This is an operator's manual for the N-200 pulse oximeter.
The Nellcor N-200 Pulse Oximeter is a medical device intended as an adjunct in patient assessment to measure oxygen saturation (SpO2) and pulse rate. It operates by using NELLCOR sensors placed on extremities, with measurements affected by factors such as motion, perfusion levels, and ambient light. The device features automatic self-tests, configurable alarm limits, and various operating modes including standard oximetry and ECG synchronization via the C-LOCK feature.
| Saturation Range | 0–100% |
|---|---|
| Pulse Rate Range | 20–250 bpm |
| Operating Temperature | 41–107.6°F (5–42°C) |
| Battery Life | 90 minutes typical |
| Dimensions (with powerbase) | 6.5 high x 10 wide x 10 in deep |
The saturation accuracy for adults without motion is ±2 digits within the range of 70 to 100%.
No, the device must not be used during magnetic resonance image (MRI) scanning due to potential burns and reduced accuracy.
The device can operate accurately at altitudes up to 10,000 ft (0–3,048 m).
