The Authors assess the utility of the on-line monitoring of SvO2 during 156 measurements of pulmonary capillary wedge pressure (PCWP) done on 52 Intensive Care Unit patients. The measurement was always right when the SvO2 increased more than 90%. The Authors found a good correlation between the SvO2 monitored during the measurement of the PCWP and the saturation of pulmonary capillary blood measured by cooximeter. These data suggest that the complex procedure to confirm the reliability of the measurement recommended by Gardner can be simplified by the observation of the trend of SvO2 on the monitor oximetrix. This allows to obtain saving time for the staff, saving blood for the patients, reduction of risk for the transmission of infective diseases due to the handling of blood and guarantees a further routinary control of reliability on the measure of PCWP.

UI MeSH Term Description Entries
D010092 Oximetry The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry. Pulse Oximetry,Oximetry, Pulse,Oximetries,Oximetries, Pulse,Pulse Oximetries
D011669 Pulmonary Wedge Pressure The blood pressure as recorded after wedging a CATHETER in a small PULMONARY ARTERY; believed to reflect the PRESSURE in the pulmonary CAPILLARIES. Pulmonary Artery Wedge Pressure,Pulmonary Capillary Wedge Pressure,Pulmonary Venous Wedge Pressure,Wedge Pressure,Pressure, Pulmonary Wedge,Pressures, Pulmonary Wedge,Pulmonary Wedge Pressures,Wedge Pressure, Pulmonary,Wedge Pressures, Pulmonary,Pressure, Wedge,Pressures, Wedge,Wedge Pressures
D002407 Catheterization, Swan-Ganz Placement of a balloon-tipped catheter into the pulmonary artery through the antecubital, subclavian, and sometimes the femoral vein. It is used to measure pulmonary artery pressure and pulmonary artery wedge pressure which reflects left atrial pressure and left ventricular end-diastolic pressure. The catheter is threaded into the right atrium, the balloon is inflated and the catheter follows the blood flow through the tricuspid valve into the right ventricle and out into the pulmonary artery.
