PCWP (mm Hg) | Phase of Pulmonary Congestion | Findings on Chest Radiograph |
18–20 | Onset of pulmonary congestion | Redistribution of pulmonary flow to the upper lobes ("cephalization") and Kerley lines |
20–25 | Moderate congestion | Diminished clarity of the borders of medium-sized pulmonary vessels ("perihilar haze") |
25–30 | Severe congestion | Radiolucent grapelike clusters surrounded by radiodense fluid ("periacinar rosette") |
>30 | Onset of pulmonary edema | Coalescence of periacinar rosettes resulting in "Bat's wing" opacities |
