1.1 General Information
M3 Vital Signs Monitor (hereinafter called monitor) monitors parameters such as SpO2(Areterial
oxygen saturation for pulse oximetry)and NIBP(Non-invasive blood pressure), and is adaptable
to adult, pediatric, and neonatal in ahospital environment and duringpatient transport both inside
and outside hospitals. The user can select different parameters configuration accordingto
different requirements in clinic, hospital or operatingroom.
The monitor centralizes the function of parameter measurement modules, display,record and
output to compose acompact, portable device. Its built-in replaceable batteryprovides
