Using Point of Care Ultrasound to Augment Acquisition of Physical Exam Skills: Veins and Arteries

Source: Joseph H. Donroe, Rachel Liu; Yale School of Medicine, USA Vascular diseases make up most cases of emergency hospitalization and carry a high mortality risk. Point-of-care ultrasound or POCUS enables accurate diagnosis of these diseases and shortens the time between detection of the cause and selection of appropriate treatment strategies, thus, reducing the patient mortality rate. POCUS offers a safe, low-cost, and less invasive bedside tool for examining arteries and veins, besides its...

Source: Joseph H. Donroe, Rachel Liu; Yale School of Medicine, USA Point of care ultrasound (POCUS) is used by clinicians for diagnosis, ongoing monitoring, and/or procedural guidance at the time of patient care. Many medical schools are now teaching POCUS as a part of their basic clinical skills training, in addition to history, physical exams, and clinical reasoning. Besides being an independent skill, POCUS is also an incredibly useful tool for augmenting the teaching and learning of the...

Source: Joseph H. Donroe, Rachel Liu; Yale School of Medicine, USA Point of Care Ultrasound or POCUS is easy to use, has enhanced mobility due to the smaller equipment needed, and may be carried out in a variety of settings. It is also far safer and cheaper than imaging techniques like computer tomography. POCUS can be helpful when certain physical exam findings are difficult to appreciate by palpation, percussion, or auscultation and can facilitate learning elements of the cardiac, pulmonary,...

This manuscript introduces a robust method of fabricating concave microwells without the need for complex high-cost facilities. Using magnetic force, steel beads, and a through-hole array, several hundred microwells were formed in a 3 cm x 3 cm polydimethylsiloxane (PDMS) substrate.
FAQs
The transducer generates clinically useful images by sending ultrasound waves into abdominal tissues and interpreting returning reflections from tissue and fluid interfaces. These reflections create real-time information about structures such as the bowel wall and lumen. Because the image changes during scanning, clinicians can also observe movement, including peristalsis, rather than relying only on static imaging.
Several observations are interpreted together rather than in isolation. Bowel wall appearance, luminal contents, peristalsis, gastric distension, and free fluid each contribute a different part of the assessment. Considering these findings as a combined pattern can help clinicians evaluate suspected obstruction, inflammation, or abnormal gastric contents while retaining the clinical context supplied by symptoms and examination.
Operator skill and clinical context strongly influence how GI POCUS findings are understood. The clinician must acquire and interpret images of moving gastrointestinal structures while relating them to the patient’s presentation. Repeat examinations can be valuable because the technique is repeatable, but repeated scans do not remove the need for appropriate interpretation or complementary imaging when the situation requires it.
At the bedside, the clinician uses a portable ultrasound transducer to survey the gastrointestinal region in real time. The examination focuses on bowel wall appearance, luminal contents, peristalsis, gastric distension, and any free fluid that can be evaluated. Findings are then interpreted alongside the physical examination and clinical question, rather than treated as an isolated image.
GI POCUS is especially relevant when a rapid bedside assessment is needed for abdominal pain, suspected bowel obstruction, gastrointestinal inflammation, or evaluation of gastric contents. Its portability supports use in emergency, inpatient, outpatient, and procedural settings. The same technique can therefore contribute at different points in care, while its findings remain dependent on operator skill and the patient’s clinical context.
It provides a repeatable bedside assessment without ionizing radiation, making it useful alongside physical examination and other imaging studies. Its main contribution is real-time visualization of gastrointestinal features and free fluid during clinical assessment. It should complement, not replace, broader diagnostic evaluation, because the meaning of observed findings depends on both scanning performance and the surrounding clinical picture.
