Some people experience high BP only when they visit the doctor's office. This condition is called "white-coat hypertension." If your doctor suspects this, you may be asked to monitor your BP at home or asked to wear a device called an ambulatory BP monitor. This device is usually worn for 24 hours and can take BP every 30 minutes. In this section you will learn more about diagnosing high blood pressure.
You can find out if you have high BP by having your BP checked regularly. Most doctors will diagnose a person with high blood pressure on the basis of two or more readings, taken on several occasions. A consistent BP reading of 140/90 mmHg or higher is considered high blood pressure, another term for hypertension.
High blood pressure often has no signs or symptoms. The only way to find out if you have high blood pressure is to be tested for it. Using Blood pressure monitor, your doctor or nurse can diagnose, if your blood pressure is high.
To test your blood pressure, your doctor will use a familiar device with a long name. and may look something like this: Some blood pressure testing devices use electronic instruments or digital readouts. In these cases, the blood pressure reading appears on a small screen or is signaled in beeps, and no stethoscope is most accurate blood pressure monitors are mercurial monitors then the Aneroid type.These both needs stethoscope and a nurse and a doctor to diagnose the option is not viable for homecare use ,hence the need of digital homecare BP Monitors .In the digital type, there are basically 2 models,
1.Wrist type - less accurate
2.Upper arm- more accurate
A blood pressure level of 140/90 mmHg or higher is considered high. About two-thirds of people over age 65 have high blood pressure. If your BP is between 120/80 mmHg and 139/89 mmHg, then you have prehypertension. This means that you don't have high blood pressure now but are likely to develop it in the future.
Low blood pressure can be caused by low blood volume, hormonal changes, widening of medicine side effects, anemia, heart problems or endocrine problems.Reduced hypovolemia, is the most common cause of hypotension. This can result from hemorrhage; insufficient fluid intake, as in starvation; or excessive fluid losses from diarrhea or vomiting. Hypovolemia is often induced by excessive use of diuretics.
Some heart conditions can lead to low blood pressure, including extremely low heart rate (bradycardia), heart valve problems, heart attack and heart failure. These conditions may cause low BP because they prevent the body from being able to circulate enough blood.
Meditation, yoga, or other mental-physiological disciplines may produce hypotensive effects.Diagnosis For most adults, the healthiest blood pressure is at or below 120/80 mmHg. A small drop in BP, even as little as 20 mmHg, can result in transient hypotension.
The treatment for hypotension depends on its cause. Chronic hypotension rarely exists as more than a symptom. Asymptomatic hypotension in healthy people usually does not require treatment. Adding electrolytes to a diet can relieve symptoms of mild hypotension. In mild cases, where the patient is still responsive, laying the person in dorsal decubitus (lying on the back) position and lifting the legs will increase venous return, thus making more blood available to critical organs at the chest and head. The treatment of hypotensive shock always follows the first four following steps. Outcomes, in terms of mortality, are directly linked to the speed in which hypotension is corrected. In parentheses are the still debated methods for achieving, and benchmarks for evaluating, progress in correcting hypotension. A study on septic shock provided the delineation of these general principles. However, since it focuses on hypotension due to infection, it is not applicable to all forms of severe hypotension.
