Disclosures§ I have no financial disclosures for this
presentation
Goals of the Workshop§ To learn what point of care ultrasound is and how it
differs from traditional ultrasound imaging
§ To learn methods to become proficient in point of care ultrasound
§ To discuss a few basic ultrasound principles
§ To participate in the hands on POCUS skill sessions
What is POCUS?§ Clinician performed ultrasound at the bedside
§ Focused studies:§ Designed to answer a specific question§ Or perform a procedure§ Can be performed in minutes§ Can provide timely information for medical decisions
§ Ultrasound is a safe imaging modality
Applications for POCUS§ Cardiac§ Critical care/volume status§ Trauma§ Lung (edema, pneumothorax)§ AAA§ Biliary§ Renal/Bladder§ OB/GYN§ Gastrointestinal§ DVT§ Musculoskeletal§ Cellulitis v. Abscess§ Ocular
§ Procedural§ Paracentesis§ Thoracentesis§ Vascular access
§ Central § Peripheral
§ Abscess drainage§ Lumbar puncture§ Arthrocentesis
Methods to Learn POCUS§ Undergraduate Medical Education
§ Part of Curriculum§ POCUS rotation§ Radiology Rotation§ ICU Rotation/Cardiology Rotation
§ Internal Medicine Residency Training:§ 2013 study in J Grad Med Ed:
§ 25% of programs have formal POCUS curriculum§ 25% more planning to develop curriculum
§ Self-directed learning
Methods to Learn POCUS§ Attending Physician
§ Basic ultrasound training program:§ ACP offers 2-day course
§ Online/In-person CME training (many resources)
§ Find a mentor
§ Review radiology US images
§ SCAN OFTEN
Basic Ultrasound Principles§ Pulse-echo principle:
§ A brief sound pulse is generated and transmitted into the body
§ The transducer then spends time listening for echoes (sound returning to the transducer)
§ Determines depth of object on the display
§ Determines the brightness of the pixel on the greyscale image

Transducers
Higher frequency: superficial structures, more detailLower frequency: deeper structures, less detail
