What is the flow range of a nasal catheter to deliver oxygen?

The correct range for delivering oxygen via a nasal catheter is typically between 1-5 L/min. This range is significant because it allows for adequate oxygen delivery while minimizing the risk of discomfort or nasal mucosa irritation. Nasal catheters are designed to provide a low-flow supplemental oxygen option, which can be beneficial for patients who require oxygen therapy but do not need a high concentration of oxygen, maintaining a balance between patient comfort and therapeutic needs.

While the other ranges provided in the incorrect options might reflect other forms of oxygen delivery or may contain inaccuracies in measurement, the established flow rate for nasal catheters is essential for ensuring the effective treatment of patients with respiratory issues. This correct flow rate enables healthcare professionals to adjust oxygen delivery based on individual patient requirements, making it a critical aspect of optimal respiratory care.
