The goal of this interventional study is to asses echocardiographic variations in emergency department's elderly patients receiving red blood cell transfusion. The main questions it aims to answer are : * is there a modification of echocardiographic parameters after red blood cell transfusion ? * which parameter is the most impacted by red blood cell transfusion ? Participants will have a transthoracic echocardiography before, just after and 15 minutes after red blood cell transfusion.

RECRUITINGE/A ratio modification
E/A ratio permits to estimate left ventricle pressure
Time frame: Base line, just after and 15 minutes after red blood cell transfusion
E/e' ratio modification
E/e' assesses left ventricle diastolic function
Time frame: Base line, just after and 15 minutes after red blood cell transfusion
E wave deceleration time
E wave deceleration time is a reflect of left atrium pressures
Time frame: Base line, just after and 15 minutes after red blood cell transfusion
Velocity-time Integral (VTI) modification
Aortic velocity-time integral is the reflect of cardiac output
Time frame: Base line, just after and 15 minutes after red blood cell transfusion
Lung score modification
Lung score permits to asses if extravascular water is present in lungs
Time frame: Base line, just after and 15 minutes after red blood cell transfusion
New York Heart Association scale (NYHA) modification
NYHA is a validated scale to asses patient dyspnea
Time frame: baseline and 24 hour after red blood cells transfusion
