Introduction It’s a non - invasive medical test NASA developed a technology for calculating cardiac output For Arteries, blood flow in any area. Result will be recorded in a Graph. we use 2 pair of Surface Electrodes. Technique It is measured by constant current method. Blood is a good conductor of electricity, the amount of blood in a given body segment. Pulsatile blood volume by heart . Variation in the electrical impedance thus gives adequate information about the blood circulation. Voltage signal developed along the current. The amplitude of the signal sensed is directly proportional to the electrical impedance of the body segment. Amplification & detection of this signal gives instantaneous electrical impedance Z of the body segment.

2. Introduction
• It’s a non - invasive medical test
• NASA developed a technology for calculating cardiac output
• For Arteries, blood flow in any area.
• Result will be recorded in a Graph.
• we use 2 pair of Surface Electrodes.

3. Technique
• It is measured by constant current method.
• Blood is a good conductor of electricity, the amount of blood in a
given body segment.
• Pulsatile blood volume by heart .
• Variation in the electrical impedance thus gives adequate information
about the blood circulation.

4. Technique
• Voltage signal developed along the current.
• The amplitude of the signal sensed is directly proportional to the
electrical impedance of the body segment.
• Amplification & detection of this signal gives instantaneous electrical
impedance Z of the body segment.
