Got Diabetes and Wondering How Your Blood Glucose Monitor Actually Works?


Are you one of the increasing number of people with diabetes who needs to monitor their blood sugar levels at home. If so, it is important to know how the tests work and what can effect the results giving inaccurate readings.

Diabetes Mellitus is a widespread disease that is caused by high blood glucose. However, it is not extremely difficult to cure and there have been cases of patients recovering from diabetes and continuing a normal life. There are many ways to control and monitor diabetes. For a long time, urine has been used as a way to check the amount of glucose in the body. However, it is no longer considered reliable. In its place, now blood is used. A machine that is now very commonly used to evaluate abnormal and normal blood glucose level is the Blood Glucose Monitor.

A blood glucose monitor or glucose meter is a small portable battery-powered electronic device that now comes in several models. The glucose meter is used to determine the deviations from the normal blood glucose level. The glucose test and the glucose reading are used to diagnose diabetes. These machines provide glucose readings from 0 to 600 mg/dl. Newer models now allow people to use blood from places other than the fingertip, which is the most common place from which it is extracted. Some models have large digital display and even spoken instructions for people with visual problems. Some models require smaller drops of blood than others. One must be careful while choosing a model, as it is an expenditure that has to be thought over. It is advisable to discuss with other users before buying one as all models have their pluses and minuses.

A blood glucose meter is an instrument that can be used even at home. This Blood glucose meter is used for taking a glucose test and it is a must have for those undergoing diabetes treatment. There is usually a special coated strip on which a drop of blood is placed. The blood is usually taken from the fingertip using a lancing device, which shoots a small, lancet into the skin. However, it is not necessary for it to be taken from the fingertip and sometimes blood is taken from other places like the forearm, thigh, calf or upper arm as the fingertip often gets calloused and sore. The blood is placed on the opposite side of the strip though this depends on the blood glucose meter. Then this strip is inserted into the blood glucose meter.

The blood reacts with chemicals on the strip and the blood glucose meter receives an electronic pulse. The machine then calculates the amount of glucose in the blood and displays glucose reading on the digital screen. A record of the readings will go a long way in helping the physician decide on the kind of diabetes treatment that needs to be given to the patient.

There is also another way of detecting the abnormal or normal blood glucose level in the body. Here, the drop of blood is placed on a special strip that changes color, depending on the amount of glucose. There is a color-coded index that comes along with it that will have listed the particular color the strip changes into when it reacts with the blood and judges the amount of glucose in it. There will be different colors for different amount of glucose. However glucose reading is not very accurate, as it does not give you the exact amount of glucose present.

A blood glucose monitor gives fairly accurate readings if used properly. The glucose meter has to be maintained. It may become old and dirty and if it is kept at high temperature or humidity, the machine's glucose reading may become inaccurate. It must be cleaned with a slightly damp cloth every now and then, to keep it dirt free. The hand from which the blood is taken must be clean and dry. Otherwise, the dirt may interfere with the glucose test results.

This glucose test will help people keep track of the glucose level in their blood and control their normal blood glucose levels and continue their diabetes treatment effectively. They will be help patients to make dietary changes and adjust their consumption of fat and carbohydrates. This will help them maintain normal blood glucose level and undertake any glucose treatment if necessary.

How an Air Conditioner Works


Here is how an air conditioner cools; a window air conditioner has a cooling system which has four main parts or components: the compressor, condenser, evaporator, and a metering device. An air conditioner actually removes the warmness from the air instead of cooling it. The compressor is the motor of the system; it is located in the middle of the air conditioner. It is black and roughly the size of a football; the compressor runs when the appliance is on the cool setting, and the thermostat is set for a colder temperature. When the compressor is running it actually compresses the refrigerant gas from a low to a high pressure. The high pressured gas is cooled so it turns to a liquid, and then it is brought to the condenser.

