Abstract:
Objective To design and develop a portable multi -parameter life sign monitor. Methods Electrocardiogram (ECG). blood pressure(BP), breath frequency (BF), heart rate (HR) and body temperature (BT) in real time were recorded with a single-chip microprocessor 8Xc196Mc and a high-resolution (640×200) graphic liquid crystal display (LCD) through sign al detecting and processing techniques. Results This system cou ld display the ECG wave, and other parameters in real time dynamically. It could also provide a 24 hours trend graph for each parameter measured and exchange th e data through the serial communication interface (RS232) with the PC. C onclusion This portable monitoring system is capable of performing cont inuous monitoring and also has the capability to resist environmental interferen ce through the added design, so it can be used widely.
