Radar vital signs monitor is a device which measures rapidly and accurately the heart and respiration rates without making any physical contact with the patient. The device works on the principle of Doppler Effect. It is an extremely sensitive motion detection system which is capable of detecting the small movements of the chest in response to the cardiac and respiratory functioning. Due to the fact that it doesn’t need any physical contact with the patient it finds applications in numerous fields. This paper explores the various aspects of the RVSM technology including its working and special features. The numerous applications of this technology are also discussed. That sudden chill of the stethoscope as it touches our body may soon be a distant memory. The new Radar Vital Signs Technology introduced by Eugene .F. Greneker Offers us an innovative method of getting the vital signs of a patient without making any physical contact with him. This technology also offers several other applications too
