Fetal pulse oximetry.
Pulse oximetry has become a standard of care in anesthetic, pediatric and neonatal practice (l,2). It measures the per cent saturation of hemoglobin based upon the Beer Lambart's spectrophotometric principle of differential absorption of red and infrared light waves (660 nm and 940 nm, respectively) by the oxyhemoglobin and reduced hemoglobin(3). Pulse oximetry has been recently adopted for con...
متن کاملFetal pulse oximetry for fetal assessment in labour.
BACKGROUND Fetal pulse oximetry (FPO) may contribute to the evaluation of fetal well-being during labour. OBJECTIVES To compare the effectiveness and safety of FPO with conventional surveillance techniques, using the results of randomised controlled trials. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group trials register (31 July 2004) and conducted a systematic liter...
متن کاملFetal pulse oximetry and cesarean delivery.
BACKGROUND Knowledge of fetal oxygen saturation, as an adjunct to electronic fetal monitoring, may be associated with a significant change in the rate of cesarean deliveries or the infant's condition at birth. METHODS We randomly assigned 5341 nulliparous women who were at term and in early labor to either "open" or "masked" fetal pulse oximetry. In the open group, fetal oxygen saturation val...
متن کاملEvaluation of oesophageal reflectance pulse oximetry in major burns patients.
Pulse oximetry is being used in everyday clinical practice in anaesthesia utilising a peripheral probe. However, it may be unreliable in certain clinical situations such as hypothermia, hypovolemia, vasoconstriction and decreased cardiac output. Similar situations occur in burns patients and, more importantly, burns to extremities which limit the sites available for measurement of peripheral ox...
متن کاملFetal pulse oximetry: the European experience
Pulse oximetry is a technique of fetal monitoring during labour based on non-invasive measurement of fetal arterial oxygen saturation. It has been shown in animal studies that metabolic acidosis occurred for a fetal arterial oxygen saturation below 30%. One of the main debates during initial experience in humans, was focused on the adequate cut-off for intervention (or non-intervention), and th...
