Recruitment Maneuver After Bronchoalveolar Lavage in ARDS Patients

Recruitment Maneuver After Bronchoalveolar Lavage in ARDS Patients

ARDS caused by pneumonia is one of the main reasons for ICU admission in critically ill patients, and also a common complication in patients admitted to ICU with invasive mechanical ventilation. Bronchoalveolar lavage (BAL) is the main diagnostic method for these patients, which often leads to alveolar collapse and exacerbates hypoxemia. In clinical practice, recruitment maneuver (RM) is often used immediately after BAL to prevent such a situation, but there is a lack of data on RM after BAL.

Inclusion Criteria:

2. Patients who diagnosed with ARDS according to the Berlin definition
