Q

Protein deficiency alters osmotic pressure allowing fluid to move from within the vasculature to the interstitium which impairs healing in 2 ways, what are they?

A

1) edema decreases oxygen’s ability to diffuse into the affected area
2) the pressure created by the edema can restrict blood flow within the affected area, further decreasing the availability of oxygen and allowing the accumulation of metabolic waste products
