Abstract
An optical circuit detects optical signals reflected from skin tissue at one or more different wavelengths. A processing circuit integrated with the optical circuit or in communication with the optical circuit identifies an insulin release event using at least one optical signal at a first wavelength. A frequency of insulin release events is determined and in response to the frequency of the insulin release events, vascular imaging or a vascular test is delayed or performed.
Claims20
A device, comprising:
- an optical circuit configured to detect photoplethysmography (PPG) signals, wherein a first PPG signal includes a first spectral response around a first wavelength obtained from light reflected from or transmitted through tissue of a user and a second PPG signal includes a second spectral response around a second wavelength obtained from light reflected from or transmitted through the tissue of the user;
- and
- one or more processing circuits configured to:
- identify an insulin release event using the first PPG signal and the second PPG signal, wherein the insulin release event is a pulse of insulin in blood flow of the user;
- and
- determine a frequency of insulin release events.
