Intrathoracic pressure has been known to increase in patients with raised intra-abdominal pressure and the Trendelenburg position (10) Accordingly, the usefulness of PPV and SVV, which are affected by changes in intrathoracic pressure, in predicting fluid responsiveness during laparoscopic surgery under these conditions may be questioned.
As the patient had chronic cough, a day later, the increased intrathoracic pressure caused his lung to herniate during a coughing spell.

Hepatic vein flow patterns are under the effects of cardiac function and intrabdominal and intrathoracic pressure.
Intrathoracic pressure can be transmitted from the lungs to the pulmonary vessels and change the intraluminal pressure (Marino, 2007).
In patients with OSA, the abrupt and repetitive inspiratory effort against a closed upper airway during the apnoeic episodes generate changes in negative intrathoracic pressure that increase transmural gradients across the atria, ventricles and aorta (35,36) and may disrupt ventricular function (35).
We must also be aware that the Trendelenburg position increases intrathoracic pressure, impairing venous return and accentuating the change in functional residual capacity.
Inspiratory resistance induced by breathing through an impedance threshold device (ITD) reduces intrathoracic pressure and increases stroke volume (SV) in supine normovolemic humans.
Significant haemodynamic changes were found in an animal model resulting from the lengthy increase in intrathoracic pressure and the decrease in cardiac deficit and compensatory vasoconstriction that is evident from the increase in systemic vascular resistance and mean arterial pressure (Anning et al 2003).
Another important pathophysiology in OSA relates to the increased negative intrathoracic pressure generated by attempting to inhale against a collapsed airway.
Mechanically ventilated patients have a higher mean CVP, which is more indicative of mean intrathoracic pressure than of cardiac filling or intravascular fluid status.
High intrathoracic pressure increases central venous pressure and pulmonary artery wedge pressure without increasing the right or left ventricular end-diastolic volume.
According to this theory, increased intrathoracic pressure or the change in intrathoracic pressure during chest compressions forces blood from the thoracic vessels into the systemic circulation, with the heart acting as a conduit and not as a pump.
A possible complication includes tension PM, which has been induced in laboratory animals by a continued increase in intrathoracic pressure.
The increased intrathoracic pressure is transiently transmitted to the superior vena cava and cerebral venules and capillaries, perhaps leading to a brief increase in oxygen availability.
