Intraabdominal Hypertension and Occurrence of Microaspiration in Cirrhotics Under Mechanical Ventilation

This study is examining whether increased pressure inside the abdomen — common in patients with liver cirrhosis — makes it more likely for tiny amounts of stomach contents to accidentally enter the lungs (called microaspiration) in patients on a breathing machine. **You may be eligible if...** - You are an adult patient - You have liver cirrhosis - You are on a mechanical ventilator (breathing machine) **You may NOT be eligible if...** - You are pregnant - You have very low urine output (oliguric) - It is not possible to measure the pressure inside your bladder (used to estimate abdominal pressure) Talk to your doctor to see if this trial is right for you.
