Background summary
Echocardiography is the primary imaging modality for diagnosing cardiac conditions especially in point of care treatment (POCT).1 Over the past two decades, technological advancements have resulted in the emergence of miniaturized handheld ultrasound equipment that is compact and battery operated. The simplicity of use, availability at the patient’s bedside, easy transportability, and relatively low cost have encouraged physicians to use these hand held echocardiography (HHE) devices for prompt medical decision making in POCT.23–5 As a consequence, the use of HHE is on the rise even among non-echocardiographers (intensivists, emergency care physicians).6 However, bedside quantification of cardiac output (CO), stroke volume (SV) and left ventricular ejection fraction (LVEF) with such devices is yet impossible and needs to be performed offline at the office. Evaluating the cardiac function can play a highly valuable role in POCT for patients in cardiac distress or to check the volume status of a patient.7–10 By incorporating an automated quantification tool (DIA app) in a commercially and clinically available HHE device (Lumify, Philips), bedside measurements of CO, SV and LVEF are among the possibilities. In this observational study we want to evaluate the performance of the Lumify/DIA system and assess its accuracy in quantifying CO, SV and LVEF compared to conventional offline methods. It is hypothesized that measurement of CO, SV and LVEF with the Lumify/DIA system corresponds with CO, SV and LVEF measurements with conventional non-automated echocardiography. With the Lumify/DIA system we are striving for improvement of our daily cardiac POC assessment.
Study objective
It is hypothesized that measurement of CO, SV and LVEF with the Lumify/DIA system corresponds with CO, SV and LVEF measurements with conventional non-automated echocardiography.
