Effects of Low Tidal Volume and Airway Pressure Release Ventilation on Lung Tissue Mechanics in ARDS Patients Under Mechanical Ventilation: A Prospective Randomized Crossover Study
The goal of this clinical trial is to learn how low tidal volume ventilation (LTV) and airway pressure release ventilation (APRV) affect lung tissue mechanics in adults with ARDS. The main questions it aims to answer are: Does LTV or APRV improve lung tissue mechanics in patients with ARDS under mechanical ventilation? Researchers will compare LTV and APRV to see which ventilation mode works better for improving lung mechanics and patient safety.
