Abstract:
Ultrasound has been the most useful imaging tool for musculoskeletal disorders whereby peripheral nerve lesions constitute a substantial portion. High-resolution ultrasound enables elaboration of peripheral nerve morphology and reciprocal anatomy. However, limited literature is available for delineating standard positions and tracking skills. The present article incorporates a series of ultrasound images and videos to demonstrate how to scan the suprascapular, axillary, musculocutaneous, median, ulnar, and radial nerves. Overall, the authors aim to demonstrate the relevant nerve tracking techniques as regards the upper extremity.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
