What is a common route for administering oxygen to patients in a hospital setting?

In a hospital setting, administering oxygen via a nasal cannula (NC) is a common route because it allows for effective delivery of supplemental oxygen directly into the patient's nostrils. This method is non-invasive, easy to use, and comfortable for the patient, making it suitable for those requiring a moderate level of oxygen supplementation. The nasal cannula can provide a variable flow of oxygen ranging from low to moderate concentrations, which can be adjusted based on the patient's needs and Oxygen saturation levels.

This approach is particularly advantageous in emergency and critical care settings where maintaining adequate oxygen levels is crucial. It allows for simultaneous oral intake and communication, which can be particularly beneficial in a hospital environment. While various other methods of oxygen delivery exist, such as face masks or mechanical ventilation, the nasal cannula's simplicity and effectiveness in many situations make it a staple in oxygen therapy protocols.
