Point-of-care ultrasonography (POCUS) has emerged as a transformative tool in the management of acute respiratory distress syndrome (ARDS) in the intensive care unit (ICU), enabling real-time, non-invasive, and comprehensive assessments at the bedside. By integrating multi-system evaluations, POCUS facilitates personalized therapeutic strategies, early detection of complications, and optimized clinical decision-making.

Acute respiratory distress syndrome (ARDS) is a life-threatening condition characterized by severe hypoxemia, non-cardiogenic pulmonary edema, and diffuse lung inflammation1,2. It is triggered by various etiologies, including pneumonia, sepsis, and trauma, and is associated with a high mortality rate of approximately 40%. The pathophysiology of ARDS involves alveolar-capillary barrier damage, leading to impaired gas exchange and respiratory failure. Despite advances in critical care, ARDS remains a significant challenge in intensive care units (ICUs) worldwide.
The management of ARDS is complex and requires a multifaceted approach. Key challenges include the need for precise mechanical ventilation strategies to avoid ventilator-induced lung injury (VILI), timely detection of complications such as pneumothorax and deep vein thrombosis (DVT), and optimization of hemodynamic and nutritional support3,4. Traditional imaging modalities, such as computed tomography (CT), though highly accurate, are often impractical due to the risks associated with patient transport, radiation exposure, and delays in obtaining results. These limitations highlight the need for a dynamic, non-invasive, and bedside-accessible diagnostic tool to guide real-time decision-making.
Point-of-care ultrasonography (POCUS) has emerged as a transformative technology in critical care, offering real-time, multi-system evaluation at the bedside3,5,6. Initially developed for focused cardiac and abdominal assessments, POCUS has rapidly expanded to include lung, vascular, and diaphragmatic imaging7,8,9. Most core applications feature relatively short learning curves, enabling clinicians to achieve proficiency with focused training-as evidenced by near-universal adoption in Canadian EM residencies10. While advanced applications (e.g., ventricular function, complex lung pathology) require more extensive practice, standardized benchmarks like minimum scan volumes ensure competency across programs. Its portability, safety, and ability to provide immediate feedback make it particularly valuable in the management of critically ill patients, though quality assurance programs remain essential to safeguard accuracy. In recent years, POCUS has gained widespread acceptance as an essential tool for diagnosing and monitoring ARDS, with growing evidence supporting its role in guiding personalized treatment strategies.
While studies focusing solely on lung ultrasound (LUS) scores, such as those employing a 14-point protocol for prognostic evaluation11, provide valuable insights into pulmonary aeration and edema severity, ARDS is fundamentally a systemic disorder with multi-organ implications. Sole reliance on pulmonary aeration assessment offers an incomplete picture of the critically ill ARDS patient. In contrast to approaches limited to LUS scoring, comprehensive POCUS integrates five critical applications to address ARDS&#39;s multifactorial pathophysiology and guide specific interventions beyond prognosis. Lung ultrasound (LUS) systematically evaluates pulmonary aeration through 12 thoracic zones, quantifying B-line patterns (&#8805;3/zone indicates interstitial edema) and consolidations. The LUS score (0-36 scale) dynamically correlates with disease severity, where a score &#8805;20 predicts moderate-severe ARDS and guides lung recruitment maneuvers, such as prone positioning for &#34;spared&#34; posterior zones9.
Simultaneously, echocardiography assesses right ventricular (RV) dysfunction via RV/LV end-diastolic area ratio (&#62;0.6) and tricuspid annular plane systolic excursion (TAPSE &#60;15 mm), directly informing ventilator adjustments (e.g., lower PEEP for RV strain)12. Diaphragm ultrasound (DU) quantifies diaphragmatic weakness through thickening fraction (DTF &#60;20% predicts weaning failure) and excursion amplitude (&#60;10 mm), reducing reintubation rates by 59%13. For thromboembolic prophylaxis, lower extremity venous duplex screens for deep vein thrombosis (DVT) via a two-zone compression protocol, cutting pulmonary embolism incidence by 52% in high-risk cohorts14. Finally, gastric ultrasonography can calculate residual volume, identifying aspiration risk and reducing ventilator-associated pneumonia by 40% in randomized trials15. By synergizing these modalities -- tailoring PEEP via LUS/TTE, timing extubation with DU, preventing DVT, and optimizing nutrition -- POCUS transforms ARDS management into a dynamic, physiology-driven paradigm, bridging diagnostic precision with real-time therapeutic intervention.

The Application of Point-of-Care Ultrasonography (POCUS) in the Management of Acute Respiratory Distress Syndrome (ARDS) in the Intensive Care Unit

Acute respiratory distress syndrome (ARDS) is a life-threatening condition that necessitates dynamic, non-invasive monitoring for optimal management. Traditional imaging modalities, such as computed tomography (CT), are often limited by radiation exposure and patient instability, particularly in critically ill populations. Point-of-care ultrasonography (POCUS) has emerged as a transformative tool, enabling real-time, multi-system evaluation at the bedside. This protocol highlights five key applications of POCUS in ARDS management: (1) Lung ultrasound (LUS) for assessing pulmonary aeration, edema, and pleural effusion status; (2) Echocardiography to evaluate right ventricular dysfunction and fluid responsiveness; (3) Diaphragm ultrasound to quantify diaphragmatic dysfunction and predict weaning outcomes; (4) Lower extremity venous duplex for early detection of deep vein thrombosis (DVT); and (5) Gastric ultrasonography to optimize enteral nutrition and reduce aspiration risk. By integrating these POCUS modalities, clinicians can tailor personalized ventilation strategies, prevent complications, and ultimately improve patient outcomes. The use of POCUS not only enhances diagnostic accuracy but also supports timely clinical decision-making, making it an indispensable tool in the management of ARDS.

