Fluid responsiveness is arguably one of the most controversial, error-prone applications of ultrasound. It’s a complicated topic that - spoiler - involves a lot more than just the IVC! Learn to avoid common pitfalls, and how to integrate multi-organ assessment into your clinical assessment to guide treatment plans.
Integrated IVC/lung scan for fluid responsiveness
The guys at the Ultrasound podcast outline an integrated approach to fluid responsiveness.
Cardiac output Determination
This 20-minute video from our own Dr. Katie Wiskar covers the physiology, rationale, and technique for using cardiac POCUS to estimate stroke volume and cardiac output by measuring LVOT VTI. This skill is invaluable to anyone caring for acutely unwell patients in shock!
Note: typo in the video at 00:45 in DO2 equation. Should read:
DO2 = Q x [(Hb x SaO2 x 1.34) + (PaO2 + 0.003)]
Carotid Doppler VTI for fluid responsiveness
Learn about this novel application of carotid POCUS from Irene Ma’s MGH video tutorial
