Abstract

Monitoring respiratory activity provides important information about patient’s well-being. There are many respiratory activity monitoring techniques introduced so far. This paper presents a portable respiratory monitor using Respiratory Inductive Plethysmography (RIP) technology. RIP sensor’s characteristics are also studied. Experimental results have shown that RIP sensor’s sensitivity and linearity can be improved by designing the RIP sensor properly. In addition, the monitor’s accuracy in term of respiratory rate measurement is verified by experiment on 10 subjects. Experimental results have shown that our monitor can measure respiratory rate with error ±1 bpm. Furthermore, it can transfer data to PC (via Bluetooth) where chest and abdomen movement efforts are plotted. These plots are useful for diagnosing and monitoring several respiratory disorders.
