Abstract
The invention provides a system for measuring vital signs from a patient that includes: 1) a first sensor including a first electrode that measures a first electrical signal from the patient; 2) a second sensor including a second electrode that measures a second electrical signal from the patient; and 3) a third sensor including an optical system with a light source configured to emit green radiation and a photodetector configured to measure the green radiation emitted from the light source, after it irradiates the patient, to generate an optical signal; and 4) a controller that receives and processes the first and second optical and electrical signals and the electrical waveform to determine the patient's vital signs.
