Ultrasound Scan with TEX Ultrasound

Point of care ultrasound (POCUS) has increasingly become more common in expediting patient assessment and diagnosis in emergency settings. As ultrasound continues to become the imaging modality of choice for helping to assess patients, comprehensive education around POCUS imaging has become a necessity for clinicians. Unfortunately, ultrasound training can be challenging due to a shortage of experienced teachers and budget constraints. 

However, advanced ultrasound technology, including artificial intelligence (AI)-assisted scanning, on-system tutorials, guided protocols, and self-testing features, is revolutionizing POCUS education and helping novice users quickly become accustomed to the POCUS environment.

The Role of Technology in Modern POCUS Education

Continuous learning is a necessity in the emergency medicine field, where new techniques and advancements emerge frequently. Staying updated with the latest technology in POCUS not only enhances diagnostic accuracy but also can improve patient outcomes. Integrating advanced technology into POCUS education helps to reduce the learning curve for new clinicians entering the field, as well as clinicians who are adopting the new technology, and enables experienced users to get accustomed to advanced diagnostic tools more quickly.

AI-Assisted Ultrasound Scanning

  • Ultrasound systems that offer AI-assisted scanning can improve POCUS scanning and patient outcomes by providing clinicians access to real-time information at the bedside. Technologies that utilize artificial intelligence to aid in real-time diagnostics help to streamline the learning process. These tools can analyze images and provide instant feedback, enabling clinicians to interpret scans accurately.

    One significant benefit of AI-assisted ultrasound scanning is a reduced learning curve. For instance, automated measurements and analysis make it easier for users to understand and apply their findings. This not only enhances diagnostic confidence but also saves time.

    A 2023 cardiac ultrasound study found that clinicians who used devices with AI-assisted scanning could identify reduced systolic function more accurately than those who did not have AI features available to them.

    The conclusion of the study determined that POCUS devices with deep learning functionality may improve image acquisition and interpretation by novices. 1

    AI can also guide users through complex scans, ensuring they capture the required views, and highlight areas that require further attention. By providing real-time support, AI enables clinicians to make informed decisions more quickly, improving patient care.

Guided Ultrasound Protocols

Guided ultrasound protocols provide a structured approach to scanning and help mitigate inconsistencies by offering clear instructions for common procedures. An ultrasound machine with a guided workflow can enable clinicians to recognize abnormalities simply, swiftly, and accurately – for example, features that automate exam steps based on user-defined protocols. From automatic image annotations to activating modes and measurement packages, ultrasound systems with guided protocol technology can reduce the chance of incomplete exams, allowing for more efficient quality assurance reviews. Guided protocols can help provide detailed instructions for the following exams: 
·       RUSH exam – The RUSH exam stands for Rapid Ultrasound for Shock and Hypotension. POCUS can help to identify shock in patients in the emergency department, enabling clinicians to take the appropriate life-saving measures. The initial RUSH protocol, now often remembered by the pneumonic HI-MAP, evaluates five major areas: Heart, IVC, Morrison’s pouch, Aorta, Pneumothorax. This has since been expanded to a broader view, or the “pump, tank, pipes” protocol. This refers to evaluating several organ systems and adds views to evaluate for pulmonary effusion and interstitial edema, as well as for DVT in the lower extremities.2
·       eFAST exam – The eFAST exam, or Extended Focused Assessment with Sonography in Trauma, uses ultrasound imaging to examine a patient’s heart, lungs, and abdomen to detect peritoneal fluid, pericardial fluid, pneumothorax (otherwise known as a collapsed lung), and hemothorax (blood collection in the hollow space between the lungs and chest) in a trauma patient.3
·       BLUE protocol – In POCUS, the BLUE protocol is known as the Bedside Lung Ultrasound in Emergency. This exam is performed to detect respiratory failure at the bedside immediately after the physical examination, and before echocardiography.4

Using guided protocols provides educational value by helping clinicians learn the rationale behind each step, improving their understanding of the procedure. This deeper knowledge translates into better diagnostic accuracy and patient care.

On-System Ultrasound Tutorials

  • Ultrasound devices with on-system tutorials provide immediate access to instructional content, helping users practice and refine their skills at their own pace. Clinicians can learn and review techniques through transducer placement guidance, reference images, and self-test image acquisition whenever they need to, without relying on external resources. This flexibility is particularly beneficial for busy healthcare professionals who may not have the time to attend formal training sessions. On-system tutorials also support continuous learning, allowing users to revisit specific tutorials on demand reinforcing their knowledge and building their confidence.

On-Board Ultrasound Self-Testing Features

Ultrasound systems with self-assessment tools allow clinicians to evaluate their skills and identify areas for improvement. Self-testing provides immediate feedback, enabling clinicians to adjust their techniques in real-time. This iterative learning process helps clinicians build competence. Over time, they can track their progress and see tangible improvements in their POCUS skills.

By incorporating self-testing into their routine, clinicians can maintain high standards of practice. Regular assessment helps reinforce learning and keeps skills sharp, ultimately benefiting patient care.

Benefits of Integrating Educational POCUS Technologies

The integration of AI-assisted scanning, on-system tutorials, guided protocols, and self-testing features in an ultrasound system creates a comprehensive toolset for POCUS clinicians. This integrated approach accelerates the learning curve for POCUS users. Clinicians can quickly acquire the necessary skills and knowledge, reducing the time required to become proficient in POCUS. This efficiency is crucial in a healthcare environment where time and ultrasound training are often limited.

Better-trained practitioners lead to improved patient outcomes. When clinicians are confident in their POCUS abilities, they can make faster and more accurate diagnoses. This leads to timely interventions and better overall patient care.
