A wearable cuffless blood pressure monitoring system: real-time measurement using force sensing and waveform analysis
Authors' conclusion
This study represents the first clinical validation of a tactile force-sensing cuffless system against intra-arterial reference measurements, demonstrating its feasibility for real-time, non-invasive blood pressure monitoring during anesthesia.
Study context
- Population
- Patients in the operating room
- Participants
- 46 patients
- Comparison
- Cuffless device vs Intra-arterial catheter
- Outcome
- Error between paired measurements (systolic and diastolic BP) vs intra-arterial catheter
Methodological detailsclinical validation, intra-arterial reference, Data analysis also considered the IEEE 1708 standard
- Clinical validation
- Intra-arterial reference
