Clinical Validation of a Soft Wireless Continuous Blood Pressure Sensor During Surgery

Abstract: We test a new wireless soft capacitance sensor (CAP) based on applanation tonometry at the radial and dorsalis pedis arteries against the gold standard, invasive arterial line (A-Line), for continuous beat to beat blood pressure (BP) measurements in the Operating Room during surgical procedures under anesthesia in 17 subjects with the mean age and body mass index (BMI) of 57. 35 ± 18.72 years and 27.36 ± 4.20 kg/m2, respectively. We have identified several parameters to monitor in order to compare how well the… Show more

“…All the traits above enabled us to create a sensor that can take accurate and longer beat‐to‐beat BP measurements without requiring recalibration than previously reported. [ 50–52 ] There were several limitations of this initial study. We demonstrated feasibility only on a relatively small sample size of healthy subjects; while we demonstrated sustained measurements for 10 min without recalibration, this was done only under stationary conditions (where the subjects did not move) because the Caretaker does not tolerate movement and requires recalibration upon a change in HR above 20 beats.…”
