The blood pressure symptoms occur, when blood circulates through the arteries of the body, it exerts pressure against the walls of these vessels. This pressure is dependent upon the force with which blood is pumped by the heart. A blood pressure measurement determines the level of that pressure.
Does blood pressure symptoms vary?
Blood pressure symptoms vary during the day and according to activities. Typically, it is lowest during the late night and early morning hours while we are asleep.
Exercise, stress, and many other factors raise blood pressure symptoms. If the blood pressure is consistently too high, it is referred to as high blood pressure
or hypertension. This is a serious condition that can contribute to heart attacks, strokes, and kidney failure.
Hypertension itself causes no symptoms, apart from visual loss and headaches in some severe cases. Therefore, often the only way to know if you have hypertension is by having your blood pressure tested by a doctor or by another health care professional, or by checking it yourself. All adults should have their blood pressure checked at least every three years.
What happens during a blood pressure symptoms measurement?
There are some ways to measure blood pressure. The simplest and most common uses the traditional inflatable cuff attached to a portable device called a sphygmomanometer (pronounced sfig-moe-ma-no-me-ter). This method uses a column of mercury (as in a thermometer) to get a reading. The device measures the amount of pressure needed to raise the mercury, and blood pressure readings are stated in millimeters of mercury, for example, 120/80 millimeters of mercury (abbreviated mm Hg).
The soft cuff is wrapped around the upper arm. (A leg may be used if for some reason an arm is not available.) Air is pumped into the cuff to cut off the flow of blood in the arm for a few seconds. The doctor then places a stethoscope over the major artery located in the crook of the elbow.
The reading at the first sound is the systolic pressure, which represents the amount of force (in millimeters of mercury) when the heart is pumping blood. The second number is the diastolic pressure and represents the amount of strength when the heart is resting between beats.
Some of the newer blood pressure symptoms equipment, designed for those who want to monitor their pressure at home, does not need an external stethoscope and a column of mercury.
Instead, these electronic machines have an automatic listening device built into the cuff, and the readings are displayed on a digital screen. There are also blood pressure symptoms machines that use small bellows which force a needle to move on a dial. These are aneroid (or air) blood pressure recorders.
Recently, portable 24-hour blood pressure devices have been developed. A person is hooked up to an ambulatory monitor. Again, it is a cuff hooked to a small machine (that looks like a small portable radio) that you wear on your belt or carry like a shoulder bag.
Another method, only performed under rare, closely monitored circumstances in the hospital, is to insert a fine needle directly into an artery. This needle is attached to sensors and a recording device.
Does a blood pressure measurement cause discomfort?
No. You will experience some slight pressure on the arm when the cuff is fully inflated, but it is at worst mildly uncomfortable and not at all painful.
How long does a blood pressure measurement take?
Reading takes less than two minutes. As noted earlier, there may be exceptional circumstances in which your doctor might want to know how much your blood pressure changes during an entire day. In this case, a 24-hour blood pressure monitoring device can be used.
When will I get the results?
The reading is immediate and is given as two numbers: the first (higher) number is the systolic pressure (the maximum blood pressure at each heartbeat); the second (lower) number, is the diastolic pressure (the pressure between heart beats). A resting blood pressure of 120/80 mm Hg is ideal for a middle aged adult.
Readings above 140/90 need careful monitoring and may require treating. Hypertension is usually only diagnosed if there are high readings on at least three occasions.
What complications accompany a blood pressure symptoms measurement?
There are no complications from a routine blood pressure measurement.
Preparation of pressure symptoms
Development depends on upon the purpose of the test.
- Not exercise for an hour or two beforehand.
- Not eat a heavy meal for at least an hour beforehand.
- Not have caffeine (coffee, tea, cola, etc.machines) for at least three hours beforehand.
- Not smoke or drink alcohol for at least three hours beforehand.
Blood pressure symptoms warning
Do not rely on the slot machine blood pressure gadgets found in airports and pharmacies for accurate blood pressure measurement devices
These are often poorly calibrated and can yield very misleading results. Frequently, people will stop by one of these machines while on the run or after having a cup of coffee or cigarette – all of which can alter readings.
The results of street-corner or shopping center screening are seldom definitive. Several readings taken at different times are needed for a proper diagnosis to be made.
