ArteVu Blood Pressure Accuracy Study

Study Overview
=================
Brief Summary
-----------------
A continuous noninvasive blood pressure monitoring digital fingertip clip device, the ArteVu, will be compared against the reference arterial catheter during operation. The device safety and its blood pressure accuracy will be examined in the study.

Detailed Description
-----------------
ArteVu is a non-invasive and continuous blood pressure monitor. It detects the arterial pressure waveform with a force sensor that detects the arterial pulsation that produces changes in pressure transmitted through the subcutaneous tissue overlying or adjacent to the digital arteries. The data is transmitted to a parameter module to display noninvasive and continuous blood pressure in a hospital setting. The primary objective of this study is to validate ArteVu's blood pressure and heart rate measurement accuracy by comparing its values simultaneously with the corresponding values obtained from an invasive radial arterial line. The secondary objective is to evaluate the effectiveness of utilizing ArteVu for continuous blood pressure measurements. The study population includes 50 patients undergoing surgery who requires general anesthesia and continuous blood pressure measurement with a radial arterial line. Blood pressure values measured from the arterial line will be recorded simultaneously during ArteVu's measurements.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Blood pressure and heart rate measurement accuracy | To validate ArteVu's blood pressure and heart rate measurement accuracy by comparing its values simultaneously with the corresponding values obtained intra-arterially from an invasive radial arterial line, meeting a bias (as measured by overall mean difference) less than 5 mmHg and a standard deviation less than 8 mmHg for systolic and diastolic blood pressure. This accuracy satisfies the limits established for the validation of automatic blood pressure measurement according to the ANSI/AAMI/ISO 81060-2 standard. | around two hours. |
