Evaluation of a Camera-Based Monitoring Solution Against Regulated Medical Devices to Measure Heart Rate, Respiratory...

Area of Science:

• Biomedical Engineering
• Health Informatics
• Medical Technology

Background:

• Regular monitoring of physiological signs like heart rate, blood pressure, and oxygen saturation is crucial for early detection of conditions, especially cardiovascular diseases (CVDs).
• The COVID-19 pandemic has accelerated interest in remote patient monitoring solutions.
• Current contact-based devices for physiological monitoring can cause user inconvenience and discomfort.

Purpose of the Study:

• To evaluate the accuracy and clinical feasibility of Vastmindz's remote photoplethysmography (rPPG) technology for contactless vital signs monitoring.
• To compare the performance of Vastmindz's rPPG technology against established medical devices in a diverse clinical setting.

Main Methods:

• Utilized a regular camera to capture blood volume pulse signals via contactless remote photoplethysmography (rPPG).
• Conducted a clinical evaluation involving a diverse cohort of subjects with varying age, height, weight, and baseline vital signs.
• Compared rPPG-derived vital signs against measurements from medical-grade contact devices.

Main Results:

• Vastmindz's contactless rPPG technology demonstrated accurate estimation of heart rate, respiratory rate, and oxygen saturation with a mean error of ±3 units.
• The technology achieved an acceptable mean error of ±10 mmHg for systolic and diastolic blood pressure.
• The study confirmed the technology's ability to provide physiological information comparable to contact-based devices.

Conclusions:

• Vastmindz's rPPG technology meets its initial performance hypotheses in a clinical environment.
• The contactless vital signs monitoring system is suitable for users seeking to track general health and wellness.
• This technology presents a viable, convenient alternative to traditional physiological monitoring methods.
