System for measuring vital signs using an optical module featuring a green light source

A system for measuring vital signs from a patient, comprising:

• a first electrode comprised by a first adhesive patch and configured to measure a first electrical signal from the patient;
• a second electrode comprised by a second adhesive patch and configured to measure a second electrical signal from the patient;
• a third sensor comprised by an adhesive patch and 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 reflected off 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.
