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: What Happens to the Body. Every part of your body needs oxygen. Your lungs take in oxygen when you breathe. It is the heartâs job to pump blood to the lungs to pick up oxygen, and then to pump this blood to every part of your body. The heart has two independent pumping systems, one on the right side and one on the left side. Each of these systems has 2 chambers: An atrium (pronounced AY-tree-um).
