#165 Fluid Assessment in Critical Care | CVP, PPV, PLR, and IVC Ultrasound Explained

How do you assess fluid status at the bedside? In this episode, we break down the four main fluid assessment strategies used in emergency and critical care: 🔹 Central Venous Pressure (CVP) – static, trend-based but poor predictor of fluid responsiveness 🔹 Pulse Pressure Variation (PPV) – dynamic and strong evidence in the right conditions 🔹 Passive Leg Raise (PLR) – safe, reversible preload challenge valid across rhythms and ventilation 🔹 Inferior Vena Cava (IVC) Ultrasound – quick, non-invasive, helpful in extremes of volume status

#164 IVC Ultrasound Assessment Explained | Fluid Status & Volume Responsiveness Emergency Critical Care

Inferior Vena Cava (IVC) ultrasound is a simple, fast, and non-invasive bedside tool for estimating volume status and fluid responsiveness. By assessing the IVC diameter and its respiratory variation, clinicians can better guide resuscitation — especially in shock or critically ill patients.

#163 Passive Leg Raise (PLR) Explained | Fluid Responsiveness & Bedside Tips

The Passive Leg Raise (PLR) test is one of the most reliable and safest ways to assess fluid responsiveness at the bedside — without giving unnecessary IV fluids. By mobilizing ~300–500 mL of venous blood centrally, PLR provides a reversible preload challenge that can guide resuscitation in critically ill patients.

#162 Pulse Pressure Variation (PPV) Explained | Fluid Responsiveness & Bedside Tips

Pulse Pressure Variation (PPV) is one of the most reliable bedside tools for assessing fluid responsiveness in mechanically ventilated ICU patients. Unlike static measures such as CVP, PPV uses arterial waveform analysis to predict whether a patient will benefit from fluids.
