MEDICAL INTELLIGENCE Cerebral Monitoring: Jugular Venous Oximetry
The internal jugular vein exits the skull and continues its course, within the carotid sheath, beneath the sternocleidomastoid muscle in a posterolateral approximation to the carotid artery. The jugular bulb is the dilated portion of the jugular vein just below the base of the skull and is the preferred site for blood sampling (see Figure 1). Although blood in the jugular bulb is derived from b...
متن کاملVenous oximetry
Tissue hypoxia is the central pathophysiological process in shock and an important co-factor in the development of organ dysfunction. Hemodynamic parameters, usually used to assess the perfusion of organs and tissues, like arterial blood pressure, heart rate, urine output and blood gases can be normal in the presence of tissue hypoxia and cannot rule out imbalances between global oxygen supply ...
متن کاملContinuous jugular venous oximetry in the neurointensive care unit--a brief review.
PURPOSE To describe the technique of continuous jugular venous oxygen saturation (SjVO(2)) monitoring and review its applications in the neurointensive care unit (NICU), with special reference to the management of raised intracranial pressure (ICP) following severe acute brain injury. SOURCE This narrative review is based on a selection of current literature on SjVO(2) monitoring in conjuncti...
متن کاملThe value of venous oximetry.
PURPOSE OF REVIEW Maintenance of adequate tissue oxygenation is an important task in intensive care units. In this context, venous oximetry by obtaining mixed venous oxygen saturation or central venous oxygen saturation has been discussed as useful monitoring parameters. This review discusses the physiology and clinical application of these parameters. RECENT FINDINGS No study has so far demo...
متن کاملThe jugular venous pressure revisited.
Assessment of the jugular venous pressure is often inadequately performed and undervalued. Here, we review the physiologic and anatomic basis for the jugular venous pressure, including the discrepancy between right atrial and central venous pressures. We also describe the correct method of evaluating this clinical finding and review the clinical relevance of the jugular venous pressure, especia...
