In this article, we will discuss about Tension Pneumothorax. So, let’s gets started
In tension pneumothorax, the mean pleural pressure is positive which means that air in the pleural cavity is under tension which causes compression collapse of the lung. It develops due to persistent air leak (air entry) inside the pleural cavity by the communication which opens during inspiration and closes during expiration preventing the air to escape. In this way, with each successive breath, the intrapleural pressure increases which eventually causes the mediastinum to shift to the opposite side and increased intrapleural pressure also puts pressure on the surrounding blood vessels.
There is decreased venous return to the heart and along with decreased cardiac output causing hypotension (cardiac tamponade) and cyanosis.
Dyspnea, cough and acute exacerbation of pneumothorax symptoms
Trachea and mediastinum shifts to the opposite side
Decreased or absent breath sounds, there may be amphoric breathing present at a localized place.
Hyperinflated chest with decreased or absent chest wall movement of the involved side
Tachypnea, tachycardia, hypotension, cyanosis, and paradoxical pulse.
