2.3.11 Multi-Parameter board
The Multi-parameter board is integrated with multiple parameters, such as ECG, RESP,
SPO2, IBP, NIBP, TEMP, etc. Refer to the following introductions for details.
 The Multi-parameter board employs a high-speed DSP, making digital filtering,
arrhythmia analysis and ST analysis faster and more effective.
 The Multi-parameter board supports 3-, 5- and 12-lead ECG monitoring, arrhythmia
and ST analysis, and has a good capability to resist electrosurgical unit interference
and 50/60Hz frequency.
 The Multi-parameter board supports 2-channel measurement of temperature.
 The Multi-parameter board measures the respiration rate of patients using the
impedance method, and can monitor the respiration rate with two ECG leads.
 The Multi-parameter board is integrated with Mindray SpO2 circuit. If a monitor is
configured with an OEM SpO2 module, the function of Mindray SpO2 is shielded.
 The Multi-parameter board supports 2-channel measurement of IBP.

2.3.12 C.O. and IBP module
The C.O. and IBP module supports 2-channel measurement of IBP and C.O.. The module
consists of an amplification circuit, AD converter, CPU circuit and power isolation circuit.
The signals amplified by the amplification circuit are converted to digital signals through
the AD converter, which are then collected by CPU and sent to the main unit via an
isolation coupler after being processed.
2.3.13 CO2 module
 There are three types of CO2 modules: Mindray CO2, Microstream CO2 and
Mainstream CO2.
 The Mindray CO2 module measures the concentration of CO2 using the NDIR
technology. It zeroes periodically to ensure accurate measurements for a long period of
time. Appropriate compensations can be made based on the operating environment,
thus preventing measurements from being influenced by interfered gases.
 The world-class Microstream CO2 module ensures measurements are not affected by
other gases and can be obtained accurately without any gas compensation. Additionally,
the module has a very low sample flow rate, reducing its maximum effects on the
patient and the environment.
 The world-class Mainstream CO2 module is compact and convenient for use. It adopts
the power isolation technology of Mindray and thus meets the CF requirements of
power isolation.
