NIBP
Propaq Encore Reference Guide 57 Welch Allyn
NIBP measurements are affected by normal physiological pressure variations from reading
to reading. Normal respiration may affect pressure by as much as 10 to 20 mmHg. Patient’s
emotional state, body position, and cuff fit may also adversely affect NIBP measurements. In
some individuals, the act of taking blood pressure readings may alter the blood pressure.
Successive readings on the same patient may vary for the above reasons.
The static accuracy of the Propaq’s internal manometer can be verified by a qualified
biomedical engineer using a mercury column manometer (refer to the Propaq Encore Service
Manual). The accuracy of the Propaq’s determination of systolic, diastolic, and mean
pressures in a clinical setting can only be assessed by careful statistical analysis of controlled
clinical trials of representative patient populations.
Improve NIBP Accuracy with Smartcuf™
NIBP measurements can be adversely affected by many factor such as cardiac arrhythmias,
sudden changes in blood pressure, body motions such as convulsions or shivering, bumping
the cuff, vibration, vehicle motion, or weak pulses.
The patented Smartcuf software filtering technology greatly increases NIBP measurement
accuracy in the presence of motion artifact or diminished pulses. Smartcuf synchronizes the
NIBP reading with the R-wave of the patient’s ECG to eliminate noise created by external
stimuli such as patient motion or vibration. The monitor must perform ECG monitoring
while using Smartcuf.
To enable the Smartcuf filter:
• Connect the ECG leads to the patient and perform ECG monitoring during NIBP.
• From the Main Menu, press
NIBP
to display the NIBP Menu and set Smartcuf to ON.
