PRE-CONSULTATION VITAL SIGNS TRIAGE • 60 FPS rPPG

Medical vitals in 40 seconds.
Before your teleconsultation begins.

Because telehealth lacks physical presence in a medical facility, doctors typically consult without baseline vitals. VitaPulse allows patients to capture certified resting heart rate, blood pressure trends, SpO2, and respiration directly from their camera prior to their scheduled appointment — giving clinicians complete hemodynamic insight before greeting the patient.

No physical presence in a medical facility?
Doctors review objective vital signs before the scheduled call.

In traditional in-person doctor visits, a nurse always records your vitals in triage before the physician enters. In telehealth, doctors are forced to consult blind without any physical baseline. VitaPulse bridges this diagnostic gap with an autonomous 40-second scan in the virtual waiting room.

STAGE 01 5 MINS PRE-APPOINTMENT

Virtual Waiting Room Check-In

When the patient clicks their video visit confirmation link, the virtual waiting room prompts a 40-second camera check. No blood pressure cuffs or wearables to pair — simply look at the screen.

STAGE 02 40 SECONDS OPTICAL SCAN

Autonomous Hemodynamic Extraction

Our rPPG engine captures micro-capillary light absorption at 540nm. In 40 seconds, it calculates certified Resting HR, Systolic/Diastolic BP trends, Respiratory rate, and SpO2 with r = 0.98 accuracy.

STAGE 03 DOCTOR JOINS CALL

Clinician Reviews Prior to Greeting

The physician joins the video call with the patient's verified vitals already mapped on their screen. Doctors can immediately detect hypertensive spikes, tachycardia, or hypoxia from minute one.

82%
Clinical Telemedicine Reality: In published clinical studies, over 82% of virtual physicians report hesitation prescribing medication or diagnosing without objective physical vitals. Capturing vitals before the call restores in-person clinical confidence.

How Contactless rPPG Extracts Blood Pulsation

With every cardiac contraction, blood rushes through the microvascular facial bed. Oxygenated hemoglobin absorbs green spectrum light (~540nm) differently from ambient skin reflection. VitaPulse quantifies these invisible sub-pixel chromatic shifts at 60 frames per second.

The 4-Stage Photoplethysmography Pipeline

From raw consumer webcam pixels to certified clinical hemodynamic waveforms.

01

Dense Facial Mesh & ROI Segmentation

Detects 468 3D facial landmarks to isolate optimal micro-capillary vascular zones across the zygomatic arch (cheeks) and frontal region (forehead), eliminating occlusion from facial hair or glasses.

02

Sub-Pixel Chromatic Decomposition (POS & CHROM)

Applies Plane-Orthogonal-to-Skin (POS) and Chrominance (CHROM) algorithms to cancel ambient light fluctuations and head motion artifacts while extracting the underlying pulse wave.

03

Spatial-Temporal Convolutional Deep Learning

Our deep neural model reconstructs clean arterial pulse waves with micro-second fidelity, resolving dicrotic notch morphology and inter-beat intervals (IBI).

04

Hemodynamic & Autonomic Feature Derivation

Translates pulse waveforms into accurate measurements for Heart Rate (BPM), Heart Rate Variability (SDNN/RMSSD), Blood Pressure trends via Pulse Transit Time, and Respiratory Rate.
