SYSTEM FOR MEASURING VITAL SIGNS USING AN OPTICAL MODULE FEATURING A GREEN LIGHT SOURCE
First Claim
1. A system for measuring vital signs from a patient, comprising:
- a first sensor comprising a first electrode that measures a first electrical signal from the patient;
a second sensor comprising a second electrode that measures a second electrical signal from the patient;
a third sensor comprising an optical system comprising a light source configured to emit green radiation between 510-590 nm and a photodetector configured to measure green radiation emitted from the light source after it irradiates the patient to generate an optical signal; and
a controller comprising a system configured to;
i) receive and process the first and second electrical signals to generate an electrical waveform;
ii) receive and process the optical signal to generate an optical waveform; and
iii) calculate a time difference between a first feature on the electrical waveform and a second feature on the optical waveform to determine a blood pressure for the patient.
