Study of Effects of SIMV, CPAP, and BiPAP Ventilation Modes on Intra-Abdominal Pressure, Mechanical Power, and Gastric Tube Tolerance in Mechanically Ventilated Adults in ICU

What this Trial Is About

This research aims to explore how different mechanical ventilation modes affect intra-abdominal pressure IAP, mechanical power MP, and gastric tube tolerance in adults who require mechanical ventilation in the intensive care unit ICU. The study focuses on three commonly used ventilation modes SIMV, BIPAP, and CPAP, investigating their impact on respiratory mechanics and overall body system functions. Participants are divided into three groups based on the ventilation mode used SIMV, CPAP, or BiPAP. Each group receives mechanical ventilation through the assigned mode while being monitored for the effects on intra-thoracic pressure and related physiological responses. The study observes the participants primarily on the first day of ventilation to assess IAP, mechanical power, and gastric tube tolerance. During the study, participants are monitored closely for the specified outcomes including intra-abdominal pressure, mechanical power, and gastric tube tolerance on day one. The assessments help understand how the ventilation mode influences these parameters. Participants are adults between 18 and 60 years old who require mechanical ventilation in the ICU. The study lasts from August 2026 to November 2026, with data collection and monitoring occurring during this period.
