What does pulsatility index mean?

Pulsatile index is an index used to measure the contractility and pumping function of the heart. It is calculated by measuring the pressure and volume of the left ventricle at the end of systole. Generally, the higher the pulse index, the stronger the heart contraction and the better the blood pumping function. In clinical practice, pulse index is often used to judge the condition of patients with heart disease and monitor their postoperative recovery.

The second paragraph: How to measure the pulsation index?

In order to measure the pulsatility index, the left ventricular catheter must be used to measure the pulsatility index while the heart receives the contrast agent. Pressure and volume information during each heartbeat can be recorded by sensors installed at the end of the catheter. According to these data, the pulsation index can be calculated. Although the method of measuring pulse index is very complicated, it is a very accurate method to judge the health status of heart function.

Pulse index is very important for the rehabilitation of patients with heart disease or surgery. By monitoring the change of pulse index, doctors can judge whether there is hypoxia and other abnormal conditions in the heart, so as to take timely measures. In addition, the pulsatility index can also help doctors understand the condition of patients' cardiovascular system. Therefore, the measurement of pulsation index can not only judge the pathological condition of the heart, but also guide the rehabilitation and improve the curative effect.
