Sphygmotensiograph: Pulse voltage measurement

A sphygmotensiograph is a medical device that is used to measure and record a patient's pulse pressure. The word "sphygmotensiograph" comes from the Greek "σφυγμός" (sphygmo), which means "pulse", the Latin "tensio", which translates as "tension", and the Greek "γράφω" (grapho), which means "to write" or "to depict" . Thus, sphygmotensiograph literally means "pulse tension image."

Pulse pressure is an important indicator of cardiovascular health and is used to diagnose various conditions and diseases. A sphygmotensiograph measures the pressure created by the arteries with each heartbeat and records it in a graph called a sphygmogram.

The principle of operation of the sphygmotensiograph is based on the use of a cuff, which is placed on the patient at the level of the shoulder or wrist. The cuff is filled with air, and a special sensor or pressure gauge is used to measure the pressure in the arteries. With each heartbeat, the pressure in the arteries changes, and these changes are recorded by a sphygmotensiograph.

The sphygmotensiograph can be used in clinical practice to assess the state of the patient’s cardiovascular system, diagnose hypertension, atherosclerosis, cardiac arrhythmias and other cardiovascular diseases. It may also be useful in monitoring the effectiveness of treatment and assessing the dynamics of changes in pulse pressure.

Sphygmotensiography is a safe and non-invasive procedure that does not require special preparations or anesthesia. It is highly accurate and allows you to obtain detailed information about the patient's pulse pressure.

In conclusion, a sphygmotensiograph is an important medical device that can measure and record a patient's pulse pressure. It is a useful tool for diagnosing and monitoring cardiovascular diseases. With sphygmotensiography, doctors can obtain valuable information about the condition of a patient's heart and arteries, which helps in making treatment decisions and monitoring its effectiveness.

Sphygmotensiograph

A sphygmotensograph is a device that is used to examine blood vessels and determine their condition. It consists of several sensors that measure the pressure inside the vessels and record the data on a computer.

In the process of work, the sphygmotenograph first establishes the necessary indicators and studies their presence, movement and amplitude. If necessary, this operation can be repeated several times during the day or night to obtain a more accurate picture. The information obtained as a result of the study is recorded in a special journal and allows the doctor to draw conclusions about the patient’s condition. In some cases, the results can be used to predict the risk of developing diseases related to the cardiovascular system.

Introduction When studying blood vessels, it is recommended to carry out measurements in the area of ​​​​the projection of blood vessels, since only such a measurement will provide information about normal biological fluctuations in pressure in the blood vessels. It is of great importance to conduct research under physiological conditions, especially when measuring tension and pulsation of the vessels of the extremities. Therefore, measurements are carried out while the subject is at rest, sitting or lying down, and the latter option seems to be the most appropriate. Also, when inserting the hand, you can notice that some changes and vibration are observed, as well as pulsation of the vessels of the hand. This confirms the need to rest the circulatory system before performing the study. After this, a period of maximum tension in the veins of the limb begins, after some time the pulse decreases, the picture begins to change. But at the same time, the maximum wave of the pulsogram practically does not change. However, this does not mean that the artery of the limb does not pulsate, it is simply not visible visually, at least there are no characteristic movements on the chest. Another important point is the correct placement of the electrodes, which was described above. With the correct location of the electrodes, the results of the study can obtain significantly more information and with greater reliability than with their incorrect location. The next important step is processing the research data, which will be discussed in the next chapter.
