Closed space: The chest cavity is a closed space so if there is a puncture in the lung, air escapes through the lining of the lung into the surrounding chest cavity. Since it can't escape, the pressure increases pushing everything to the other side of the chest, including the heart. Decompression with a needle or tube is then necessary to relieve the pressure and allow the heart to shift back into place.

Pressure: The pressure from a "tension pneumothorax" pushes heart towards the opposite side of the chest. This tension/compression can be sufficient to prevent adequate blood from entering the right side of the heart. This can result in rapidly fatal consequences unless decompression is achieved.

Balloon effect: Pneumo=air; thorax=chest This is a situation where air enters between the internal chest wall & the lungs creating a balloon like cavity under pressure.Depending on the amount of air & pressure, it can push the lungs flat & move the heart over.Take out the extra air and pressure & it returns to normal.