The ultrasound images were acquired in the EICU of Sir Run Run Shaw Hospital following standardized protocols using a portable ultrasound system. All patients underwent systematic evaluation following the sequence: lung-heart-diaphragm-stomach-lower extremity deep veins. For study design, we established two comparison groups: 1) a control group comprising patients with acute cerebrovascular disease demonstrating normal pulmonary findings, and 2) a positive control group consisting of ARDS patients meeting Berlin diagnost...

Here, we present a protocol for bedside POCUS application in ARDS management within the ICU. It details standardized techniques for lung, cardiac, diaphragm, venous, and gastric assessments to guide ventilation, predict weaning, and prevent complications.

We have organized standardized procedures for performing POCUS on ARDS patients in the intensive care unit. Bedside ultrasound technology has developed rapidly in multiple fields, yet there is a lack of standardized research specifically targeting patients with ARDS. To begin, perform a longitudinal scan in the intercostal space and locate the pleural line approximately 0.5 centimeters below the rib line, visible as a hyperechoic horizontal line.Identify A-lines as horizontal hyperechoic artifacts of the pleural line indicative of a high gas volume ratio beneath the pleura. Using M mode, check for the presence of the seashore sign, indicating normal lung sliding, or the stratosphere sign, indicating absent lung sliding, suggestive of pneumothorax. Then, identify B-lines as vertical hypoechoic artifacts originating from the pleural line that extend to the bottom of the screen and erase the A-lines.Now, check for the shred sign, represented by subpleural hypoechoic areas with irregular boundaries, indicating small consolidations. Look for a tissue-like pattern in areas of large consolidation, characterized by liver-like echogenicity. Use a right ventricular focused apical four-chamber view.At end diastole, trace the right ventricular endocardial border to measure the end diastolic area. Measure the right ventricular free wall thickness at end diastole. Now, use the M mode to measure tricuspid annular plane systolic excursion.Measure the inferior vena cava diameter and collapsibility during a sniff. Next, identify the diaphragm as a three-layered structure with a hypoechoic muscle layer between hypoechoic pleural and peritoneal lines. Record B mode clips or still images during end inspiration and end expiration.Then, measure the diaphragm thickness from the middle of the pleural line to the middle of the peritoneal line. Now, place the probe sagittal below the right costal margin between the midclavicular and anterior axillary lines to scan the right diaphragm, then, place the probe sagittal below the left costal margin between the anterior and midaxillary lines to scan the left diaphragm. For femoral vein assessment, place the patient in a supine position with hips externally rotated into the frog leg position to optimize exposure.For popliteal vein evaluation, maintain the knee in slight flexion between 15 and 30 degrees to avoid venous compression. In obese patients, use lateral decubitus or prone positioning to improve acoustic access and tissue displacement when standard views are inadequate. Start scanning the femoral zone at the inguinal crease to identify the common femoral vein.Move the probe distally to visualize the junction of the femoral vein and the deep femoral vein. Compress the vein every centimeter along its course to assess venous compressibility. Scan the popliteal zone from the popliteal vein to the confluence of the anterior tibial, posterior tibial, and peroneal veins.Compress the vein every one centimeter to confirm full compressibility. Identify the liver as the cephalad structure located on the left side of the screen. Locate the aorta or inferior vena cava and adjust the imaging depth to visualize their posterior boundaries or the vertebral body.Sweep the probe laterally from left to right while keeping it perpendicular to the skin. Identify the stomach, liver, pancreas, superior mesenteric artery, aorta, and inferior vena cava. Use the supine position to assess gastric fullness, noting that it cannot exclude the presence of contents.Place the patient in the right lateral decubitus position to allow gravitational flow of gastric contents into the antrum for more accurate volume measurement. Measure the cross-sectional area of the gastric antrum at the level of the aorta to avoid underestimation of volume. Ensure the aorta is correctly identified during measurement.Representative ultrasound images showed normal pulmonary findings, including visible pleural lines, A-lines, and the seashore sign. The presence of fewer than three B-lines per intercostal space was observed, but the concurrent appearance of a shred sign indicated focal pulmonary consolidation. A stratosphere sign was observed, characterized by static horizontal lines and absence of the seashore sign, indicating pneumothorax.Ultrasound imaging showed pleural effusion with accompanying pulmonary consolidation, as evidenced by air bronchogram signs. Varying degrees of pleural effusion accumulation were observed in two cases. Echocardiography revealed clear visualization of cardiac chambers, including both atria and ventricles.Diaphragm motion patterns were evaluated. Ultrasound assessment of the lower extremity veins showed compressibility testing at the common femoral vein and the popliteal vein. Ultrasound of the stomach showed an empty stomach with a bullseye appearance and minimal clear basal secretions.Repositioning the patient in right lateral decubitus allowed the gastric contents to gravitate toward the antrum. We have established that our comprehensive POCUS protocol enables time multi-system assessment to guide personalized management of ARDS in the ICU. Our protocol addresses the gap in standardized multi-organ POCUS guidelines for dynamic monitoring and intervention in ARDS beyond isolated lung ultrasound scoring.Future research will focus on standardizing training, validating POCUS-driven therapeutic algorithms, and exploring its utility in resource-limited settings.
