Which statement about non-invasive positive pressure ventilation is false?

• A. It requires a conscious, cooperative patient
• B. It protects the airway by bypassing the endotracheal tube
• C. ARDS patients are usually not cooperative
• D. It can be used for COPD exacerbations

Answer: (B)

Non-invasive positive pressure ventilation delivers support through a mask or helmet, not through an endotracheal tube. Because there is no airway tube to bypass, it does not provide airway protection in the same way intubation does. That’s why the statement about protecting the airway by bypassing the endotracheal tube is not correct. In practice, airway protection remains limited with NIV, and the patient’s own protective reflexes are relied upon. NIV does require a conscious, cooperative patient, since the interface must be tolerated and the patient must be able to cooperate with the breathing pattern. It’s a common therapy for COPD exacerbations, aimed at avoiding intubation and reducing work of breathing and respiratory failure. In ARDS, NIV is used less often because success rates are lower and many patients progress to invasive ventilation, though cooperation per se isn’t the defining factor.
