Influence of posture and reference point on central venous pressure measurement.
highly purified animal insulins.3 Patients should therefore be transferred to human insulin onlv when there is a medical indication, under a doctor's guidance, and after having been informed that a change in symptoms ofhypoglycaemia could occur. As advocated previously,"' a large randomised clinical trial is now needed to establish definitively whether there is an increased risk of severe hypog...
متن کاملVariability in the establishment of an external reference point for central venous pressure measurement in children.
OBJECTIVE To investigate the variability in the establishment of the midaxillary line as external reference point (ERP), by different healthcare workers, for the measurement of central venous pressure in children. METHODS Descriptive and correlational study carried out in a pediatric intensive care unit of a teaching hospital. During the establishment of the midaxillary line as ERP for centra...
متن کاملDetermination of Central Venous Pressure from Intraocular Pressure
Background: In many clinical situations, knowledge of central venous pressure (CVP) is important. Measurement of CVP is not always possible. Objective: To determine if intraocular pressure (IOP) can be used as an estimate for CVP. Methods: IOP and CVP were measured concurrently in 30 candidates of coronary artery bypass graft surgery. Those with carotid artery or jugular venous diseases as we...
متن کاملInfluence of tissue pressure on central venous pressure/peripheral venous pressure correlation: An experimental report.
BACKGROUND Peripheral venous pressure (PVP) has been shown to correlate with central venous pressure (CVP) in a number of reports. Few studies, however, have explored the relationship between tissue pressure (TP) and PVP/CVP correlation. METHODS PVP and CVP were simultaneously recorded in a bench-top model of the venous circulation of the upper limb and in a single human volunteer after under...
متن کاملMeasurement of Central Venous Pressure Using Ultrasound in Emergency Department
BACKGROUND In order to assessment of intravascular fluid measurement of central venous pressure (CVP) is used via central venous catheterization (CVC). This procedure is highly invasive and may cause serious complications such as pneumothorax, infection, hematoma and etc. It is so valuable procedure if we can uses a less invasive or noninvasive procedure to assess patients intravascular fluid i...