The condenser is a group of tubes with fins attached, sort of like a radiator. The condenser is located on the back of the unit; it looks like silvery fins. When the refrigerant is a liquid it gives off heat, the heat is drawn away from the refrigerant tubes by those silvery fins. When the liquid refrigerant has gone through the tubes, it goes through another small copper tube (the capillary tube), also known as the metering device. This tube is connected from the end of the condenser to the beginning of the evaporator.

Now, the evaporator is on the front of the air conditioner, this part also has silver fins. Once the liquid refrigerant exits the capillary tube it is inserted into the big evaporator tubes. When that liquid refrigerant enters the evaporator tubes it expands back into a gas, this gas absorbs heat. Then the refrigerant gas goes through the evaporator tubes and ends up back in the compressor. The evaporator is cold to the touch because it is absorbing heat. This sudden drop in temperature causes any humidity to be collected on the evaporator. There is a fan in the unit that circulates the air for the condenser coils and the evaporator.

The metering device is a little tube in between the end of the condenser and the evaporator inlet. Sometimes, on larger size air conditioners this can be a type of valve that open and close depending on the temperature of the outlet of the cooling coil, which makes sure there is a proper flow of refrigerant to the coil.

If the air conditioner is running, the fan and compressor both are running. The fan motor has two fan blades connected to it on either end. The fan blade on the inner part of the appliance draws the air in the room over the cold evaporator coils. The fan blade located on the outer part of the air conditioner draws the outside air over the warm condenser coils. Since the evaporator coils are cool they cause any moisture in the room to collect on them. When there is a good amount of moisture on them it will drop off the coils and into the bottom pan of the air conditioner.

The thermostat works by reading the air temperature coming into the appliance. When the air entering the unit reaches a set temperature it will make the compressor turn off. Sometimes the blower will still blow, depending on the selection made on the control panel. Digital thermostats work in basically the same way, but they tell you a more accurate temperature readout.

The selector switches in an air conditioner let you choose the fan speed. The compressor will always run at the same speed no matter what the settings are. If you choose a "low cool" setting, the fan will run at a slower speed but the compressor will still run with the same cooling capacity. There are also other switches to control different features on some air conditioners.

Well, I hope this article has helped you learn how your household window air conditioner works.

How An Evaporative Air Cooler Or Swamp Cooler Works


A portable evaporative air cooler, or swamp cooler, is a great alternative for inexpensive cooling. These are both less expensive to purchase and less expensive to run than a portable air conditioner. Also, the mechanism is much less complex than an air conditioner, so it will require less maintenance and upkeep.

An evaporative air cooler operates on the principle of an endothermic reaction. An endothermic reaction is a process that absorbs energy in the form of heat. The evaporative air cooler passes air through a wet media (wick). As the air passes through the water in the wick evaporates and the reaction causes heat in the air to be absorbed.

This may not be so simple to understand, but the process is one that we experience every time we sweat. On a hot day, sweat evaporates off of your skin causing the same endothermic reaction as an evaporative air cooler does. Another example is getting out of a swimming pool on a breezy and hot day. Even though the temperature may be over one hundred degrees, the water rapidly evaporating off of your body may make you feel chilled or cold. A traditional air conditioner uses a liquid like Freon to absorb the heat. It then dumps the heat outside of the area being cooled through venting. An evaporative air cooler instead cools the air by using the endothermic reaction described.

Evaporative air coolers are better suited for dry climates. More water can be evaporated in dry air than in humid air, making these much more effective when humidity is low. Also, unlike when using a traditional air conditioner, the area being cooled should not be sealed up. The area should be ventilated so the humid air produced by the cooler can be carried away and replaced by drier air.

Since a swamp cooler consumes water, a sufficient water tank size should be considered. The rate at which an evaporative air cooler consumes water is around half a liter an hour depending on the humidity level, so a six to ten liter tank is recommended. An evaporative air cooler should have an air flow of at least 500 cubic meters per hour. Brands, such as the SPT evaporative air cooler cooler may offer other features such an ionizer or ice packs. These additional features add some cost, but prices for a portable evaporative air cooler is always lower than an equivalent portable air conditioner. Plus, they are cheaper to run and maintain.
