Brief Summary

This study assesses the potential of lung ultrasonography to diagnose heart failure.

Conditions

Dyspnea; Cardiac

Keywords

Lung ultrasound; heart failure; diagnosis; accuracy; nurses

Outcome Measures

Primary Outcomes (4)

• the accuracy of LUS performed by nurses in the diagnosis of heart failure

  the accuracy of LUS in the diagnosis of heart failure measured by sensitivity .

  0 days

• the Specificity of LUS by nurses in the diagnosis of heart failure

  the accuracy of LUS in the diagnosis of heart failure measured by specificity.

  0 days

• the reproducibility of LUS in by nurses the diagnosis of heart failure

  the accuracy of LUS in the diagnosis of heart failure measured by area under the roc curve

  0 days

• Agreement between nurses and expert's

  Agreement between nurses and expert's interpretation was assessed by kappa agreement index for ordinal LUS scale classification

  0 days

Study Arms (2)

nurses

ED nurses trained to perform LUS and blinded to the final diagnosis

Diagnostic Test: we perform a lung ultrasound to all the patients admitted for dyspnea independantly from the final diagnosis

emergency physician

certified emergency physician who had accomplished a full mentoring program for "Ultra-Sound Life Support".

Diagnostic Test: we perform a lung ultrasound to all the patients admitted for dyspnea independantly from the final diagnosis

Interventions

we perform a lung ultrasound to all the patients admitted for dyspnea independantly from the final diagnosis DIAGNOSTIC_TEST

Patients were placed in a semi-recumbent or supine position depending on their respiratory tolerance. For each side of the chest, 4 zones have to be assessed : 2 anterior and 2 lateral. The operator should calculate the number of B-lines when present .
