Inflammation of the lungs and bronchial tubes are also common causes of shortness of breath, as is injury to the respiratory tract caused by smoking or other toxins. Shortness of breath may occur with injury to the lungs, such as a collapsed lung (pneumothorax).
In the United States, pea soup without qualification usually means a perfectly smooth puree. Split Pea Soup is a slightly thinner soup with visible peas, pieces of ham or other pork, and vegetables (most commonly carrots) and is usually made from dried, green split peas.
Place the rinsed split peas in the slow cooker. Add the ham bone and remaining ingredients. Now add 6 cups of water. Cover, and cook on high for 4 to 5 hours or low for 8 to 10 hours. When the peas are very soft and the ham is falling off the bone, the soup is ready.
