The primary diagnosis means a lot when we talk about any type of illness. It is extremely important to place a correct diagnosis because curing depends on it. Some diseases injure the body unpredictably and with a powerful force. Therefore, there is no time to apply for all possible examinations. On such occasions, doctors prescribe only the most urgent and necessary. And what is a PVR test? The abbreviation means Pulse Volume Recording. Its principle lies in exploring the passage of blood inside the vessels and arteries. The places of observation are legs and arms where the flow is easy to check.
What is a PVR test: usage and benefits
The positive side of a PVR test for legs is the durability of one procedure. Usually, it lasts only 45 minutes, therefore, people can manage their time well. The results come quickly and doctors can make some conclusions that affect the treatment. The mechanism is not harmful or painful, only some discomfort is possible during the operation.
Before choosing a way of diagnostics, doctors take into account the symptoms of patients. Common particularities include:
- Excessive sweating;
- Abnormal heart rate (rapid one, with noise or interruption);
- Lack of strength and fatigue;
- The sense of pain in the area of the chest;
- Dyspnea, dizziness, spinning things around;
- Swelling and shining spots on the body;
- Movement disorders and numbness in legs and arms;
- Sleep problems as a result of constant pain;
- Intense dryness and periodic lameness may temporarily accompany similar shutdowns too.
PVR tests use X-rays for research as a safe source of influence. Radiation doesn’t cause additional troubles. This procedure is secure even for the elderly who suffer from leg artery disease more frequently than the youth. Occupation sometimes predetermines the course of the illness as well. The extra benefit is the absence of side effects after PVR examination, people only feel weakness during a certain period after it.
How doctors provide PVR tests for legs
First of all, specialists ask patients to avoid physical exercise, consumption of alcohol, and smoking a day before the procedure. The reason is that these parameters are able to change some indicators. Doctors don’t demand other preparations for this type of diagnosis.
During PVR tests a patient sits on lies on a special surface. Specialists fasten tools in a place that is not covered with clothes. Applying the gel is an important part of the examination. The next stage is cuffs installation on both legs and arms. A sonographer makes these devices tighter, as a result, patients often hear the sound of their own blood flow. A specialist compares the pressure in extremities, he also calculates the quickness of blood passage. It is possible thanks to the device that transmits information according to sound waves. A computer records these reflected from the cell's waves. Analyzation of the data comes after making some notes. The attending doctor receives the statistics of taken research and predicts further cure.
