Point of care ultrasonography in the allergy and immunology clinic

Point of care (POC) clinical ultrasonography is used across multiple medical specialties to guide diagnosis and treatment, and to enhance the safety of invasive procedures. POC clinical ultrasonography is defined as a focused ultrasonographic examination, performed and interpreted by the treating clinician, to answer a specific question or to guide a procedure.1 Emergency department physicians were early adopters of POC ultrasonography in the late 1990's; since then, technological advances have resulted in enhanced portability, improved image quality, and user-friendly interfaces, expanding the use of POC ultrasonography at the bedside.
