Which statement describes an indication for Non-Invasive Positive Pressure Ventilation (NIPPV)?

• A. Indicated for any adult with respiratory distress regardless of underlying condition.
• B. Indicated in adults with CHF and pneumonia if two of: retractions or accessory muscle use; respiratory rate > 25 per minute; SpO2 ≤ 94%.
• C. Indicated for any patient with major trauma or vomiting.
• D. Indicated only after endotracheal intubation.

Answer: (B)

Noninvasive Positive Pressure Ventilation is used for patients with acute respiratory distress due to conditions like congestive heart failure–related pulmonary edema or pneumonia, but only when they show signs that they are likely to benefit from noninvasive support and can protect their airway. The key screening criteria help identify those who still have the ability to cooperate with the mask and who have enough respiratory compromise to warrant assistance, yet are not so unstable that NIV would fail or delay appropriate care. Specifically, you look for two of the following: use of retractions or accessory muscles indicating increased work of breathing, a respiratory rate greater than 25 breaths per minute showing tachypnea, and a oxygen saturation of 94% or lower indicating hypoxemia. When two of these are present in the appropriate clinical context, NIPPV can improve ventilation and oxygenation, reduce the work of breathing, and may help avoid intubation, provided there are no contraindications and the patient can maintain airway patency and cooperation. The other scenarios aren’t aligned with when NIV should be used: not every adult in distress qualifies, major trauma or vomiting aren’t indications for NIV, and NIV is not used after endotracheal intubation.
