Product overview
The SM-500S is the portable member of the 500 series. The screen is a 12-inch high-brightness TFT at 800 x 600, the interface is available in fourteen languages, and the unit runs on mains or battery, so it moves between a ward bed, intensive care and a theatre without being switched off.
It monitors the ECG waveform, heart rate, non-invasive blood pressure, SpO₂, respiratory rate and temperature; invasive blood pressure and end-tidal CO₂ are optional. Defibrillation and electrosurgery interference are rejected, weak-perfusion SpO₂ monitoring is supported, and ST segment and arrhythmia analysis are provided. Non-invasive blood pressure uses dual over-pressure protection.
Trend data are held for 720 hours, waveforms for 2 hours, 1000 blood pressure readings and 200 alarm events. Alarms are graded three ways with adjustable volume, drug concentration and titration calculations are built in, and the monitor supports nurse call and wired, wireless or mixed networking. A touch screen and a built-in recorder are optional.
