Abstract:
A 71-year-old man presented to our hospital for dyspnea lasting for the past 3 days. Chest X-ray and computed tomography demonstrated right tension pneumothorax, and an electrocardiogram suggested acute inferior myocardial infarction. Despite the relief of tension pneumothorax, the electrocardiographic findings were not completely resolved. Emergency coronary angiography demonstrated an occlusive lesion in the right coronary artery, and percutaneous coronary intervention was performed successfully. Thereafter, the chest tube was removed, and he was discharged. While rare, multiple life-threatening diseases that present with similar symptoms can coexist, so a re-evaluation after performing the initial treatment for one of these diseases is crucial.

Pneumothorax-I
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

Surface Tension, Capillary Action, and Viscosity
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
