Point-of-care ultrasound to help diagnose sudden shortness of breath

Added Diagnostic Value of Point of Care Ultrasound in Acute Dyspnea: a Prospective Observational Study

Observational Region Skane · NCT05782478

This will test whether quick bedside ultrasound used by emergency doctors helps identify the cause of sudden shortness of breath in adults with low oxygen or fast breathing.

What this trial studies

Dyspnea is a common and time-sensitive problem in the Emergency Department that can have many causes. In this prospective observational study, emergency medicine specialists and residents at two Swedish EDs will receive brief training and certification in a structured dyspnea POCUS protocol. Trained clinicians will perform focused lung (8 or 14 zones), cardiac (subcostal, parasternal, apical four-chamber) and inferior vena cava scans, and diagnostic accuracy will be compared before and after POCUS use. The study enrolls adults triaged as highest or second-highest priority who meet prespecified oxygenation or respiratory rate criteria at the Lund and Helsingborg sites.

Who should consider this trial

Good fit: Adult ED patients triaged at the highest or second-highest priority who present with shortness of breath, oxygen saturation <90% on room air, or respiratory rate >25/min with oxygen saturation <95% on room air.

Not a fit: Patients who require immediate life-saving interventions that would be delayed by study procedures or patients discharged from the ED without admission are unlikely to benefit from the intervention.

Why it matters

Potential benefit: If successful, this could lead to faster and more accurate ED diagnoses so patients get the right treatment sooner.

How similar studies have performed: Previous studies have shown strong diagnostic performance of POCUS for conditions like heart failure and pneumonia, but most were performed by highly experienced ultrasound operators rather than a broad mix of ED physicians.
