CHAPTER EIGHTEEN. Hyperbaric Oxygen Therapy
++
++
++
In order to be considered hyperbaric therapy, pressure must be
++
++
++
a. Above one atmosphere absolute.
++
++
b. Greater than 1.4 atmosphere absolute.
++
++
c. Between 2 and 3 atmosphere absolute.
++
++
d. Either inhaled or topical.
++
++
++
Hyperbaric oxygen therapy is physiologically effective in increasing skin perfusion because it
++
++
++
a. Causes vasodilation of the distal vessels.
++
++
b. Increases the blood flow to the extremities by increasing the blood pressure.
++
++
c. Increases the oxygen dissolved in the plasma and tissues.
++
++
d. Dissolves the fibrinogen clots in occluded arteries.
++
++
++
Studies of HBOT on diabetic patients has shown that there is an increase in
++
++
++
a. Platelet-derived growth factors and fibroblast production.
++
++
b. Migration of macrophages to the injured tissue.
++
++
c. Collateral circulation in the affected extremity.
++
++
d. Histamine with resulting increased vasopermeability.
++
++
++
In order for Medicare to cover HBOT for a diabetic foot wound, it must be classified as a
++
++
++
++
++
++
++
++
++
++
++
++
Which of the following is an absolute contraindication to HBOT?
++
++
++
++
