An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide. An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle , [ 1 ] but sometimes the femoral artery in the groin or another site is used.
Depending on the need to test for specific diseases such as ascites, special tests may be performed as a part of the physical examination. [2] An abdominal examination may be performed because the physician suspects a disease of the organs inside the abdominal cavity (including the liver, spleen, large or small intestines), or simply as a part ...
It is used for alert (conscious) people, but often much of this information can also be obtained from the family or friend of an unresponsive person. In the case of severe trauma, this portion of the assessment is less important. A derivative of SAMPLE history is AMPLE history which places a greater emphasis on a person's medical history. [2]
A peripheral vascular examination is a medical examination to discover signs of pathology in the peripheral vascular system.It is performed as part of a physical examination, or when a patient presents with leg pain suggestive of a cardiovascular pathology, typically peripheral artery disease.
Murphy's sign has a high sensitivity and negative predictive value, although the specificity is not high. [2] However, in the elderly the sensitivity is markedly lower; a negative Murphy's sign in an elderly person is not useful for ruling out cholecystitis if other tests and the clinical history suggest the diagnosis.
A review of systems (ROS), also called a systems enquiry or systems review, is a technique used by healthcare providers for eliciting a medical history from a patient. It is often structured as a component of an admission note covering the organ systems, with a focus upon the subjective symptoms perceived by the patient (as opposed to the objective signs perceived by the clinician).
• The pGALS assessment is a simple evidence-based approach to musculoskeletal assessment based on the adult GALS (Gait, Arms, Legs, Spine) screen and has been shown to have high sensitivity to detect significant abnormalities • pGALS is primarily aimed at the school aged child, but younger children will often comply with pGALS, especially ...
It is a typical example of how to organise a structured examination answer for medical students and physicians when they are challenged with a question. [1] It is also a way of constructing answers to questions from patients and their relatives in a logical manner, and structuring articles and reference texts in medicine.
