3. Functions
PLETH: The monitor can display PLETH waveform
Intelligent parameter monitoring screen: The monitor automatically selects the parameter measurements to display according to the probes connected to the monitor.
Audio and visual alarm: The speaker sounds the alarm and the parameter's measurement will become in red to flash on the screen. Also the same when sensor-off.
Prompting: Icons of battery capacity, pulse sound switch and alarm sound switch.
Power saving: The monitor will automatic shut down to save power. The time is settable.
Trend: Storage/Review trend data up to 3888 groups, data save time being set freely
Data storage: The saved data will never be lost even if the monitor is powered off.
Communication: Transmitting the patient's trend to a PC for display, observation, saving and printing.
