What is the term for the device that delivers specific oxygen concentrations during ventilation?

The device that delivers specific oxygen concentrations during ventilation is known as an oxygen blender. This instrument is essential in clinical settings, particularly in the management of patients who require precise control over their supplemental oxygen levels. Oxygen blenders mix room air with concentrated oxygen to create a desired FiO2 (fraction of inspired oxygen), allowing healthcare providers to tailor oxygen delivery to meet a patient's specific respiratory needs.

Unlike an oxygen concentrator, which primarily focuses on extracting oxygen from ambient air and delivering a high concentration of oxygen, an oxygen blender allows for the flexibility of adjusting the ratios of oxygen and air. This is crucial when precise oxygen delivery is required, as in the case of mechanically ventilated patients or those undergoing certain medical treatments. Therefore, the oxygen blender plays a pivotal role in ensuring optimal oxygen therapy tailored to individual patient requirements.
