Chest Tubes After Open Heart Surgery. When a patient has a chest tube after heart surgery, the tube is inserted near the sternum (breastbone), and is intended to drain any blood that accumulates away from the surgery site.
Currently there are five major types of sorghum grown: 1) Grain sorghum with dwarf varieties that grow 2 to 5 ft tall for easier combining. 2) Forage sorghum which grows 6 to 12 ft tall, produces more dry matter tonnage than grain sorghum, is coarse stemmed and used for silage.
Figure 1*. Figure 2* - Global Sorghum Production Map. The top sorghum producing countries (see Figure 1) are the United States (17% of the world production), Nigeria, India (each with 14%) and Mexico (11%). The US population consumes most sorghum through intermediary livestock that consumes it, but the prevalence of sorghum in many other countries (see Figure 2), such as South America and Africa, indicate the areas where human nutrition depends heavily on grain sorghum.
