The invention provides a monitor for measuring blood pressure and other vital signs from a patient without using a cuff. The invention provides a hand-held device for measuring vital signs (e.g. blood pressure) from a patient that features: i) a housing that encloses a first sensor, that includes a first electrode and a first optical system configured to generate a first optical signal; ii) a second sensor that includes a second electrode and a second optical system configured to generate a second optical signal; iii) an amplifier system, in electrical contact with the first and second electrodes, configured to processes electrical signals from the first and second electrodes to generate an electrical waveform; and iv) a microprocessor, in electrical communication with the amplifier system, first optical system, and second optical system, the microprocessor configured to process the electrical waveform and first and second optical signals with an algorithm to determine at least one of the patient's vital signs.

The invention features a monitoring device that measures a patient's vital signs (e.g.). The device features a first sensor configured to attach to a first portion of the patient's body that includes: i)a first electrode configured to generate a first electrical signal fron the first portion of the patient's body; ii)a first light-emitting component; and iii)a first photodetector configured to receive radiation from the first portion of the patient's body after the radiation is emitted by the first light-emiting component and in response generate a first optical waveform. The device also features a second sensor that includes essentially the same components. An amplifier system, in electrical contact with the first and second electrodes, receives first and second electrical signal from the two sensors to generate an electrical waveform. A processor, in electrical contact with the amplifier system, receives the electrical waveform, the first optical waveform, and the second optical waveform. The processor runs computer code that processes the input waveforms with an algorithm to determine at least one of the patient's vital signs.
