1. Introduction
The Pulox PO-200A Solo Pulse Oximeter is a non-invasive device designed for spot-checking oxygen saturation (SpO2) and pulse rate (PRbpm) in adults and pediatric patients. It is suitable for use at home, in medical facilities, or during sports activities. This manual provides essential information for the safe and effective operation of your device.
2. Safety Information
- Read all instructions carefully before using the device.
- This device is intended for non-invasive spot-checking only. It is not intended for continuous monitoring.
- Do not use the device in an MRI or CT environment.
- Keep the device out of reach of children.
- Consult a physician for medical interpretation of results. Self-diagnosis and self-treatment based on measurement results can be dangerous.
- Do not use the device on the same finger for more than 5 minutes to avoid discomfort or swelling.
- Avoid using the device in direct sunlight or strong artificial light, as this may affect measurement accuracy.

6. Operating Instructions
Follow these steps to take a measurement:
- Open the clamp of the oximeter.
- Insert one finger (preferably the index finger) into the rubber opening of the oximeter, ensuring the fingernail is facing upwards towards the display.
- Release the clamp. The device should fit snugly but comfortably on your finger.
- Press the power button once to turn on the oximeter.
- Keep your hand still and avoid movement during the measurement. The readings for SpO2 and pulse rate will appear on the display within a few seconds.
- The device will automatically power off after approximately 8 seconds of inactivity or if the finger is removed.

7. Alarm Function
The Pulox PO-200A Solo features an adjustable alarm function for SpO2 and pulse rate:
- With the device turned on, press and hold the power button for approximately 2 seconds to enter the settings menu.
- Short presses of the power button will cycle through menu options (e.g., Pulse Prompt, SpO2 Prompt, High/Low limits).
- To change a setting, press and hold the power button when the desired option is highlighted. Short presses will adjust the value, and a long press will confirm the selection and move to the next setting or exit.
- You can set individual high and low limits for both SpO2 and pulse rate. An audible alarm will sound if your readings fall outside these predefined limits.

8. Display Information
The clear LCD screen provides comprehensive information:
- SpO2 (%): Percentage of oxygen saturation in the blood.
- PRbpm: Pulse rate in beats per minute.
- Pulse Bar Graph: Visual representation of pulse strength.
- Pulse Waveform: Graphical display of the pulse.
- Battery Indicator: Shows remaining battery life.
The display automatically rotates 90 degrees depending on the device's orientation, ensuring easy readability from various angles.

9. Maintenance and Care
Proper maintenance ensures the longevity and accuracy of your device:
- Cleaning: Clean the surface of the oximeter with a soft cloth dampened with medical alcohol (70% ethanol or isopropanol). Do not immerse the device in water or other cleaning solutions.
- Storage: Store the device in a cool, dry place, away from direct sunlight, high temperatures, and moisture.
- Battery Replacement: Replace batteries when the low battery indicator appears on the display. If the device will not be used for an extended period (more than one month), remove the batteries to prevent leakage.
- Disposal: Dispose of the device and batteries according to local environmental regulations.
10. Troubleshooting
If you encounter issues, refer to the following table:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display after pressing power button | Batteries are dead or incorrectly inserted. | Check battery polarity; replace with new AAA batteries. |
| Unstable or inaccurate readings | Finger not properly inserted, movement during measurement, strong ambient light, nail polish. | Ensure finger is fully inserted and still. Avoid movement. Shield from strong light. Remove nail polish. |
| Alarm sounds continuously | Readings are outside the set alarm limits. | Check current SpO2 and pulse rate. Adjust alarm limits if necessary. Consult a medical professional if readings are consistently low or high. |
| Device turns off automatically | Normal operation (auto-off after 8 seconds of inactivity) or low battery. | This is normal behavior. If it turns off during measurement, replace batteries. |
