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.
Doctors will typically use either the fasting plasma glucose test (FPG) or the oral glucose tolerance test (OGTT). These tests require the patient to fast overnight. A normal fasting blood glucose level is below 100 mg/dl-between 100 and 125 mg/dl a person has pre-diabetes.If the blood glucose level rises to 126 mg/dl or above, a person has diabetes. When it comes to the OGTT test, a person's blood glucose is measured after a fast and 2 hours after a drink rich in glucose.octors will typically use either the fasting plasma glucose test (FPG) or the oral glucose tolerance test (OGTT).
