■ RESP The PM-7000 measures the RESP based on the impedance principle. While a man is breathing, the action of the breast leads to impedance changes between RL and LL. Change the high-frequency signal passing the RL and LL to amplitude-modulation high-frequency signal (AM high-frequency signal), which is converted to the electric signal after being detected and amplified and then sent to the A/D converter.

Chapter 2 Principles pressure can be obtained. For neonates, pediatric and adults, it is necessary to select the cuffs of a proper size to avoid possible measurement errors. In the NIBP measurement, there is a protection circuit used to protect patient from over-high pressure.
Page 35: Co 2
Chapter 2 Principles Measurement principle: Introduce a catheter, of which the external end is connected to the pressure transducer, into the blood vessel under test, inject the physiological saline. Since the liquid can be transferred by pressure, the pressure inside the blood pressure is transferred by liquid to the pressure transducer, and the dynamic waveform of the pressure inside the blood pressure is obtained in real time.
Page 36 Chapter 2 Principles Send the gas to be measured to a sampling chamber; Use an optical infrared filter, select a specific band of infrared, and transmit it through the gas; Measure the infrared that gets through the gas to obtain the gas concentration. For a given volume, the higher the gas concentration is, the more absorbed infrared is, and the less the infrared that gets through the gas is.
