2.4.6 IBP
The IBP module can monitor the arterial pressure, central venous pressure and pulmonary arterial
pressure.
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. Thus, the arterial pressure, central venous pressure and
pulmonary arterial pressure are obtained based on specific algorithm.
2.4.7 CO2
The CO2 module works based on the infrared spectrum absorption principle. The sidestream
CO2 module is composed of the circuit board, inbuilt sidestream infrared light transducer,
deflation pump and control. When used, this module requires the external water trap, drying pipe
and sampling tube. In the sidestream mode, the deflation rate can be set to 100ml/min, 150ml/min
or 200ml/min according to the patient situation. When the CO2 measurement is not being
conducted, the sidestream deflation pump and the infrared source are expected to be shut down,
thus to extend the service life and reduce the power consumption of the module.
