Pulse Wave

A pulse wave is a wave of increased pressure propagating through the aorta and arteries, caused by the ejection of blood from the left ventricle during systole.

The pulse wave occurs as a result of rhythmic contractions of the left ventricle of the heart, which eject blood into the aorta. This flow of pressurized blood creates a wave of increased pressure in the walls of the arteries.

The pulse wave propagates from the aorta along the arterial bed at a speed of 4-10 m/s. As you move away from the heart, the amplitude of the pulse wave decreases due to the expansion of the lumen of the arteries and their branching.

Pulse wave measurements are used to assess the elasticity of the arteries. An increase in the speed of propagation of the pulse wave indicates a decrease in the elasticity of the arterial wall.

Pulse wave is an important diagnostic procedure for assessing the condition of the circulatory system and the general health of the patient.

During the passage of the pulse wave, blood is released from the heart and moves to different parts of the body. When the blood reaches the artery, it enters the capillaries, where gases and other substances are exchanged. At this time, the pressure in the aorta increases, which causes waves to propagate through the arteries. As a result, flashes of light appear on both hands of a person, which are a sign of normal pulsations. These pulsations can be used to determine the speed of blood circulation and identify possible health problems.

The test procedure involves measuring pressure on the wrist of both hands and recording light pulses on one hand. The doctor or healthcare worker measures the pressure within a few seconds and records the data. Then he conducts research and determines the causes of abnormalities in the arterial blood flow.
