The HFOV Golden Rule for managing situations involving pulmonary interstitial emphysema (PIE) or air leak emphasizes the importance of maintaining the same mean airway pressure (MAP) as conventional ventilation while adjusting other parameters, such as oxygenation levels. By keeping the MAP consistent with conventional ventilation, you ensure that adequate lung inflation is maintained, helping to improve oxygenation without contributing to further lung injury or exacerbating the air leak.

Maintaining the same MAP also allows for optimal recruitment of alveoli while minimizing barotrauma, which is crucial in delicate neonatal lungs. Adjusting oxygen levels while keeping MAP stable helps to respond to changes in oxygen saturation without compromising lung mechanics, presenting a more balanced approach to managing ventilation in neonates experiencing these complications.

In contrast, increasing PEEP above conventional ventilation settings can lead to increased pressure and potentially worsen air leaks. Setting a higher frequency might not address the underlying need for adequate MAP and could lead to respiratory alkalosis or other complications. Decreasing PIP could insufficiently support the lung mechanics required in the presence of PIE or air leaks, leading to inadequate ventilation.

Thus, the key principle in the management of PIE or air leak under HFOV is to prioritize maintaining a stable MAP similar to conventional ventilation while making necessary oxygen
