[Design of an anesthesia and micro-environment information management system in mobile operating room].
We have designed a mobile operating room information management system. The system is composed of a client and a server. A client, consisting of a PC, medical equipments, PLC and sensors, provides the acquisition and processing of anesthesia and micro-environment data. ⋯ The client gathers the medical device data by using the C/S mode, and analyzes the obtained HL7 messages through the class library call. The client collects the micro-environment information with PLC, and finishes the data reading with the OPC technology. Experiment results showed that the designed system could manage the patient anesthesia and micro-environment information well, and improve the efficiency of the doctors' works and the digital level of the mobile operating room.

Review[Principles of photoplethysmography and its applications in physiological measurements].
The electro-optic technique of measuring the cardiovascular pulse wave, known as photoplethysmography (PPG), is clinically utilised for noninvasive characterisation of physiological components by dynamic monitoring of tissue optical absorption. Non-invasive PPG technology has been used in a wide range of individual, home or public health monitoring. The application of PPG has become one of the hot topics in the fields of biomedical engineering recently. This paper reviews the optical origins of PPG signal, the feature of PPG technology, the applications of PPG in physiological measurements and its development in the future.
