From: Esophageal pressure as estimation of pleural pressure: a study in a model of eviscerated chest
Swine model of eviscerated chest. Figure shows the swine model of eviscerated chest where all the thoracic organs were removed while preserving the esophagus. The light blue area represents the inelastic plastic bag adhering to the chest wall and sealed to an endotracheal tube. The intrathoracic pressure was measured through a dedicated catheter (in blue). The esophageal pressure was measured through two different esophageal catheters (in green)
