The Pulsatility Index Calculator can be used to calculate the Pulsatility Index (PI), a hemodynamic parameter that assesses blood flow characteristics in various vascular beds.
Learn how to use the Pulsatility Index Calculator calculator and its working principles
The Pulsatility Index (PI) is a hemodynamic parameter used in ultrasound to assess blood flow characteristics. It is calculated as the difference between the peak systolic velocity and the end-diastolic velocity. A higher PI indicates stiffer arterial compliance and higher pulsatility, while a lower PI suggests more compliant arteries.
The PI is commonly used in the assessment of vascular health, particularly in conditions such as peripheral artery disease, renal artery stenosis, and other vascular disorders. It helps in evaluating the severity of the condition and monitoring treatment effectiveness.
