Integrating point-of-care ultrasound in the ED evaluation of patients presenting with chest pain and shortness of breath.

Objective: The differential diagnoses of patients presenting with chest pain (CP) and shortness of breath (SOB) are broad and non-specific. We aimed to 1) determine how use of point-of-care ultrasound (POCUS) impacted emergency physicians' differential diagnosis, and 2) evaluate the accuracy of POCUS when compared to chest radiograph (CXR) and composite final diagnosis.

Methods: We conducted a prospective observational study in a convenience sample of patients presenting with CP and SOB to the Emergency Department (ED).

Bedside Ultrasound Reduces Diagnostic Uncertainty and Guides Resuscitation in Patients With Undifferentiated Hypotension.

Objectives: Utilization of ultrasound in the evaluation of patients with undifferentiated hypotension has been proposed in several protocols. We sought to assess the impact of an ultrasound hypotension protocol on physicians' diagnostic certainty, diagnostic ability, and treatment and resource utilization.

Design: Prospective observational study.
