Petrova Sample
Petrov's test is a tool that allows you to assess the functionality of the human circulatory system. It was discovered by Russian surgeon Nikolai Nikolaevich Petrov in 1916 and named after him. He described this research method in the journal Surgery in the 20s of the 20th century. Petrov was trying to find a way to measure blood pressure on artery walls. He discovered that when the pressure on the vessels increases, blood begins to move through the arteries, and then through the capillaries, where the exchange of substances between blood and tissues occurs. This process is called cardiac activity. Petrov's test allows you to evaluate the functioning of the circulatory system, as well as diagnose certain diseases, such as hypertension, cardiomyopathy and others.
During the Petrov test procedure, a cuff is placed on the subject's arm, which maintains constant pressure. Then the doctor sharply releases the cuff and records the time during which the pulse occurs. This measures heart rate. Then the blood pressure is measured. To do this, the doctor inserts a catheter into the jugular vein in the neck and listens with a stethoscope. The patient's general health is determined by how quickly his heart rate returns to normal and what his beats per minute are.
Thanks to Petrov's research, it was discovered that there is a connection between cardiovascular disease and a level of blood pressure called hypertension. With increased pressure, the walls of blood vessels are often damaged. The damage can lead to serious consequences, including stroke, myocardial infarction, and various forms of circulatory problems in the brain and limbs. These diseases often lead to disability or death.
