Overview
Brief Summary
Patients receiving a point-of-care ultrasound will be randomized into a portable, handheld device or a traditional cart-based ultrasound machine to compare diagnostic capability.
Detailed Description
Patients who require a point-of-care ultrasound examination of their kidneys, gallbladder, heart, lung, or aorta will be enrolled. Once enrolled, the patient will be randomized to receive the point-of-care ultrasound using a portable, handheld ultrasound or a traditional cart based model. The ultrasound examinations will be performed by emergency medicine post-graduate year 1-3 residents or an ultrasound fellow and reviewed by the supervising emergency medicine attending physicians credentialed in performing and interpreting point-of-care ultrasound. Based on the clinical presentation, the provider will perform one of the following ultrasounds: cardiac to assess ejection fraction ( \<50%, 30-50%, \<30%), lung to assess for presence or absence of B-lines, gallbladder to assess for the presence or absence of gallstones, renal to assess for the presence or absence of hydronephrosis, or aorta to assess for the presence or absence of an aneurysm. The diagnostic accuracy of the portable, handheld and the cart-based model will be assessed using the following as the diagnostic standard: cardiology-interpreted echocardiogram, radiology-interpreted ultrasound or computed tomography, or quality review of the point-of-care ultrasound by 3 ultrasound fellowship trained physicians.

Eligibility Criteria
Inclusion Criteria
- •English and Spanish-speaking patients, who require a gallbladder, cardiac, renal, aorta, or lung ultrasound based on the discretion of the treating physician.
Exclusion Criteria

Outcomes
Primary Outcomes
Diagnostic Accuracy
Time Frame: 1 day
The primary outcome will be difference in diagnostic accuracy between the two methods (the percent of diagnostic accuracy of the hand-held and the percent of diagnostic accuracy of the cart-based model).
Secondary Outcomes
- Image Quality by Expert Review(1 day)
