The Multi-Parameter Patient Monitor uses a high resolution LCD screen to display essential parameters such as SpO2, NIBP, and CO2. With the new T-SESP mode, respiration can be measured through a nasal tube, rather than through the more common ECG method, making respiration more simple to measure. The patient monitor accurately measures SpO2 in a low perfusion situation, and the maximum 8 waveform display can also measure drug concentration calculation, ST-segment detection, pace-maker and arrhythmia analysis.
