The evolution and continuing adoption of point-of-care ultrasounds (PoCUS) have enabled clinicians to make immediate diagnoses for a broad spectrum of conditions. As technology and practice advances, one of the areas that PoCUS has made inroads into is the diagnosis of obstructive sleep apnea (OSA), which traditionally has required resource-heavy evaluation mechanisms such as overnight polysomnography. In this infographic, we describe a recent systematic review and meta-analysis that examines the performance of a variety of bedside PoCUS measurements for the diagnosis of OSA.
