PanopticAI Vital Signs
The PanopticAl Vital Signs device is intended for noninvasive spot measurement of pulse rate when the subject is still. It is software for assessing facial video stream captured from a specified smartphone or tablet camera.
The PanopticAl Vital Signs device is intended for use by healthcare professionals. The device is only intended to be used in healthy subjects.
The PanopticAl Vital Signs device is indicated for use on humans 18 to 60 years of age who do not require critical care or continuous monitoring.
The PanopticAl Vital Signs device is not intended to be the sole method to assess a subject's physical health condition. The pulse rate measurements it provides should complement, not replace, professional medical care and/or medication.
PanopticAl Vital Signs is a medical software device that uses remote photoplethysmography (rPPG) to measure a person's pulse rate. The app utilizes the surrounding light as the light source and works by capturing and measuring the subtle color changes on the skin caused by light absorption and reflection by the blood vessels beneath the skin. The app uses the front camera of an iPhone or iPad to capture videos of the subject. Then, the algorithm in the app detects and tracks the subject's face to capture the subtle light changes reflected in the changes in RGB pixel values. This information is sent to PanopticAl's cloud server for further processing to calculate the pulse rate. The pulse rate value is then returned to the PanopticAl Vital Signs app, and the result is displayed on the app.
Here's a breakdown of the acceptance criteria and study details for the PanopticAI Vital Signs device, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance

2. Sample Size Used for the Test Set and Data Provenance
- Sample Size (Clinical Validation Study): N=107
- Data Provenance: The document does not explicitly state the country of origin. It describes participants based on gender, age, BMI, facial shape, history of hypertension, race/ethnicity (Asian, Black, Hispanic, White), and Fitzpatrick Skin Type Scale. The study appears to be prospective since it's a clinical validation study aiming to assess agreement between the device and a "standard pulse rate measurement by a clinician."
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
The document mentions "standard pulse rate measurement by a clinician" as the ground truth. It does not specify the number of clinicians or their specific qualifications (e.g., years of experience).
4. Adjudication Method for the Test Set
The document does not describe an adjudication method for establishing ground truth. The ground truth was based on "standard pulse rate measurement by a clinician."
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No. The document describes a clinical validation study comparing the device's performance to a clinician's standard measurement. It does not mention an MRMC study or the effect size of human readers improving with AI assistance. The device is a standalone measurement tool.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
Yes, a standalone study was performed. The clinical validation study directly assesses the PanopticAI Vital Signs app's accuracy against a clinical standard, demonstrating its performance without human interpretation of its outputs beyond what is displayed by the app itself. The device is intended for "non-invasive spot measurement of pulse rate," implying a direct output from the algorithm.
7. Type of Ground Truth Used
The ground truth used was expert consensus / clinical measurement from a "clinician" performing "standard pulse rate measurement."
8. Sample Size for the Training Set
The document does not provide information regarding the sample size for the training set. It focuses solely on the clinical validation (test) set.
9. How the Ground Truth for the Training Set Was Established
Since the training set sample size is not provided, how its ground truth was established is also not described in this document.
