Product overview
The SM-500D is a fifteen-inch monitor for intensive care and for the operating theatre. The screen is a high-brightness TFT at 1024 x 768, the interface is available in fourteen languages, and the unit runs on mains or on its internal battery, so a theatre list is not interrupted by moving the patient.
As standard it monitors the ECG waveform, heart rate, non-invasive blood pressure, SpO₂, respiratory rate and temperature. Invasive blood pressure, end-tidal CO₂, depth of anaesthesia and anaesthetic gas monitoring are optional, which lets one platform cover a ward bed and a theatre bay.
Rejection of defibrillation and electrosurgery interference is designed in, weak-perfusion SpO₂ monitoring is supported, and ST segment and arrhythmia analysis are provided. Non-invasive blood pressure measurement 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 - sound, light and voice - with adjustable volume, and drug concentration and titration table calculations are built in. The monitor supports a nurse call system and wired, wireless or mixed networking.
