Divide mileage by fuel usage to see your car's fuel consumption. This tells you how many miles you drove per gallon of gas. For example, if you drove 335 miles before refueling, and you filled your car up with 12 gallons of gas, your fuel consumption was 27.9 miles per gallon, or mpg (335 miles / 12 gallon = 27.9 mpg).
Failure on the left side is linked to a general weakening of the heart muscle. This is the more common type of heart failure. The weakened heart muscle no longer can keep up with the demands of the body for oxygen-rich blood. Back-up into the lungs occurs. Symptoms of left-side heart failure include: 1  Tiredness (fatigue). 2  Shortness of breath. 3  Asthma-like wheezing.
Heart failure occurs when the heart muscle is not able to function in a manner that can sufficiently supply the body with oxygen. Congestive heart failure is the failure of the heart muscle to maintain the circulation, leading to a backup of blood in the veins that causes: swelling (particularly in the lower parts of the body); shortness of breath is another common symptom of congestive heart failure that occurs due to fluid buildup in the lungs; and
