1.0 Theory of Operation 1.1 Introduction The Trio portable patient monitor uses a parameter module as the basis for acquiring patient data. The results are transmitted to the main control board to process and display the data and waveforms. CPU board commands and status messages of modules are transmitted via databus. The structure of the entire system is shown in the figure below.
Introduction Theory of Operation As shown in the above figure, the four parameter modules execute real-time monitoring of NIBP, SpO2, ECG/RESP/TEMP and IBP through the use of blood pressure cuffs and patient cables. The patient data is transmitted to the CPU board for display. When required, data may be printed out via the recorder.

Theory of Operation Parameter Circuit Descriptions 1.4 Parameter Circuit Descriptions 1.4.1 ECG The main functions concerning ECG are: • Lead: 3-lead, 5-lead • Lead Method; I, II, III, avR, avL, avF, V, CAL • Floating Input • Right-Leg Drive • Lead-off Detection The ECG circuit is responsible for processing the ECG signals of human body. The circuit consists of following parts: Input Circuit: The ECG electrodes are connected into the circuit through the cable.
Parameter Circuit Descriptions 1.4.3 Theory of Operation NIBP The monitor measures non-invasive blood pressure using the oscillometric method. Detailed measurement procedures follows: 1. Inflate the cuff encircled around the upper arm until the pressure in the cuff blocks the blood flow in the artery of the upper arm. 2. Then deflate the cuff according to the requirement of the algorithm. 3.
Theory of Operation Parameter Circuit Descriptions The sensor measurement wavelengths are nominally 660 nm for the Red LED and 940 nm for the Infrared LED. Maximum optical power output for LED is 4 mW. The amount of light transmitted depends on many factors, most of which are constant. However, one of these factors, arterial blood flow, varies with time because it is pulsating. By measuring the light absorption during a pulsation, it is possible to derive the oxygen saturation of the arterial blood.
