Pulmonary edema grading

Dr Craig Hacking and A.Prof Frank Gaillard et al.

One grading system on pulmonary edema based on chest radiograph appearances and pulmonary capillary wedge pressure (PCWP) is as follows:

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