Source: Jaideep S. Talwalkar, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT The physical examination requires the use of all of the provider's senses to gain information about the patient. The sense of touch is utilized to obtain diagnostic information through palpation. The specific parts of the examiner's hand used for palpation differ based on the body part being examined. Because of their dense sensory innervation, the finger pads are useful for fine...

Source: Alexander Goldfarb, MD, Assistant Professor of Medicine, Beth Israel Deaconess Medical Center, MA Abdominal palpation, if performed correctly, allows for examination of the large and relatively superficial organs; for a skilled examiner, it allows for assessment of the smaller and deeper structures as well. The amount of information that can be obtained by palpation of the abdominal area also depends on the anatomical characteristics of the patient. For example, obesity might make...

Source: Suneel Dhand, MD, Attending Physician, Internal Medicine, Beth Israel Deaconess Medical Center Disorders of the respiratory system with a chief complaint of shortness of breath are among the most common reasons for both outpatient and inpatient evaluation. The most obvious visible clue to a respiratory problem will be whether the patient is displaying any signs of respiratory distress, such as fast respiratory rate and/or cyanosis. In a clinical situation, this will always require...

Source: Suneel Dhand, MD, Attending Physician, Internal Medicine, Beth Israel Deaconess Medical Center The cardiac assessment is one of the core examinations performed by almost every physician whenever encountering a patient. Disorders of the cardiac system are among the most common reasons for hospital admission, with conditions ranging from myocardial infarction to congestive heart failure. Learning a complete and thorough cardiac examination is therefore crucial for any practicing physician.

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

2023
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...
FAQs
Correlation begins by identifying the precise point and quality of a palpable finding, then matching that location with the structure displayed on real-time ultrasound. Tenderness, stiffness, movement, or a mass can be considered alongside tissue depth and visual appearance. This pairing helps clinicians determine which accessible anatomical structure most plausibly accounts for what they feel during examination.
The examiner uses pressure deliberately while watching the image, so the tactile response and the visualized structure are assessed at the same moment. This links a sensation such as stiffness or tenderness to a specific tissue location rather than treating palpation and imaging as separate observations. The approach is especially relevant when superficial structures or joints are being assessed.
A palpable abnormality does not provide location or depth by itself. Real-time imaging adds those dimensions and allows the examiner to observe movement while the finding is assessed. Comparing the felt behavior with the structure’s ultrasound appearance can refine anatomical localization and help determine which accessible tissue corresponds to the examination finding.
Palpation supplies tactile information, while ultrasound supplies a visual representation of tissue location, depth, and appearance. Using both at once allows the clinician to connect a bedside sensation with the anatomy seen on the image. This combined interpretation supports diagnostic reasoning by relating a physical finding to an anatomical image rather than interpreting either source in isolation.
The examiner first identifies and characterizes the palpable finding during physical examination. The ultrasound probe is then positioned over the relevant region while the examiner applies controlled pressure and observes real-time images. Findings are correlated by matching tenderness, stiffness, movement, or a palpable mass with the displayed tissue’s location, depth, and appearance.
This approach is useful when clinicians need to localize findings in superficial soft tissues, joints, tendons, or other accessible structures. It can connect a palpable mass or area of tenderness with the corresponding anatomy and may support targeted procedures. The combined information also contributes to clinical evaluation when tactile findings alone do not establish precise localization.
In clinical education, the technique strengthens interpretation of bedside findings by showing how a tactile impression corresponds to visible anatomy. In research, it provides a way to examine physical examination findings alongside real-time ultrasound observations. This connection helps learners and investigators relate examination language, tissue location, depth, and appearance within the same assessment.
