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.
Introduction. Home blood sugar (glucose) testing is an important part of controlling blood sugar for people with diabetes. One important goal of diabetes treatment is to keep the blood glucose levels near the normal range of 70 to 120 mg/dl before meals and under 140 mg/dl at 2 hours after eating. 1  Blood glucose levels are usually tested before and after meals, and at bedtime.
