A pericardial effusion is the abnormal accumulation of fluid in the pleural space around the heart. It is commonly known as fluid around the heart. If there is an excessive collection of fluid, it may compress the heart and this is known as a cardiac tamponade. It is potentially life threatening in these cases.
A shot really refers to a portion of liquor being served in a shot glass, and the same is true for a jigger.. A pint is 16 fluid ounces and a fifth (as the name implies, 1/5 of a gallon) is 25.6 ounces. So for the three most commonly quoted sizes for a shot (1, 1.25, and 1.5 ounces), a pint is 16, 12.8, or 10.7 shots and a fifth is 25.6, 20.5, or 17 shots.

There is no standard unit of volume. In the US, a shot is 1.5 ounces and a small shot is 1 ounce of liquor for an alcoholic beverage such as whiskey. However, this varies internationally and there is no absolutely defined unit, and various sizes of glasses are used.
