Brief Summary

Stroke volume is a major determinant of tissue perfusion and therefore a key parameter to monitor in patients with hemodynamic instability and hypoperfusion. Left Ventricular Outflow Tract (LVOT) Velocity-Time Integral (VTI) measured using pulsed wave Doppler is widely used as an estimation of stroke volume and should be a competence required for every Intensive Care Unit (ICU) physician. Recently, research in Artificial Intelligence (AI) applied to medical imaging constituted a breakthrough in the acquisition of images. The goal of the present study is to characterize and quantify the reliability and reproducibility of LVOT VTI measurements by comparing the measures obtained by minimally-trained operators and expert physicians, guided by UltraSight AI software.

Eligibility Criteria

Inclusion criteria: All patients aged 18 and more Hospitalized in ICU, in whom fluid administration is considered necessary by the clinician in charge, based on the presence of hypoperfusion criterion: * \>10% decrease in mean arterial pressure with respect to baseline value * Skin mottling, oliguria (\<0,5 ml/kg/h) * change in the level of consciousness * hyperlactatemia * decrease in central venous oxygen saturation Affiliation to a French social security system (beneficiary or legal) Participant's or next of kin non-opposition or emergency procedure Exclusion Criteria: Patients with atrial fibrillation, due to the higher variability in LVOT VTI; Patient on Emergency Medical Assistance; Patient under guardianship, curatorship, deprived of liberty.
