What is a potential complication of PASG use in a patient with pulmonary edema?

1. improved respiratory function

2. worsening of edema

3. increased cardiac output

4. decreased blood pressure

The correct answer is: worsening of edema

The use of a pneumatic anti-shock garment (PASG), now often referred to as a multi-purpose compression device, can have various effects on a patient with pulmonary edema. In this scenario, one notable complication is the potential for worsening of edema. Pulmonary edema is characterized by excess fluid in the lungs. When PASG is applied, it exerts pressure on the abdominal cavity and lower extremities, which can lead to a redistribution of fluids in the body. For a patient already struggling with pulmonary edema, the application of PASG may increase the pressure in the thoracic cavity, potentially compromising respiratory function and exacerbating fluid redistribution issues. This can further increase the amount of fluid in the lung interstitium and alveoli, worsening the patient's pulmonary edema and leading to increased respiratory distress. In contrast, options like improved respiratory function, increased cardiac output, and decreased blood pressure would not typically occur with the use of PASG in a patient with pulmonary edema. These alternatives do not align with the physiological responses expected from such a device in this specific clinical situation.
