What Is Pulse Pressure Variation (PPV)? - Cardiology Community

Описание: What Is Pulse Pressure Variation (PPV)? In this informative video, we will discuss Pulse Pressure Variation (PPV) and its significance in assessing heart function during mechanical ventilation. PPV is a dynamic measurement that captures changes in arterial pulse pressure throughout the breathing cycle, providing valuable information for healthcare professionals, especially in critical care settings. We will explain how PPV is calculated and what the results can indicate about a patient’s response to fluid administration.

Additionally, we will cover the essential conditions for accurately measuring PPV, including the importance of controlled mechanical ventilation and the absence of spontaneous breaths. Factors that can influence PPV values, such as tidal volume and heart rate to respiratory rate ratio, will also be addressed.

Understanding PPV can significantly impact patient management during procedures like cardiac catheterization and angiography, allowing for real-time assessment of fluid responsiveness. This knowledge is vital for cardiologists aiming to optimize patient care and improve outcomes.
