What are the orthostatic vital symptoms?

orthostatic vital features, also called tilting or postural vital symptoms, measure blood pressure and pulse frequency, while patients sit, stand or position on the back, lies up. The results of these measurements are used to assess the possible exhaustion of volume, such as blood loss, vomiting or diarrhea. Doctors use results to determine whether patients need further testing, intravenous substitution therapy of fluids or other forms of treatment. First, patients go to the back position for one to three minutes before blood pressure and pulse readings. Patients who do not feel dizziness and are able to walk alone can skip the seating measurements and move directly to the position. Those who are brought to a medical facility by an ambulance or a wheelchair or those suffering from dizziness are placed in a supported position for the second reading. In order to ensure an accurate comparison, orthostatic vital symptoms on the same shoulder must be brought during both measurements.

Usually, when the patient stands out of the position on his back, gravity causes blood to join in the lower body, triggering a reaction in the heart receptors. This reaction causes blood vessels to limit the blood vessels, heart rate increases and the kidneys stick to fluids. These actions force blood back to the basic system that provides the circulation of the vital organ such as heart, liver, kidneys and brains. In patients with reduced blood volume, the circulatory system does not have enough blood to create this reaction.

Experts are in disagreement at what exactly represents a significant change in orthostatic vital slices from lying down to a sitting or standing position. The general consensus states that a pulse increases greater than 20 rhythms per minute or a drop in blood pressure greater than 20 millimeters of mercury (mm Hg) may indicate a deserted volume of fluids. Doctors usually deal more with diastolic blood pressure, which represents the lower issueWhen reading blood pressure, which measures pressure when the heart is at rest.

Conditions that may cause fluid volume loss include a recent brain attack such as stroke or aneurism, toxic shock syndrome, alcohol mining, autonomous disorders and chronic fatigue syndrome. Prolonged rest of the bed, diabetes and neurological diseases can also exhaust the volume of body fluid. Some medicines may also be responsible for the condition, including diuretics, calcium channel blockers and monoamine oxidase inhibitors (MAO).

While orthostatic vital symptoms can be a useful tool to help diagnose volume exhaustion, it is usually monitored with further testing. Many factors affect blood pressure and pulse speed, so that reliable indicators of a particular problem in themselves.
