Ultrasound of Lung and Pleura

Ultrasound has become an invaluable tool in the evaluation of lung and pleural pathologies, offering rapid and accurate diagnostic insights at the bedside. This comprehensive CME/CE course equips healthcare professionals with a focused understanding of lung and pleural ultrasound applications, particularly relevant in emergency, critical care, and primary care settings. Participants will explore the use of ultrasound to detect conditions such as pneumonia, pneumothorax, pleural effusion, and interstitial syndromes. The course outlines how to identify and interpret common artifacts, such as A-lines, B-lines, curtain signs, and lung sliding, each serving as key diagnostic indicators. Learners will gain expertise in selecting appropriate transducers, adjusting settings for optimal image acquisition, and applying the three-zone lung scan technique for structured evaluations. By developing proficiency in image interpretation, healthcare professionals will be empowered to integrate lung ultrasound into routine practice, enhancing diagnostic accuracy and expediting care delivery. This course is ideal for clinicians seeking to enhance their point-of-care ultrasound (POCUS) capabilities, improve patient outcomes, and make informed, real-time clinical decisions with confidence.

Educational Objectives

• Explain the normal anatomy of the lung and pleura relevant to ultrasound image acquisition.
• Select appropriate transducers and apply correct handling and machine settings for high-quality imaging.
• Interpret normal ultrasound artifacts, including A-lines, curtain sign, and lung sliding.
• Conduct diagnostic three-zone lung scans and interpret findings effectively.
• Describe the clinical utility of B-lines as diagnostic tools for interstitial syndromes and fluid overload.
• Identify pleural effusion using ultrasound, including characteristic artifacts such as the spine sign and sinusoid sign.

Who Should Do This Course

This course is designed for Physicians, Nurse Practitioners, Physician Assistants, and Registered Nurses involved in pulmonary care, critical care, emergency medicine, and internal medicine. It is especially valuable for specialists in Family Medicine, Pulmonology, Radiology, and Critical Care Medicine who seek to advance their point-of-care ultrasound (POCUS) competencies in evaluating lung and pleural abnormalities.

Did You Know?

• Lung ultrasound has a sensitivity of over 90% and specificity of over 95% for diagnosing pneumothorax compared to chest X-rays (Volpicelli et al., 2012).
• POCUS can reduce time to diagnosis by 30-50% in emergency settings, significantly impacting patient outcomes (Lichtenstein & Mezière, 2008).
• B-lines on ultrasound are predictive markers of pulmonary edema and can correlate with elevated BNP levels in heart failure (Picano et al., 2006).
• Ultrasound guidance can improve the detection of pleural effusion and reduce complications during thoracentesis by more than 70% (Miller et al., 2009).
• Curtain sign and lung sliding are reliable indicators used to rule out pneumothorax in point-of-care assessments (Alrajhi et al., 2012).
