Esophageal balloon group
Esophageal balloon will be inserted, and esophageal pressure will be measured in patients with acute respiratory failure.
Intervention - PEEP and Inspiratory pressure will be adjusted according to the measured esophageal pressure.
Other: esophageal balloon
esophageal pressure as a surrogate for pleural pressure
Other Name: pleural pressure
Identifying the dominant factor affecting respiratory system compliance by measuring transpulmonary pressure may better direct and optimize mechanical ventilation. Thus, instead of limiting mechanical ventilation by plateau pressure, PEEP and Inspiratory pressure adjustment would be individualized specifically for each patient's lung compliance as indicated by transpulmonary pressure.
The main goal of this approach is to specifically target transpulmonary pressure instead of plateau pressure, and therefore achieve the best Lung compliance with the least transpulmonary pressure possible.
