A device for measurement of cardiac output including an elongate body and a plurality of electrical components, including at least an energy producing element, such as a heating coil, and a temperature sensing element, such as a thermistor. The elongate body includes a plurality of electrical lead wires configured to transmit electric current to the electrical components and at least one insulation layer configured to electrically insulate the plurality of lead wires from one another. Preferably, a cross-sectional size of the elongate body is generally equal to a combination of the cross-sectional size of the plurality of lead wires and a cross-sectional size of the at least one insulation layer. In a preferred method of use, the device is introduced into the radial artery of a patient.
