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.

RM after BAL
the ratio of tidal volume in the BAL side and the other side
distribution of tidal volume monitored by electrical impedance tomography from the BAL side to the other side
Time frame: up to 24 hours
partial pressure of arterial oxygen (Pao2) to the fraction of inspired oxygen (Fio2) ratio
partial pressure of arterial oxygen (Pao2) to the fraction of inspired oxygen (Fio2) ratio
Time frame: up to 24 hours
respiratory system compliance (the tidal volume to the driving pressure ratio)
respiratory system compliance was calculated by dividing expiratory tidal volume by the driving pressure (plateau pressure minus positive end-expiratory pressure)
Time frame: up to 24 hours
