The thoracic‐pulmonary mechanic model (TPMM) is a teaching tool used to better understand the changes in pulmonary and intrapleural pressures during thoracic respiratory movements. Here, we used the model to explain how the intrapleural pressures during the respiratory movements coupled to water seal chest drainage (WSCD) results in an effective solution for pneumo and hydrothorax. Pressures were measured by using equipment and computational MP150 AcqKnowledge software from Biopac Systems Inc. Table shows the pulmonary and intrapleural pressures in basal, pneumothorax and hydrothorax conditions and in solved pneumo and hydrothorax conditions. In conclusion, the TPMM‐WSCD model is useful to understand the physics of the pulmonary ventilation and the principles of the WSCD.Pulmonary pressure (mmHg) Intrapleural pressure (mmHg)TPMM‐WSCD Basal conditions (no breath) 0.50 −4.40 Pneumothorax 0.51 0.28 Pneumothorax solved 0.48 −4.21 Hydrothorax 0.48 2.61 Hydrothorax solved 0.47 −7.11Supported by UAA.
