The IVC has long been used to estimate "volume status." Multiple studies have demonstrated that it performs poorly.

The Venous Excess Ultrasound (VExUS) score was developed as a more accurate alternative — and it predicts outcomes that the IVC alone cannot.

Portal vein pulsatility fraction >30% — a marker of elevated right atrial pressure — is independently associated with higher rehospitalization and death rates compared to patients discharged with normal portal vein flow.

To learn how to scan the heart and estimate the left ventricular ejection fraction accurately, get a copy of The POCUS Textbook:

[POCUS Med Ed @pocusmeded]

In the POCUS era, estimating a patient's ejection fraction at the bedside feels trivial. Yet, most clinicians are not trained in POCUS and continue to rely on auscultation.

Cardiologists are among the most highly trained auscultators in medicine. Yet in a blinded study comparing a stethoscope to POCUS, they correctly identified only 35% of patients with reduced left ventricular ejection fraction.

POCUS identified 96%.

[POCUS Med Ed @pocusmeded]

Qualitative LVEF estimation with POCUS is more practical at the bedside than a precisely calculated value. A normal EF (55–70%) is visible as walls contracting to reduce cavity size by roughly half or more. Walls that barely move or nearly touch at end-systole are the two extremes.

Clearly, Google Omni has been wildly underrated.

Here it's turning a normal human hand into a live anatomy demo! Letting you see the muscles, tendons, and cartilage as if the skin were removed.

Brilliant for educational purposes!

A genius distraction tactic. Thank you so much @doctorsydney_dvm for sharing!

CT pulmonary angiography exposes patients to significant ionizing radiation, IV contrast, and cost. In more than half of the cases ordered for suspected PE, it finds something other than a PE.

Multi-organ POCUS of the lungs, heart, and lower extremities can change this.

[POCUS Med Ed @pocusmeded]

In a prospective study of 357 Italian ED patients, multi-organ POCUS (lung + cardiac + DVT) was compared to high-sensitivity CT angiography.

PE was diagnosed in 110 (30.8%) out of 357 enrolled patients. Multiorgan POCUS yielded a sensitivity of 90% and a specificity of 86.2%.

No patients with negative multiorgan POCUS and a negative D-dimer had a PE!
