Evaluation 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 کاملPulse Oximetry
The principal advantage of optical sensors for medical applications is their intrinsic safety since there is no electrical contact between the patient and the equipment. (An added bonus is that they are also less suspect to electromagnetic interference). This has given rise to a variety of optical techniques to monitor physiological parameters: for example, the technique of Laser Doppler veloci...
متن کاملPulse Oximetry
Introduction There is no doubt that pulse oximetry represents the greatest advance in patient monitoring in many years. It has the unique advantage of continuously monitoring the saturation of hemoglobin with oxygen, easily and noninvasively, providing a measure of cardio-respiratory function. By virtue of its ability to quickly detect hypoxaemia, it has become the standard of care during anaes...
متن کاملInfant home respiratory monitoring using pulse oximetry.
Respiratory rate (RR) is a valuable early marker of illness in vulnerable infants, but current monitoring methods are unsuitable for sustained home use. We have demonstrated accurate measurement of RR from brief recordings of pulse oximeter plethysmogram (pleth) trace in full-term neonates in hospital. This study assessed the feasibility of this method in preterm infants during overnight record...
متن کاملDoes ambient light affect the accuracy of pulse oximetry?
OBJECTIVE Determine whether ambient light affects the accuracy of pulse oximetry readings. DESIGN Prospective, repeated-measures study. SETTING A photographic darkroom. SUBJECTS Forty-five faculty and students at a university, none of whom had pale skin, dark skin, or evidence of cardiopulmonary disease. Any nail polish was removed. METHODS Five light sources were individually tested: i...
