Performance Evaluation of Clinical Ultrasound in Management of Acute Pulmonary Edema in Elderly Patient

Study Overview
=================
Brief Summary
-----------------
The main objective is to assess the validation of the diagnosis early acute pulmonary edema in elderly patients with acute respiratory distress, admitted in a host of vital emergency services by lung ultrasound associated with the measurement of the inferior vena cava.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Intervention lung ultrasound<br>All patients will have strategy with lung ultrasoundlung ultrasound | Device: Strategy with lung ultrasound<br>* Each patient admitted for suspicion of acute lung edema will be treated according to the protocol of the emergency department. Another doctor will independently do a lung ultrasound and measurement of the inferior vena cava. The ultrasound results are not made available to the doctor in charge of the patient. At the end of the study, all the files will be analyzed by a independent committee, blinded ultrasound results for the final diagnosis of acute pulmonary edema.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The result of lung ultrasound associated with the measurement of the inferior vena cava. | Confirm the diagnosis of acute pulmonary edema associated with lung ultrasound to measure the inferior vena cava in patients aged over 65 years in acute respiratory distress, admitted to a service life-threatening emergencies. By checking the results of the ultrasound done by a different doctor from the one who took care of the patient. | 2 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of the proportion of appropriate and inappropriate treatment. | Comparison of specific treatments begun to emergency, as defined by the latest recommendations of Cardiology and Pneumology companies compared to the treatment that would have been given over the results of pulmonary ultrasound. | 2 hours | 
| The duration of the medical care. | The time between the patient support and the final diagnosis. | 2 hours |
