How to Use a Medical SpO₂ Sensor?

A Medical SpO₂ Sensor is a vital accessory for monitoring a patient’s blood oxygen saturation and pulse rate. To ensure accurate results and safe operation, proper usage is essential in both clinical and homecare settings.

Step 1: Device Compatibility
Before use, confirm that the SpO₂ sensor is compatible with the patient monitor, pulse oximeter, or other equipment. Using the correct connector type ensures stable signal transmission.

Step 2: Sensor Placement
Attach the sensor to a suitable measurement site such as a finger, toe, or earlobe. For neonatal patients, sensors are often placed on the foot or palm. Ensure that the area is clean, warm, and free from nail polish or artificial nails, as these may interfere with light transmission.

Step 3: Proper Fitting
The probe should fit snugly but not too tightly, as excessive pressure may restrict blood flow and distort readings. Soft silicone or cloth-based sensors are recommended for long-term monitoring due to their comfort and flexibility.

Step 4: Monitoring and Observation
Once attached, the sensor emits light to measure oxygen levels through the skin. Keep the patient still during measurement to reduce motion artifacts. Monitor the displayed values and ensure the waveform is stable.

Step 5: Maintenance and Care
Reusable sensors should be cleaned and disinfected according to manufacturer instructions. Avoid harsh chemicals that may damage the optical components. For infection control, disposable sensors should be discarded after single use.

By following these steps, healthcare providers and caregivers can ensure accurate, safe, and reliable SpO₂ monitoring, supporting better clinical decision-making and patient care.
