Case Discussion

Pulmonary edema is graded depending on chest x-ray and pulmonary capillary wedge pressure (PCWP) is as follows:

  • grade 0: normal chest radiograph, PCWP 8-12 mmHg
  • grade 1: upper lobe diversionon a chest radiograph, PCWP 13-18 mmHg
  • grade 2: interstitial edema on a chest radiograph, PCWP 19-25 mmHg
  • grade 3: alveolar edema on a chest radiograph, PCWP >25 mmHg

Our case is representing grade 2 pulmonary edema.
