8 TONOPORT VI 2001589-312 Revision B
The inflation measurement method is a novel method
based on the "Inflation Measurement Technology (IMT)"
developed by PAR Medizintechnik. With this innovative
technique, the cuff is inflated to a pressure just above the
expected systolic value. Once the systolic value is
determined, the cuff can immediately and quickly be
deflated. The measurement typically takes only approx.
20 seconds.
If disturbances occur during measurements with the
inflation measurement method, which may be due to
motion artifacts, for example, TONOPORT VI will
automatically switch to the deflation measurement
method and complete the blood pressure measurement.

during a measurement using the inflation
measurement method: systolic pressure at
125 mmHg, diastolic pressure at 83 mmHg
With both methods, a pressure transducer measures the
cuff pressure as well as the superimposed pressure
pulsations. During blood pressure measurements the cuff
must be at heart level. If this is not ensured, the
hydrostatic pressure of the liquid column in the blood
vessels will lead to incorrect results.
When the patient is sitting or standing during
measurements, the cuff is automatically at the correct
level.
1.2 Functional Description
The TONOPORT VI monitor accommodates the blood
pressure measuring system and a microprocessor for
system control and data processing.
A second microprocessor with a second pressure
transducer and a second valve are provided for control of
the technical safety.
The monitor is powered by two AA size batteries (either
rechargeable NiMH batteries or alkaline batteries).
