| Abstract | The purpose of this pilot study was to identify the relationship between the ratio of the diameter/cross-sectional area of the internal jugular vein (IJV) and carotid artery and the central venous pressure (CVP). After obtaining approval from our Institutional Review Board, ultrasound images were repeatedly obtained from participants on consecutive days when a thoracic central line was in place. The CVP was then measured in standardized fashion, using our bedside monitors. A blinded observer measured the diameter of the common carotid artery and IJV, for comparison. Similarly, digital images were analyzed to compare an estimate of the cross-sectional areas of the same vessels. Six patients met enrollment criteria, and one patient was excluded after enrollment before any measurements being made. The remaining five patients had a mean age of 7 years (range: 9 months to 15 years) and mean burn size of 64% (SD, ±15), and no patients had inhalation injuries. All patients in this study were mechanically ventilated. Measurements were made from one patient while spontaneously breathing. One patient reading occurred while on vasopressor support (levophed at 2 µg/kg/hr). CVP values ranged from 1 to 25 mm Hg. Comparison of the ratio of the IJV/common carotid artery cross-sectional area with CVP revealed that a ratio of 2 or greater was associated with a CVP of at least 8 mm Hg (P < .001). These preliminary results suggest that if the cross-sectional area of the vein is at least twice that of the artery, then the CVP seems to be ≥8 mm Hg. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
