defibrillation
equipment. No special precautions are required.
!
• If after you have followed the instructions to zero the pressure
transducer and a ZERO REJECTED message appears, you
may have a transducer problem. Follow the transducer
manufacturer's directions to correct this problem before you
continue.
To zero the pressure transducer:
1 Touch the desired pressure
parameter key.
2 Open stopcock to air/close to
patient (at phlebostatic axis).
3 Touch ZERO.
4 Close stopcock to air/open to
patient.
5 Begin monitoring after the
pressure values appear.
