“…Echocardiographic measurement of IVC diameter along with its collapsibility has been used as an estimation of RA pressure 38 and intravascular volume status. 39 The decrease of IVC collapsibility has been described in patients with acute PE in relation to increased RA pressure. 40 However, we also found that IVC collapsibility in those patients not on mechanical ventilation is a prognostic parameter in PE, which likely reflects the negative impact of elevated RA pressure in these patients.…”

“…1) is being increasingly recognized as potential replacement or at least an attractive adjunctive modality to traditional methods [4,40,41]. This index measures the fractional change in major venous diameters through the respiratory cycle rather than relying on a single measurement of venous diameter [6,15,42,43]. This, in turn, provides internal "standardization" of vessel diameter-derived hemodynamic information.…”

“…Among more recent developments for VCI, the most significant findings include the demonstration that the subclavian vein collapsibility (SCV-CI) fairly well approximates the inferior vena cava collapsibility (IVC-CI) [43]. This, in turn, provides alternative options for estimating VCI when the "gold standard" IVC-CI is unobtainable (i.e., due to patient factors such as morbid obesity or surgical dressings).…”

“…Although a learning curve is clearly present for both SCV-CI and IVC-CI, the difficulty of these bedside assessments is not prohibitive. In addition to providing a potential alternative to IVC-CI, the subclavian vein-based assessment takes less time than the vena cava assessment according to one preliminary study [43].…”

Accurate hemodynamic and intravascular volume status assessment is essential in the diagnostic and therapeutic management of critically ill patients. Over the last two decades, a number of technological advances were translated into a variety of minimally invasive or non-invasive hemodynamic monitoring modalities. Despite the promise of less invasive technologies, the quality, reliability, reproducibility, and generalizability of resultant hemodynamic and intravascular volume status data have been lacking. Since its formal introduction, ultrasound technology has provided the medical community with a more standardized, higher quality, broadly applicable, and reproducible method of accomplishing the above-mentioned objectives. With the advent of portable, hand-carried devices, the importance of sonography in hemodynamic and volume status assessment became clear. From basic venous collapsibility and global cardiac assessment to more complex tasks such as the assessment of cardiac flow and tissue Doppler signals, the number of real-life indications for sonology continues to increase. This review will provide an outline of the essential ultrasound applications in hemodynamic and volume status assessment, focusing on evidence-based uses and indications.

“…Its role in the CAVEAT examination is best directed to identification of hypovolemia (implying hemorrhage). The examination of the inferior vena cava (or other central veins) can be quickly performed, usually requiring <5 min [19][20][21][22]. The central venous assessment can be either qualitative or quantitative.…”

Ultrasound technology has become ubiquitous in modern medicine. Its applications span the assessment of life-threatening trauma or hemodynamic conditions, to elective procedures such as image-guided peripheral nerve blocks. Sonographers have utilized ultrasound techniques in the pre-hospital setting, emergency departments, operating rooms, intensive care units, outpatient clinics, as well as during mass casualty and disaster management. Currently available ultrasound devices are more affordable, portable, and feature user-friendly interfaces, making them well suited for use in the demanding situation of a mass casualty incident (MCI) or disaster triage. We have reviewed the existing literature regarding the application of sonology in MCI and disaster scenarios, focusing on the most promising and practical ultrasound-based paradigms applicable in these settings.
