Lung POCUS for Pulmonary Care
Lung point-of-care ultrasound (POCUS) brings focused thoracic imaging to the bedside, helping trained clinicians assess the pleural surface, lung artifacts and peripheral pulmonary findings in real time. Lung POCUS can complement the clinical examination when evaluating respiratory presentations and monitoring changes over time.
How Lung POCUS Supports Pulmonary Care
Lung ultrasound can provide focused bedside information about pleural and peripheral lung findings. Interpretation should always be integrated with the patient's history, physical examination, clinical context and other diagnostic testing when indicated.
B-Lines & Interstitial Patterns
B-lines are vertical ultrasound artifacts arising from the pleural line. Their distribution and clinical context may contribute to the assessment of interstitial-alveolar patterns.
Pleural Effusion
Lung POCUS can identify and characterize pleural fluid at the bedside and may support localization before appropriately indicated pleural procedures.
Lung Consolidation
Peripheral lung consolidation may produce a tissue-like sonographic appearance. Dynamic or static air bronchograms may also be visible within consolidated lung.
Lung Sliding
Pleural movement can be assessed dynamically with ultrasound. Lung sliding is one component of a focused pleural examination and should be interpreted with other sonographic and clinical findings.
Pneumothorax Assessment
A focused examination may evaluate lung sliding, B-lines and the lung point when pneumothorax is clinically suspected. No single finding should be interpreted outside the complete clinical context.
Serial Reassessment
The portability of POCUS can support repeat focused lung examinations over time when clinically appropriate, allowing sonographic findings to be reassessed at the point of care.
Real Lung POCUS Findings
Explore pulmonary and pleural ultrasound findings captured with Sono Mobile® handheld ultrasound. These clips demonstrate how lung POCUS can visualize dynamic findings at the point of care.
Pleural Effusion, Lung Consolidation & Sonographic Air Bronchogram
This lung POCUS example demonstrates pleural fluid with adjacent consolidated lung and a sonographic air bronchogram, illustrating how bedside ultrasound can visualize pleural and peripheral pulmonary findings in real time.
Pleural Effusion, Lung Point & Lung Flapping
A Sono Mobile® lung POCUS clip demonstrating pleural effusion with dynamic sonographic findings including lung flapping and the plankton sign. Ultrasound findings should be interpreted together with the complete clinical assessment.
Pleural Effusion, Curtain Sign & Lung Sliding
Dynamic lung ultrasound demonstrates pleural movement and the relationship between aerated lung, the diaphragm and pleural fluid during respiration.
B-Lines & Interstitial-Alveolar Pattern
This lung ultrasound clip demonstrates multiple B-lines. Their number, distribution and appearance should be interpreted within the patient's clinical context rather than as an isolated diagnostic finding.
Integrating Lung POCUS into Clinical Assessment
Lung POCUS is most useful when sonographic findings are integrated with the clinical picture rather than interpreted in isolation. Depending on the presentation, pulmonary ultrasound may be combined with focused cardiac, vascular or other point-of-care ultrasound examinations.
This multi-organ approach may be particularly relevant when evaluating undifferentiated dyspnea, respiratory deterioration or hemodynamic instability.

Handheld Ultrasound for Lung POCUS
Portable ultrasound can bring focused lung imaging directly to the bedside, clinic or other point-of-care environments. Sono Mobile® wireless handheld ultrasound is designed to support mobile clinical workflows without requiring a traditional cart-based ultrasound system.
For clinicians performing both lung and cardiac POCUS, Sono Mobile® CL64 combines convex, linear and phased-array capabilities within one wireless handheld platform.
One Platform for Multi-Organ POCUS
Respiratory presentations may require more than an isolated lung view. Access to lung, cardiac and vascular ultrasound capabilities within a portable platform can support a more integrated point-of-care workflow when clinically appropriate.

Lung POCUS FAQ
What is lung POCUS?
Lung POCUS is a focused point-of-care ultrasound examination of the pleural surface and peripheral lung performed by a trained clinician to answer defined clinical questions at the bedside. It complements rather than replaces comprehensive clinical assessment and other imaging when indicated.
What can be assessed with lung ultrasound?
Depending on the clinical question and operator training, lung ultrasound may assess findings such as lung sliding, A-lines, B-lines, pleural fluid and peripheral lung consolidation. Sonographic findings should always be interpreted in clinical context.
What do B-lines mean on lung ultrasound?
B-lines are vertical artifacts arising from the pleural line and extending through the ultrasound image. Their number and distribution may occur in different pulmonary conditions and should not be interpreted as a stand-alone diagnosis.
Can lung POCUS help assess pneumothorax?
Lung ultrasound can evaluate findings associated with pneumothorax, including lung sliding and the lung point. Absence of lung sliding alone is not specific for pneumothorax and should be interpreted together with other ultrasound and clinical findings.
Can handheld ultrasound be used for lung POCUS?
Yes. Handheld ultrasound can support focused lung imaging when used by appropriately trained clinicians. Portability can be particularly useful for bedside examinations and serial reassessment in point-of-care environments.
Can lung POCUS be combined with cardiac ultrasound?
Yes. Depending on the clinical presentation, focused lung findings may be integrated with cardiac, vascular or other POCUS examinations to provide additional bedside information.
