Which statement regarding non-invasive ventilation is correct?

The statement that non-invasive ventilation can help to improve oxygenation in patients with respiratory failure is correct because non-invasive ventilation (NIV) is designed to support patients who are experiencing respiratory distress without the need for invasive procedures like intubation. NIV uses the patient's own airway and delivers positive pressure ventilation to maintain or improve ventilation and oxygenation.

NIV can effectively address various forms of respiratory failure, including conditions such as chronic obstructive pulmonary disease (COPD) exacerbations, acute cardiogenic pulmonary edema, and in some cases, hypoxic respiratory failure. By providing ventilatory support and improving alveolar ventilation, non-invasive methods can enhance oxygenation and also reduce the work of breathing for patients who are struggling to breathe effectively.

This contrasts with the other statements. For instance, non-invasive ventilation is not indicated for pulmonary barotrauma (as mentioned in option A), and it is often utilized in patients with obstructive sleep apnea—contradicting what is stated in option B. It also is specifically designed to avoid the need for intubation (which relates to option D), carrying the additional benefit of reducing the risks and complications associated with endotracheal tubes.
