Brief Summary

Self-measured, non-invasive accurate blood pressure monitoring continues to be a major challenge for automated vital sign measurement systems. The general notion is that with reliable, self-administered BP monitoring in the clinic and at home, health care providers will be able to diagnose hypertension among individuals at an early stage, including high risk patients in the community, and more quickly assess if prescribed treatment plans are working. The imPulse™ Tor System detects 1) audible and inaudible low-frequency, low-amplitude sounds generated by the body, including arterial pulse waveforms, and 2) ECG-derived heart cycle identification, which can be combined with the vibroacoustic data to estimate blood pressure. The imPulse™ Tor has undergone preliminary testing. In this pilot study, we collect data from health care workers for algorithm training and validation study to achieve medical grade device AAMI/ISO and IEEE standards compliance.

Outcome Measures

Primary Outcomes (1)

  • imPulse™ Tor System Blood Pressure Prediction

    Following AI/ML algorithm training and validation the difference between predicted systolic, diastolic, and mean arterial pressure predictions of the imPulse™ Tor and gold-standard measurement of an electronic blood pressure cuff will be less than 2.5 mmHg in at least 90% of the measurements, less than 5 mmHg in at least 92.5% of the measurements and less than 10 mmHg in at least 95% of the measurements.

  • imPulse™ Tor Oxygen Saturation Prediction
