Role of Blood Pressure Monitors
What is blood pressure?
Blood pressure (BP) is the force per unit area exerted on the blood vessel walls by the blood as it flows through them.
It is usually measured at the wrist as this helps track the pressure of blood in the brachial artery which is the major artery leading away from the heart in the upper right and left arms. The pressure can also be measured at the ankle.
The blood pressure measurement consists of a higher and a lower reading. These are known as the Systolic and Diastolic readings. This are usually measured in mmHg (mercury column height in mm). It is shown as a systolic/diastolic reading. As an example, 118/70 means 118mmHg Systolic and 70mmHG Diastolic.
These readings can be categorized as
1. 120/80 is 'Normal'.
2. 120-139 Systolic or 80-89 Diastolic is considered as 'Prehypertension'.
3. 140 or over Systolic or 90 or over Diastolic is considered as Elevated.
BP is checked by doctors usually by using an instrument called a sphygmomanometer. Blood pressure monitors are also available at various pharmacies for checking the pressure easily at home. These come with a digital display which makes it easy to read the values accurately.
The process for taking a reading is simple and involves the following steps.
1. Wrap the arm cuff or wrist cuff as the case may be, provided with the blood pressure monitor.
2. Pump the cuff with air through a hand bulb. This slowly squeezes the arm or wrist till it temporarily interrupts the flow of blood. The pressure gauge reaches its peak.
3. As the pressure starts to drop, mark the pressure where the pulse is first heard. This is the systolic reading.
4. As the pressure continues to drop, monitor the pulse till the last audible beat at take pressure reading. This is the diastolic reading.
For a greater reliability in the BP readings the following precautions are helpful.
1. Taking multiple readings and then the averaging these, will give to a more accurate final result.
2. Making sure there is a gap of atleast 2 minutes between readings.
3. Avoiding caffeinated beverages, smoking for atleast half an hour before the readings.
4. Being relaxed before taking the readings.
Most modern blood pressure monitors are quite accurate in taking blood pressure readings. This can be backed by a regular visit to your doctor every 2-3 months.
High blood pressure is a symptomless ailment and in a number of cases, the person is not even aware of this situation. It leads to a greater risk of future problems related to the cardiovascular system and a regular checkup is essential.

Using Garlic To Lower Your Blood Pressure - Does This Really Work?
Does garlic really lower blood pressure? Some say yes. In fact, there are studies showing blood pressure can be affected positively by adding garlic to the daily diet. Does this mean garlic is as effective as blood pressure lowering medicine? This article examines this question and more about garlic and blood pressure.
There is no substitute for your doctor's advice. All cases of hypertension cannot be treated exactly the same way. This is because no two people are the same. Some people tolerate some medications better than others and no two hypertension sufferers have the same exact readings. Treatments for high blood pressure may vary between different age groups. They also may vary depending upon which gender the patient is. Because of these facts, you should follow your doctor's orders to a tee.
Many times a person will find he has mild or borderline hypertension. In this case, the doctor may send the patient home and tell him to watch his diet. Then another appointment will be made to check the BP reading again in a few weeks.
In a situation like this, this person should cut some of the fats out of the diet and replace them with high fiber foods. If the doctor has approved it, the patient should also add some exercises to his weekly routine. Also, since getting an ample amount of vitamin D is healthy for those who are trying to control their blood pressure, a little fresh air and sunshine would be advisable.
Of course, person trying to control their BP should avoid table salt. They should start eating foods high in magnesium and potassium, such as beans, which neutralize salt in the system. Once these changes are being made, it may also be helpful to add a little garlic to the diet. One fresh clove of garlic per day is the recommendation. Fresh is a key word because garlic loses some of its stuff when it is cooked. Also, there is some controversy as to whether or not garlic supplements are helpful, so using fresh garlic is a better bet.
Garlic can be minced for the simple reason it would probably be impossible to eat a whole clove of garlic. However, a finely chopped clove of garlic could be sprinkled on any dish. Over the course of three meals the clove of garlic would hardly be noticed.
As you might imagine, going against doctor's orders, eating the wrong things, covering all your foods with salt and going on a drinking binge will render any hypertension treatment ineffective. However, if you are following a plan conducive to lowering your blood pressure, adding a clove of garlic a day can be just what you need to get your reading back to perfection.
