We would like to make a number of comments. Respiratory specialists should be able to perform thoracic ultrasonography as this improves the investigation and treatment of patients with pleural disorders and, more importantly, the safety of pleural procedures. However, there is a requirement for standardized training of respiratory specialists. A number of guidelines describe the basic competencies required.4 Then the ultrasonography skills need to be maintained and reinforced by regular practice on patients with a variety of pleural disorders. Mentoring by an experienced radiologist can be helpful, someone who can give feedback on patients with more complex pleural disorders. Respiratory specialists should be aware of their thoracic ultrasonography skills limitations and know when to ask for advice from an experienced ultrasonography specialist. Finally, we would like to highlight the fact that thoracic ultrasonography should be used in conjunction with the clinical history, examination, and other imaging modalities (such as chest radiography or thoracic CT imaging) as thoracic ultrasonography complements but does not substitute for those procedures and tests.
