An AC system has many components: compressor, condenser, receiver dryer, evaporator, and hoses. The compressor, the âheartâ of the carâs air conditioning system works like a pump taking refrigerant, (R-12 in older cars, R-134a in 1995 and newer cars) and pressurizing it, passing it along to the evaporator. The AC compressor has several moving parts (including pistons and valves).
They vary throughout the day. (Click here for a blood sugar chart.) For someone without diabetes, a fasting blood sugar on awakening should be under 100 mg/dl. Before-meal normal sugars are 70â99 mg/dl. âPostprandialâ sugars taken two hours after meals should be less than 140 mg/dl. Those are the normal numbers for someone without diabetes.
Keep your blood sugar levels close to normal to prevent many of these complications. The American Diabetes Association's goals for blood sugar control in people with diabetes are levels of 70 mg/dL to 130 mg/dL before meals, and less than 180 mg/dL after meals. The organ overcompensates and insulin levels remain too high. 2  Over time, the pancreas is permanently damaged. 3  High levels of blood sugar can cause changes that lead to a hardening of the blood vessels, what doctors call atherosclerosis.
