  Pulse and Oxygen Saturation Module

FEATURES:

• Small, flexible and easy setup, with high reliable and accurate readings.
• Provide quick, accurate measurement of Spo2 and pulse rate.
• Adopt advanced digital signal processing technology enhances performance during low perfusion and motion interference.
• By comparing invasive clinical test of precision withCO-OXIMETERto ensure clinical monitoring precision.
• Available for Adult, pediatric, and neonatal patients.
• 3.3 volt Single-Supply, low-power design.
• Plethysmographic waveform and pulse amplitude blip bar displays.
• Easy serial ports connection, which is ease of integration.
• Ensure a precise measurement during poor perfusion (see Simulator P10.075).
• Ensure a precise measurement under the defined 13 motion conditions of Simulator.
