The contraindication for the use of the Pneumatic Anti-Shock Garment (PASG) primarily includes pulmonary edema because this condition involves fluid accumulation in the lungs, which can be exacerbated by the application of the garment. The PASG is designed to compress the lower body to control hemorrhage and improve circulation during shock, but in cases of pulmonary edema, the added pressure can hinder respiration and further compromise the patient's ability to breathe.

In contrast, an impaled abdomen, a pelvic fracture, or penetrating thoracic injuries may not necessarily preclude the use of a PASG, as its primary function involves managing severe pelvic and lower extremity hemorrhages or shock. However, each case requires careful assessment and consideration of the patient's overall condition and potential for compromise before applying the PASG. Therefore, the critical factor with pulmonary edema is that it can significantly worsen the respiratory status of the patient if the garment is used.
