Comparison of Continuous Non-invasive Arterial Pressure (CNAP) With Invasive Arterial Pressure Monitoring

Blood Pressure Clinical Trial

Official title: Accuracy of the CNAP™ Monitor (Continuous Non-invasive Arterial Pressure) Versus Invasive Radial Arterial Monitoring in Surgical Patients

Status Completed

Clinical Trial Summary

The purpose of this study was to compare the Continuous Non-invasive Arterial Pressure (CNAP) monitor with the gold standard of invasive arterial pressure monitoring during:

1. induction and maintenance of general anaesthesia

2. intensive care unit treatment of postoperative patients with an ASA 3 or 4 status

Clinical Trial Description

The CNAP monitor continuously measures blood pressure using a finger cuff. It showed a good agreement to invasive blood pressure measurements during anaesthesia induction and maintenance during surgery. In critical ill patients cardiac arrhythmia is probably a confounding factor affecting accuracy and interchangeability of CNAP. As systolic arterial CNAP pressure in comparison to mean pressure shows no statistical interchangeability with invasive measurements, mean pressure should be considered when making therapy decisions.

A problem is the missing standard criterion for comparison of continuously devices with invasive pressure. ;
