Comparing noninvasive blood pressure monitoring technologies: the challenge of between-arm differences

The authors examine the performance of a finger-cuff system for continuous noninvasive blood pressure monitoring in comparison to traditional oscillometric methods and invasive arterial measurements. They highlight that while the finger-cuff system meets ISO criteria for mean arterial and diastolic pressures, it does not for systolic pressure, and the observed discrepancies may be influenced by physiological differences between arms. Ultimately, the editorial argues that the study supports the use of finger-cuff technology for mean arterial pressure monitoring but does not conclusively establish its superiority over oscillometric methods.
