The study NCT04379986 aims at evaluating the performance of the Senbiosys technology in monitoring blood pressure (BP) values for elderly patients: 25 patients undergoing coronary angiography, aged 68.92 ± 6.41 years, and 10 patients in the intensive care unit (ICU), aged 71.90 ± 8.56 years. The technology is based on pulse wave analysis (PWA) of low-power photoplethysmography (PPG) from the SBF2003 ring. The PPG recordings are processed by the PPG-based blood pressure monitoring (PPG-BPM) algorithm 1 to generate systolic BP (SBP) and diastolic BP (DBP) estimates. For the SBP, the mean difference ± standard deviation between the reference arterial line and the PPG-BPM values is 0 ± 5.06 mmHg for the patients undergoing coronary angiography and 0 ± 7.46 mmHg for the patients in the ICU. For the DBP, the mean difference ± standard deviation between the reference arterial line and the PPG-BPM values is 0 ± 1.85 mmHg for the patients undergoing coronary angiography and 0 ± 4.17 mmHg for the patients in the ICU. The results show that the accuracy of our algorithm is within the 5 ± 8 mmHg ISO/ANSI/AAMI protocol requirement. |
