Peripheral edema is also something that hospital physical therapists need to assess and document in a way which enables future comparison. Typically edema is also discussed by noting level (i.e., 2+ pitting edema, approximately to mid-shin bilaterally), and limb girth can also be measured and recorded, particularly when asymmetric. https://onlinejcf.com/article/S1071-9164(13)00464-8/fulltext
There are many more important parts of assessing peripheral circulation and cardiopulmonary dysfunction by physical exam, but these are entry-level assessment items through which any hospital therapist can add information to the care team’s judgment of a patient’s clinical status.
