The Systolic is Lying Why the Diastolic Shock Ind

Описание: Is the Systolic Blood Pressure lying to you? In critical care, we often fixate on the top number, but the real story of vascular tone and coronary perfusion is hidden in the Diastolic.In this session of Pulse and Pressors, we break down the Diastolic Shock Index (DSI)—an emerging, high-yield adjunct that helps you identify vasoplegia before the MAP collapses. If you are managing septic shock, understanding the DSI is the difference between "filling a tank" and "tightening the pipes."In this lesson, you will master:✅ The DSI Formula: Why HR/DBP is a superior marker for distributive shock.✅ The Coronary Connection: How low diastolic pressure starves the left ventricle.✅ The 2.0 Threshold: When to pivot from fluid resuscitation to early vasopressors.✅ Tone vs. Volume: Using the DSI as a clinical green light for "tighteners."Timestamps:0:00 The Systolic Illusion1:15 The Coronary Perfusion Mental Model2:30 Calculating the DSI ($HR / DBP$)3:45 The "Locksmith" Strategy: Tone over Volume4:30 The Pulse and Pressors PearlDisclaimer: The DSI is an emerging clinical adjunct.
