The HHR is a stylish retro wagonette based on the Chevrolet Cobalt platform. Introduced in 2006, it offers more interior space and better looks than the Cobalt, although the roughly $3000 premium for the HHR is not insubstantial.
Congestive heart failure. The most common cause of pulmonary edema is congestive heart failure (CHF). Heart failure is when the heart can no longer pump blood properly throughout the body. This creates a back-up of pressure in the small blood vessels of the lungs, which causes the vessels to leak fluid.
Pulmonary Edema Overview. Pulmonary edema literally means an excess collection of watery fluid in the lungs. (pulmonary=lung +edema=excess fluid). However, the lung is a complex organ, and there are many causes of this excess fluid accumulation. Regardless of the cause, fluid makes it difficult for the lungs to function (to exchange oxygen and carbon dioxide with cells in the bloodstream). Air enters the lungs through the mouth and nose, traveling through the trachea (windpipe) into the bronchial tubes.
