ABSTRACT

Objective: Non-invasive continuous blood pressure (NICBP) monitoring is an alternative to the standard non-invasive sporadic blood pressure monitoring. It allows measuring mean arterial blood pressure (MBP), systolic blood pressure (SBP), and diastolic blood pressure (DBP). Its results seem to have a good correlation with the values of invasive continuous blood pressure. The aim of our study was to assess the feasibility of using this device in a pre-hospital setting.

Methods: The measurements taken for adult patients who were treated by Advanced Life Support teams equipped with NICBP (Nexfin™) device from one to 20 August 2015 were analysed prospectively The main outcome parameter was the number of faulty BP measurements obtained by Nexfin™ on one arm compared to the BP cuff on the other arm.

Results: Nine patients were included. The mean age was 53 [40-61]. The number of faulty measurements was 1 for Nexfin™ and 10 for the cuff. There was a good correlation and concordance between the measurements recorded by Nexfin™ and cuff for SBP (77% vs 89%), DBP (70% vs 85%), and MBP (64% vs 82%) respectively.

Conclusion: Although its big size and the low battery life, NICBP monitoring seems to be a valuable option considering its good correlation with the conventional method.
