Lung volume changes

Case contributed by Dr Jeremy Jones

Presentation

24 week preterm neonate with RDS.

Patient Data

Age: 24/40 day 4
Gender: Male
Modality: X-ray

Preterm neonate (24/40) with widespread alveolar and interstitial opacification and areas of collapse.  Almost no aerated lung demonstrated lung. Features of RDS.

Modality: X-ray

One day later, after a PDA ligation and chest drain insertion, there has been a significant change in appearance.

The lungs are hyperexpanded with persistent interstitial opacification.

Features here are the result of change in ventilator settings.

Modality: X-ray

Slight reduction in lung volumes after a further change in ventilator settings.

Case Discussion

Case of severe RDS in a neonate. The three radiographs demonstrate how the ventilator settings can significantly change the appearance of the "classical" appearance of RDS on the initial film.

It is a reminder that while RDS should never be diagnosed when lung volumes are normal or high, if the neonate is ventilated, all bets are off!
