A: Should we remove this patient's chest drain now?
It shows no pulmonary air leakage and drainage fluid is very clear, with little blood.
B:Hmm.... the volume of fluid yesterday was 400mL. It is a little bit large.
so Let us keep it till tomorrow.

Based on the information you provided, it seems that the patient's chest drain is functioning properly and there is no evidence of pulmonary air leakage.
However, the volume of drainage fluid was a bit high yesterday at 400mL.
It may be best to wait one more day before removing the chest drain to ensure that the drainage fluid continues to clear and there is no increased risk of complications.
