Visual Rounds Based on Multiorgan Point-of-Care Ultrasound in the ICU

  Figure 1. Critical care echocardiography imaging. (A) Inferior vena cava diameter. (B) Velocity-time integral of left ventricular outflow tract, which can help to gain cardiac output and fluid responsiveness. (C) Parasternal window parasternal long-axis view. (D) Apical window four-chamber view. (E) Pericardial effusion in subcostal window four-chamber view. (F) Mitral regurgitation in apical window four-chamber view.

  Figure 2. Basic signs of lung ultrasound. (A) A-lines, horizontal reverberation artifacts at a regular distance indicate a high gas–volume ratio below the parietal pleura. (B) Multiple B lines, are vertical artifacts deriving from the pleural line, moving synchronously with lung sliding, usually reaching the bottom of the screen and erasing A-lines. (C) Tissue-like pattern identifies lobar consolidation. (D) Pleural effusion.

  Figure 3. Images of multiorgan ultrasound. (A) Normal doppler tracing of the interlobar vessels in renal ultrasound. The renal resistive index can be measured using the maximal and the minimal arterial velocity during the cardiac cycle. (B) Renal contrast-enhanced ultrasonography. (C) Dilated fluid-filled bowel loops that indicates small bowel obstruction. (D) Blood flow curve of superior mesenteric vein. (E) Optic nerve sheath diameter, which can help to predict intracranial pressure. (F) Cerebral blood flow velocity of middle cerebral artery accessed by transcranial doppler ultrasonography.
