Signal Processing
and AI Technologies

Vitalism.ai extracts health measurements from a video stream of exposed skin on the surface of a human face. The video stream is analyzed with advanced AI and deep learning algorithms, including computer vision technology and signal processing. No identifiable features, such as eyes, are needed.

In approximately one minute, users can measure blood pressure, heart rate, heart rate variability,oxygen saturation, breathing rate,respiratory rate.

Vitalism.ai’s technology runs on the device, enabling users to perform scans without connection to the internet. Vitalism SDK has absolutely no access to end-user’s health data.

The human heart consists of four chambers: the left atrium, the left ventricle, the right atrium, and the right ventricle. The atriums act as receiving chambers, contracting to push blood into the ventricles. The ventricles serve as pumps, transporting oxygenated blood to the body's tissues and deoxygenated blood and carbon dioxide back to the heart. Heartbeats are composed of phases of contraction and relaxation

Heart rate (HR) is the number of heart beats per minute. Heart Rate Variability (HRV) is the fluctuation in the time intervals between adjacent heartbeats (RR intervals – RRi) [26]. HRV is generated by heart-brain interactions and autonomic nervous system processes and reflects regulation of autonomic balance, blood pressure, blood vessel diameter, gas exchange, gut, and heart.

The main function of the respiratory system is gas exchange, where oxygen is transferred from the environment into the bloodstream and carbon dioxide is expelled. When inhaling, air passes to the lungs and gas exchange occurs when oxygen diffuses into the lung capillaries in exchange with carbon dioxide. Exhalation starts after gas exchange and the air containing carbon dioxide returns to the external ambient through the nose or mouth. The respiratory system also has secondary functions like filtering, warming, and humidifying the inhaled air.
