Welcome to Pulse and Pressors, where critical care gets crystal clear.
Stroke Volume (SV) is the true driver of hemodynamics — more sensitive than MAP, more revealing than CVP, and far more actionable than heart rate alone. In this episode, we break down why SV is the earliest indicator of shock, how it reflects preload, afterload, contractility, and heart–lung interactions, and why a 10–15% rise in SV defines fluid responsiveness more accurately than any pressure-based metric.
What you’ll learn:
• The physiology behind SV and why EDV – ESV matters
• How SV responds to ventilation, PEEP, and rhythm changes
• SVV and PPV as predictors of fluid responsiveness
• Why SV-guided resuscitation prevents harm from fluid overload
• Pitfalls: LVOTO, tachycardia, RV failure, and high intrathoracic pressure
• How SV integrates entire hemodynamic physiology into one number
If you want to resuscitate like a top 0.1% critical care expert, mastering stroke volume is non-negotiable.
This is Pulse & Pressors, reflecting on the marvels of the human body.
