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 signal detecting and processing techniques. Results This system could 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 the data through the serial communication interface (RS232) with the PC. Conclusion This portable monitoring system is capable of performing continuous monitoring and also has the capability to resist environmental interference through the added design, so it can be used widely.
