Pulse oximeters have revolutionised modern healthcare by offering a quick, non-invasive method to assess oxygen saturation levels. These compact medical devices provide critical insights into a patient’s respiratory health, helping clinicians detect and respond to conditions like hypoxia, respiratory distress, and chronic lung diseases.

Selecting the right pulse oximeter can be challenging, especially with so many options available. Whether you're a healthcare professional needing reliable medical equipment for clinical use or a home user monitoring your health, understanding key features is crucial.
