From: Postoperative air leak grading is useful to predict prolonged air leak after pulmonary lobectomy
Grade | Definition |
|---|---|
0 | No air bubble on three serial volitional coughs |
1 | More than one air bubbles on three serial volitional coughs |
2 | Persistent air bubbles on volitional coughs |
