Taking A Measurement; Determining Pulse Signal Quality; Figure 11. Pulse Signal Quality - Nonin CO-Pilot H500 Operator's Manual

System Operation
5. Once display has connected to signal processor, measurement screen
will display. The system is now ready to take a measurement.
NOTE: If the sensor does not turn on, ensure sensor is plugged into the
signal processor. If the sensor still does not turn on, press and hold down the
On/Off, Sleep button on the signal processor.

Taking a Measurement

1. Prepare the system for measurement by following the steps in the
previous section, "Start-up Sequence".
2. Place the sensor on the patient according to sensor instructions.
3. Take measurement.
4. When operation is complete, briefly press the On/Off, Sleep button on
display to end session and turn off the device. Signal processor will turn
off automatically.
During patient measurements the system may reach temperatures of up to 43
degrees Celsius, which is safe for contact with healthy adult skin (no time
restriction).

Determining Pulse Signal Quality

The pulse signal quality can be determined by the color of the pulse waveform
displayed on the display. This pulse waveform changes colors to alert you to
changes in pulse quality that may affect the readings:
• Green Pulse Waveform indicates a good pulse signal.
• Yellow Pulse waveform indicates a marginal pulse signal.
• Red Pulse Waveform indicates an inadequate pulse signal.
Green = Good Yellow = Marginal
