Which statement correctly describes common delivery methods for oxygen therapy?

Non-invasive ventilation is the only method Oxygen must be given by IV infusion Oxygen therapy is provided only as a nasal spray Common delivery methods include nasal cannula, simple face mask, non-rebreather, Venturi mask, CPAP/BiPAP as indicated

Correct Answer:

Common delivery methods include nasal cannula, simple face mask, non-rebreather, Venturi mask, CPAP/BiPAP as indicated

Explanation:

Oxygen therapy is delivered through a range of devices that control how much oxygen reaches the patient and whether any ventilation support is needed. A nasal cannula provides a comfortable, low-flow option for modest oxygen needs. A simple face mask increases the concentration of delivered oxygen when more support is required. A non-rebreather mask can supply high concentrations of oxygen when flow and reservoir conditions are appropriate. A Venturi mask offers a precise, fixed oxygen concentration using different adapters, which is helpful when exact FiO2 is important. For patients who need help with breathing in addition to oxygen, CPAP or BiPAP provides non-invasive ventilation, delivering positive airway pressure to support ventilation.
