A nurse is providing care to a patient diagnosed with abdominal compartment syndrome.

Abdominal compartment syndrome (ACS) involves increased intra-abdominal pressure, which can significantly impact various body systems. One of the major concerns is its effect on respiratory function, leading to increased peak inspiratory pressure. This happens because the elevated pressure in the abdomen can push up against the diaphragm, making it harder for the lungs to expand during inhalation. Increased urine output is unlikely as ACS usually leads to decreased renal perfusion and output. Increased preload and decreased intracranial pressure are not typically associated with ACS.
