Fig. 2From: Patterns of pleural pressure amplitude and respiratory rate changes during therapeutic thoracentesisChanges in pleural pressure amplitude during pleural fluid (PF) withdrawal. Assessment points: 0 – baseline (before PF withdrawal), 1 - after aspiration of 25% of total PF volume, 2 - after aspiration of 50% of total PF volume, 3 - after aspiration of 75% of total PF volume, 4 - after aspiration of 100% of total PF volumeBack to article page
