Explanation
A. Mr. Milby states his pain level is a 0/10
This indicates good pain control, which is expected and desired postoperatively.
B. Head of bed is elevated 45 degrees
Elevation this high may cause improper alignment and interfere with the machine’s function. Typically, HOB should be no more than 20-30 degrees during CPM use.
C. Mr. Milby complains of "tightness" of incision when CPM machine is at maximum flexion
This could indicate excessive tension on the wound or early signs of complications like swelling or dehiscence.
D. All side rails on Mr. Milby’s bed are down
This is a safety hazard. At least one or two side rails should be up during machine use to prevent falls.
E. The knee dressing is loose and not adhering on all sides
Loose dressings may indicate poor wound protection and risk for infection or wound exposure.
F. The machine is set to 45 degrees of flexion
This is per the physician’s order and indicates proper settings.
