Introduction
The document provides technical specifications and operational guidelines for a handheld pulse oximeter, a medical device used to measure oxygen saturation levels in the blood and pulse rate.

Specifications
The pulse oximeter is designed for portability and ease of use. Key specifications include:

• Measurement Range: Oxygen saturation (SpO2) from 70% to 100%.
• Pulse Rate: 30 to 250 beats per minute.
• Accuracy: SpO2 accuracy of ±2% and pulse rate accuracy of ±3 bpm.
• Display: LED screen showing SpO2, pulse rate, and plethysmograph.
• Power Supply: Operates on two AAA batteries with a battery life of approximately 30 hours.

Procedures
Instructions for use include:

• Ensure the device is powered on and the sensor is clean.
• Place the sensor on the patient's fingertip, ensuring proper alignment.
• Wait for the readings to stabilize before recording the results.

Standards and Compliance
The device complies with international standards for medical devices, including ISO 80601-2-61 for pulse oximeters.

Recommendations
For optimal performance, it is recommended to:

• Regularly calibrate the device according to the manufacturer's guidelines.
• Store the device in a cool, dry place when not in use.
• Replace batteries promptly when low to ensure accurate readings.

Conclusion
The handheld pulse oximeter is a reliable tool for monitoring patient oxygen levels and pulse rate, suitable for both clinical and home use. Proper maintenance and adherence to operational guidelines will ensure its longevity and accuracy.
