Feasibility of measuring echocardiographic parameters in critically ill patients with coronavirus-19 sepsis. VAC, ventricular-arterial coupling; EF, LV ejection fraction in %; IVC, maximal diameter of inferior vena cava in mm; SVR, systemic vascular resistance in mmHg L−1 min; ME, LV end-systolic maximal elastance in mmHg mL−1; AE, end-systolic arterial elastance in mmHg mL−1; sm, tissue Doppler peak systolic wave at lateral mitral annulus in cm s−1; Ee, ratio of early pulsed-wave Doppler to early tissue Doppler diastolic wave velocity at the lateral mitral valve annulus; st, tissue Doppler peak systolic wave at tricuspid lateral annulus in cm s−1; TAPSE, tricuspid annulus plane systolic excursion in mm; EA, ratio of early to late diastolic wave velocity at the mitral valve; AS, absolute values of global LV longitudinal peak systolic strain in %; PCD, pulmonary circulatory dysfunction
