Chapter 2 Principles 1) Input circuit: The input circuit protects the ECG input level, and filters the ECG signals and external interference. The ECG electrode is connected to the input circuit through the cable. 2) Buffer amplifying circuit: This circuit ensures extremely high input impedance and low output resistance for ECG.
Chapter 2 Principles of the patient; 2) Manual/Auto/Continuous mode: The manual measurement is also called single measurement; in this mode, only one measurement is done after being started. In the auto measurement mode, the measurement can be done once within the selected period, with the interval being 1, 2, 3, 4, 5, 10, 15, 30, 60, 90, 120, 180, 240 or 480 minutes.
Chapter 2 Principles algorithm. 2.4.7 CO CO measurement principle: The thermal dilution method is widely used in the clinical CO monitoring. Introduce a floating catheter into the pulmonary artery through the right atrium, and inject the physiological saline into the right atrium through the catheter whose front end is connected to the temperature transducer. When the cold liquid mixes with the blood, there will be a change of temperature.
Chapter 2 Principles gases, multiple infrared filters are required in the AG module. The oxygen does not absorb the infrared within the above-mentioned wave band. Therefore, the oxygen is measured based on its paramagnetism. Inside the transducer of the O2 module, there are two crystal balls full of nitrogen. They are suspended in the symmetrical magnetic field, and designed to point to the strongest outgoing part of the magnetic field. Outside the balls is the paramagnetic oxygen.
