[Assessment of jugular vein hemodynamics to determine physiological activity during mental work]
Abstract:
Venous cerebral hemodynamics has been studied in 20 virtually sound military personnel. 120 instrumental tests were carried out. Blood flow rate in proximal and distal parts of internal jugular veins has been determined by means of ultrasonic doplerography. Blood flow rate in a distal part of internal jugular vein was shown increased considerably during small "ortostasis" conditions, that's why it is advised to determine blood flow rate in a distal part of jugular vein when we assess physiological activity of mental work, but for all that time averaging of max. blood flow in internal jugular vein should be taken as a control index.

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 the...
Assessment of radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
Pre-Procedural Preparation
Assessment of apical pulse
Assessing the apical pulse is a critical nursing procedure, particularly indicated for:
