Pressure exposure and catheter impingement affect the recorded pressure in the Manoscan 360 ™ system

Conclusions and InferencesIn addition to the known effects of temperature, both sustained pressure exposure and catheter impingement significantly affect the recorded pressure and the magnitude of the PD observed at the end of the recording. These effects can be substantial enough to result in erroneous manometric diagnoses.

The accuracy of pressure measurements by Manoscan system is affected by development of pressure drift (PD) throughout the recording. Application of sustained pressure significantly increased PD, and catheter impingement produced remarkable increases in the recorded pressure as well as PD. In addition to the known effects of temperature, both sustained pressure exposure and catheter impingement significantly affect the recorded pressure and PD observed at the end of the recording. These effects can be substantial enough to result in erroneous manometric diagnoses.
