the transducer. Unfortunately, manometers can add significant errors
themselves, because of the difficulty in interpreting the liquid level in the
column. This affects the calibration of and subsequent determination of
the liquid height.
The critical nature of invasive blood pressure measurement requires a
properly calibrated monitoring system capable of linear operation over a
wide range of pressure levels. Pressures at the catheter tip should be
accurately transmitted through the connective tubing and stopcocks to
the transducer-sensing diaphragm. In a properly operating system,
distention of the diaphragm will generate an output voltage proportional
to the applied pressure. Occasionally, one or more of the elements
involved in this process will malfunction causing inaccurate indications
of blood pressure on the monitor. Very often these errors can be
attributed to a transducer with a nonlinear response or shifted
sensitivity.
