What this trial studies

This observational study enrolls patients at the University of Louisville's Emergency Department who are experiencing acute respiratory failure. Participants will undergo standard pulmonary point-of-care ultrasound (POCUS) and AI-assisted lung auscultation using an Eko CORE stethoscope to evaluate the effectiveness of the AI tool in diagnosing their condition. The study aims to compare the accuracy of these two diagnostic methods by analyzing the final discharge diagnosis as the ground truth. Both examinations will be performed by the same examiner, ensuring consistency in the assessment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older presenting with new onset shortness of breath and an increasing need for oxygen therapy.

Not a fit: Patients with trauma or pneumothorax as the cause of their acute respiratory failure may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of diagnosing acute respiratory failure, leading to better patient outcomes.

How similar studies have performed: Other studies have shown promise in using AI for diagnostic purposes, suggesting potential success for this approach.
