SpO2 Knowledge Centre
Four working guides on pulse oximetry, sensor types and adapter selection, written for the people who specify and buy these consumables.
What Is an SpO2 Sensor and How Does Pulse Oximetry Work
How a pulse oximetry sensor measures oxygen saturation, the difference between transmission and reflectance sensors, and the factors that affect accuracy.
GuideDisposable SpO2 Sensors Explained Sizes Materials and Use Cases
What a single-patient-use SpO2 sensor is, how long it stays on a patient, the components inside it, and where disposables beat reusable sensors.
GuideHow to Choose an SpO2 Adapter Cable for Your Monitor
Why a matching plug shape does not guarantee a matching signal, the types of SpO2 adapter, and what to confirm before buying one.
GuideBasic Information for SpO2 Measurement
The essentials of peripheral capillary oxygen saturation: normal ranges, what the number means clinically and what it does not tell you.
About the Knowledge Centre
Who writes these guides
They are written by our own team from the questions buyers and biomedical engineers ask us most often.
Can I reuse this material for staff training
Yes, for internal clinical or technical training. Contact us if you want a version with your own branding.
Do the guides cover specific monitor models
The guides cover principles and selection. Model-specific compatibility lives on the individual product pages.
Still Not Sure Which Sensor You Need
Send us the monitor brand and model. A two-line message is usually enough for us to name the part.
