Quick JVP
Description
• Aids providers in learning bedside estimation of jugular venous pressure (JVP)
• Eliminates fumbling with rulers in trying to measure vertical distention of neck veins
• Provides quick visual reminders of anatomic landmarks and subject positioning
• Allows continuous readings with subjects in various positions
• Can be used with various smart phone models/ sizes
Quick JVP aids physicians in practicing the bedside physical examination of the jugular veins and estimating jugular venous pressure (JVP). Typically this physical exam technique is accomplished with a subject’s head and upper torso elevated between 30 and 60 degrees. With proper positioning the jugular veins serve as a visual manometer, the meniscus being the point of collapse of the external jugular vein or the highest point of oscillation of the internal jugular vein. The vertical distance of this meniscus above the sternal angle is often measured using 2 rulers, one held horizontally and another vertically and touching the sternal angle. Assuming the right atrium of the heart lies 5 cm below the sternal angle, JVP by physical exam equals the sum of the vertical venous distention above the sternum (cm) plus 5 cm (expressed as cm of water pressure). The usefulness of this time-honored physical exam finding may be limited by whether not examiners perform it correctly and by estimations of measurements involved. When the subject and smart phone are correctly positioned the APP automatically calculates the vertical height of jugular distention and gives an estimate of JVP.

Disclaimer: Quick JVP is intended to be used to help estimate a vertical distance from a reference point on an inclined line with respect to the level horizontal plane. It is used to help physicians understand and practice the bedside maneuvers used to assess jugular venous distention, part of a physical examination. It is not intended to be used as a medical device used for diagnosing patients. It has not been directly studied or compared with bedside assessments of JVP measured by traditional bedside physical exams or against any other gold standard, such as invasive venous pressure transducing. Estimates of jugular venous pressure using Quick JVP should always be verified by other methods. The information obtained by using quick JVP is intended for teaching purposes and is not intended for clinical diagnosis or use in clinical decision making.
