Why the study?

Current monitoring of physiological signs requires contact devices that can be inconvenient and cause discomfort, prompting interest in contactless remote photoplethysmography technology.

Does Vastmindz's camera-based remote photoplethysmography technology accurately measure vital signs compared to standard medical devices in a diverse clinical population?

Population

Subjects in a wide range of age, height, weight, and baseline vital signs

Comparison

Vastmindz rPPG technology vs regulated medical devices

Key result

Vastmindz's camera-based remote monitoring technology estimated heart rate, respiratory rate, and oxygen saturation with a mean error of ±3 units, and blood pressure within ±10 mmHg compared to standard medical devices.

Structured PICO

Does Vastmindz's camera-based remote photoplethysmography technology accurately measure vital signs compared to standard medical devices in a diverse clinical population?

P
Population
463 adults aged 18 to 83 years with various skin colors and medical statuses underwent a 60-second facial scan to evaluate the accuracy of a camera-based vital sign monitoring solution against standard medical devices.
I
Intervention
Vastmindz's remote photoplethysmography (rPPG) technology (contactless monitoring using a regular camera via 3.0 SDK) for a 60-second scan.
C
Comparator
Gold standard vital signs monitors (Massimo mightiest for HR and RR; OMRON/CIRCA MICRO LIFE/NIDEK multi-parameter monitor and pulse oximeters).
O
Outcome
Accuracy of heart rate (HR), respiratory rate (RR), blood pressure (BP), and oxygen saturation (SpO2) measurements compared to reference devices.surrogate

Main Result

Effect estimate: HR: -1.19; RR: -2.11; SpO2: 0.3; SBP: -5.27; DBP: -3.95 (Mean Errors)

Camera-based remote photoplethysmography can estimate heart rate, respiratory rate, and oxygen saturation with a mean error of ±3 units and blood pressure within ±10 mmHg compared to standard medical devices.

Limitations

  • High standard deviation of error for blood pressure readings, particularly struggling with extreme values (SBP > 150 mmHg and DBP > 90 mmHg).
  • Limited sample size for individuals with SpO2 below 90%.
  • Potential for motion artifacts during image acquisition affecting heart rate estimation in extreme cases.
  • Limited samples with SpO2 below 90%
  • Struggles with extreme blood pressure values (SBP >150 mmHg and DBP >90 mmHg)
  • Outliers in HR estimation possibly related to motion artifacts or wrong ground truth measurement

Talukdar et al. (2022) conducted a cross-sectional in General health and wellness (n=463). Vastmindz camera-based remote photoplethysmography (rPPG) technology vs. Regulated medical devices (gold standard vital signs monitors) was evaluated on Mean error of heart rate, respiratory rate, oxygen saturation, and blood pressure estimation (HR: -1.19; RR: -2.11; SpO2: 0.3; SBP: -5.27; DBP: -3.95 (Mean Errors)). Vastmindz's camera-based remote monitoring technology estimated heart rate, respiratory rate, and oxygen saturation with a mean error of ±3 units, and blood pressure within ±10 mmHg compared to standard medical devices.
