Patient preparation for invasive blood pressure monitoring
The following tips provide optimal invasive blood
pressure monitoring results but must never replace
hospital-approved practices or manufacturer’s
recommendations.
– When preparing the patient, make sure there
are no air bubbles in the sensor or the stopcock.
– For maximum signal strength, choose the
shortest possible length of pressure tubing.
Shorter pressure tubing reduces signal
attenuation but is more susceptible to motion
artifacts. Pressure tubing with higher pressure
limits signal dampening.
– Position the transducer so that it is level with the
appropriate anatomical reference point for each
monitored pressure.
Invasive blood pressure display
On the Cockpit, the invasive blood pressure display
consists of:
– Invasive blood pressure parameter field
– Invasive blood pressure waveform
Invasive blood pressure parameter field
Parameter fields report parameter values and
indicate the alarm status of parameters. Parameter
fields can also report technical conditions such as
disconnected sensors, and so on. For detailed
information regarding the content of parameter
fields for each parameter, see the chapter
"Troubleshooting" on page 509.
The content of the invasive blood pressure
parameter fields depends on whether the parameter
is pulsatile or non-pulsatile. Parameter fields for
pulsatile blood pressures (ART, LV, PA, RV, GP1,
GP2, GP3, GP4) display systolic, diastolic, and
mean pressure values. Parameter fields for non-
pulsatile pressures (LA, RA, CVP, ICP) display only
the mean pressure value.
If the M540 detects a static pressure, the algorithm
computes only the mean pressure. A static
pressure condition occurs when the maximum and
minimum values of a pulsatile blood pressure
signal differ by less than 3 mmHg (0.4 kPa).
NOTE
If air bubbles appear in the tubing system, flush
the system with the infusion solution again. Air
bubbles may lead to wrong pressure
measurement values.
NOTE
The following diagram shows a typical parameter
field layout. This layout may change when
additional parameters are put on display. For
more information, see "Parameter fields"
on page 62.
