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.
Recently purchased split peas may be ready in 45â60 minutes, depending on how mushy you like them. If they've been in storage for a while, they may take up to 90 minutes or even 2 hours. Aim to add the vegetables about 30 minutes before the peas are finished.
