Product overview
The SM-500M is a small monitor with a 7-inch high-brightness colour LCD set vertically, which keeps the footprint narrow. The lead sockets face forward rather than out to the side, so the unit can stand against a wall or on a crowded shelf and still be connected up.
Arrhythmia analysis is provided along with three monitoring modes - diagnostic, monitoring and surgical. SpO₂ measurement is accurate and supports weak-pulse detection. Blood pressure can be taken manually, automatically or in rapid mode, and the data are stored automatically for later retrieval. A high-capacity lithium battery gives a long run time.
It suits an ambulance, a theatre and a general ward, and covers adults, children and infants. Power is AC or battery, so the same unit works at the bedside, in intensive care and while a patient is being moved inside the hospital.
