Final answer:
In obstructive shock, CVP, PAP, and PCWP may be affected. CVP may increase due to impaired venous return, PAP may increase due to increased resistance in the pulmonary circulation, and PCWP may be elevated due to impaired left ventricular filling.
Step-by-step explanation:
In a person with obstructive shock, the CVP (central venous pressure), PAP (pulmonary artery pressure), and PCWP (pulmonary capillary wedge pressure) may be affected.
- CVP: In obstructive shock, CVP may increase due to the blockage in the vascular system causing impaired venous return to the heart.
- PAP: PAP may also increase as a result of increased resistance in the pulmonary circulation due to the obstruction.
- PCWP: PCWP may be elevated due to impaired left ventricular filling caused by the obstruction.
These pressures are important indicators of cardiac function and can help healthcare providers in diagnosing and managing obstructive shock.
