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.
Symptoms depend on which area of the body is most involved in the reduced pumping action. When the left side of the heart (left ventricle) starts to fail, fluid collects in the lungs (edema). This extra fluid in the lungs (pulmonary congestion) makes it more difficult for the airways to expand as a person inhales.
