What Is Low Blood Pressure
Low blood pressure is difficult to find a provider of clinical health care to address. When the high blood pressure known as the “silent killer” because it is associated with more severe symptoms, hypotension (hypo = low + stress = pressure) May be normal for the patient, if there are no symptoms, but can be of great importance if it is associated with reduced function of organs. Sometimes less is better, May be the goal to achieve in keeping blood pressure under control. Sometimes it is less bad, because there is not enough pressure to ensure blood flow to the organs of the body. Low blood pressure can be a problem and needs to be a symptom associated with this small number. Readings below 120/80 May be normal, depending on the clinical situation. Many people have systolic blood pressure below 100, but some people develop symptoms, the pressure is low. Symptoms appear low blood pressure, because one or more organs in the body is not getting enough blood. The low blood pressure is normal for the patient, then there will be no symptoms. The low blood pressure is symptomatic, then the patient May feel dizzy, dizziness and weakness, shortness of breath or chest pain. Symptoms will depend on which organ in the body is not enough blood flow.
Blood pressure in two parts and expressed as a ratio. “Normal” blood pressure, for example, 120/80 (120 over 80) and measured pressure in the arteries of the body. Systolic pressure, the top number, measures the pressure in the arteries when the heart is contracting (systole) to pump blood to the body. Diastole pressure, fewer steps, resting pressure within the arteries when the heart is idle. Normal blood pressure depends on many factors, including age and body size. Infants and children have lower than normal reading adults. Petite small or patients May have a lower blood pressure normal ranges. According to the American Heart Association guidelines, any reading over 120/80 are considered pre-hypertension or early high blood pressure. You think the heart and blood vessels (arteries and veins) as a blood pump system, and pump oil in your car. The oil is pumped through the rigid tube. The pressure remains relatively constant during the pumping cycle of the pump, unless it fails or is an oil leak.
Then the pressure drop of oil. The body is similar, except that the flexible pipe walls, which means that the space in the arteries can get bigger or smaller. If the space gets bigger, there is less efficient and liquid pressure drops. If space becomes smaller, the pressure goes up. Arteries have multiple layers of muscle in their walls that can contract and narrow the arteries, which makes up less space in the inbox. As an alternative, you can relax the muscles and the arteries to expand as more space. These muscles are controlled by the autonomic nervous system, an automatic system of the body, the correction for the moment to moment changes in the organism’s relationship to the world. The autonomic nervous system has two paths that balance each other. Since the sympathetic nervous system uses the adrenaline (epinephrine) that causes muscles to contract (sympathetic tone). Nerves that help control this in the sympathetic trunk, which is a group of nerves that runs along the spine. The parasympathetic system uses acetylcholine muscles in the walls of blood vessels to relax the vagus nerve. For example, when I got up, blood vessels narrow little cause a slight increase in blood pressure, so that they can travel to the blood to the brain.
Without these changes, May you feel dizzy or faint. The low blood pressure causes the clinical symptoms, the cause will be one of the three main categories. Or heart is not pumping enough pressure, artery walls are too extensive or insufficient intravascular fluid (within + vascular = blood vessels) within the system. Heart of the electric pump. Problems or with a pump or electricity can cause problems with low blood pressure. Heart valves allow blood to flow in one direction only. If the valves fail, blood can restore, minimize the amount that will flow to the body. If the valve becomes narrowed (stenotic), then blood flow can be reduced. Both situations can cause hypotension. If too fast heart rate, blood pressure fall, because May does not have enough time to load between each heartbeat (diastole). If the heart beats too slowly, May have too much time spent in diastole, when blood is not flowing.
If the heart muscle is damaged or irritated, they can not have enough energy for pumping to maintain blood pressure. In a heart attack (myocardial infarction), heart muscle sufficiently May be stunned, so that the heart too weak to pump effectively. Diuretic drugs [eg, hydrochlorothiazide (Hydrodiuril), furosemide (lasix)] is used to control blood pressure by causing the kidneys to make more urine and reduce intravascular volume. If the patient loses too much water and become dehydrated, low blood pressure May result. Beta-blockers and calcium channel blockers are the two most commonly prescribed drugs used to treat high blood pressure. They can cause the heart to beat too slowly and thus cause hypotension. Every heart medications should be monitored by the health care provider to assess the reaction of the organism and how to choose the appropriate dose. Drugs such as sildenafil (Viagra) in combination with nitroglycerin May lead to dilatation of blood vessels and reduces blood pressure.
Normal physiological changes during pregnancy increase the intravascular space, especially during the first two quarters, and May cause low blood pressure. One of the complications of diabetes is nerve damage in the body, including those on the autonomic nervous system. The team of people with diabetes who have autonomic dysfunction, orthostatic hypotension May occur. Blood vessels are not able to adapt to rapid changes in positional. The low blood pressure caused by lack of blood flow to organs of the body, then the body will begin to fail. This can lead to stroke, heart attack, kidney failure and bowel ischemia (reduced blood supply in small and large intestine). Shock and death are the end result of prolonged low blood pressure.
