This is an observational study that will be enrolling University of Louisville patients who present to the Emergency Department in Acute Respiratory Failure. This study will be to determine if the addition of Eko AI-assisted lung auscultation examination to a standard of care Pulmonary POCUS + assists with acute respiratory failure diagnosis.
Once identified and consented, the subject will undergo both POCUS and AI-assisted lung auscultation using an Eko CORE stethoscope. The POCUS protocol described here is the standard of care for patients who present in acute respiratory failure to the Emergency Room and both groups will receive this standardized care during the study. Upon hospital discharge, the final discharge diagnosis will be used as the ground truth for assessing the accuracy of the POCUS protocol. The POCUS exam and the EkoAI exam may be performed wherever the subject is located in the hospital when first enrolled in the study. If possible, both exams should be performed immediately, in either order. They will be performed by the same examiner. Both the POCUS and the EkoAI exam will be analysed by an investigator blinded to the final diagnosis.

RECRUITINGMeasure the accuracy of POCUS for the diagnosis of acute respiratory failure
POCUS consists of an ultrasound examination at bedside. We will perform lung ultrasound and the pattern of lung ultrasound will be used to diagnose the cause of acute respiratory failure. The reference standard will be the the final diagnosis by the clinician. The accuracy measures will include sensitivity, specificity, positive predictive value, and negative predictive value.
Time frame: 2 years
Measure the accuracy of POCUS plus Eko for the diagnosis of acute respiratory failure. AI-assisted lung auscultation for the diagnosis of the case of acute respiratory failure.
POCUS was described above. Ekos consists of a digital stethoscope. The lung auscultation pattern will be used to determine the cause of acute respiratory failure. POCUS and Eko will be integrated to establish the cause of acute respiratory failure. The reference standard will be the final diagnosis by the clinician.
Time frame: 2 years
Agreement between POCUS and Eko CORE
We will measure Kappa statistic.
