How is oxygen typically delivered to patients in a healthcare facility?

Oxygen is typically delivered to patients in healthcare settings primarily through devices specifically designed to administer oxygen directly to the respiratory system. This includes nasal cannulas, which are small tubes that fit into the nostrils and allow patients to receive supplemental oxygen while remaining comfortable and mobile. Face masks can be used for patients who need higher concentrations of oxygen or who have difficulty breathing through their nose. Mechanical ventilation systems, such as ventilators, provide oxygen to patients who are unable to breathe effectively on their own, delivering it through a tube inserted into the trachea.

The methods of delivery that involve oral syringes, pills, or injections are not appropriate for oxygen, as oxygen must enter the respiratory system rather than the gastrointestinal or circulatory systems for effective utilization. Similarly, intravenous fluids are used for hydration and medication administration, not for oxygen delivery. Therefore, the correct choice accurately reflects the standard practices in administering oxygen therapy within a healthcare facility.
