Non-invasive blood pressure (NIBP)
290 Instructions for use – Infinity Acute Care System – Monitoring Applications VG6.n
Overview of non-invasive blood pressure monitoring
The M540 uses the oscillometric method to acquire
and process non-invasive blood pressure (NIBP)
signals and sends the results to the Cockpit for
display. Blood pressure measurements are
determined by the oscillometric method and are
equivalent to those obtained by intra-arterial
methods, within the limits prescribed by the
Association for Advancement of Medical
Instrumentation, Electronic Automated
Sphygmomanometers.
The M540 inflates and then deflates a blood
pressure cuff wrapped around the patient’s arm or
leg. A hose connects the cuff to the monitor which
determines the systolic, diastolic and mean
pressures for adult, pediatric and neonatal patients.
To protect the patient from excessive inflation limits,
the blood pressure cuff automatically deflates
when:
– A measurement exceeds 2 minutes in adult and
pediatric mode
– A measurement exceeds 90 seconds in
neonatal mode
Refer to the instructions for use Infinity Acute Care
System – Infinity M540 for a detailed description of
the M540 non-invasive blood pressure functions.
The non-invasive blood pressure monitoring
functions are configurable in the parameter-specific
setup page (see page 300).
Before performing any monitoring functions, refer
to the section "For your safety and that of your
patients" on page 13. Parameter-specific error
messages are listed on page 534.
Supported parameters
– NIBP S – systolic non-invasive blood pressure
– NIBP D – diastolic non-invasive blood pressure
– NIBP M – mean non-invasive blood pressure
NOTE
The non-invasive blood pressure functionality
should be calibrated every two years by technical-
ly qualified personnel as described in the Service
manual.
