Non-Contact Vital States Identification of Trapped Living Bodies Using Ultra-Wideband Bio-Radar

Identifying the vital states of trapped survivors during post-disaster rescue missions can result in improved strategies and provide injury pre-diagnosis information. The most effective method is use bio-radar based non-contact measurements. Presently, techniques focus on detecting locating. Herein, a to identify with an ultra-wideband proposed, while simulating condition Beagle dogs. This investigation revealed three stages under condition: normal, transitioning, agonal stages. Upon entering transitioning stage, heartrates were apparently high, respiratory rates increased sharply. temperatures dropped rapidly once passing this stage. In particular, waveforms from frequently change normal sine like curve “M” within accurate beginning ending stage are defined by newly proposed indicator relative occurrence frequency. Pathological observations indicated that fragmentation lamellar bodies type II alveolar cells caused insufficiency lung surfactant, further resulted curves. pioneering work realizes identification only using bio-radar, thereby enables infer health conditions, life expectancy, appropriate subsequent treatment victims condition. Therefore, it has potential promote welfare human victims.
