Pulse 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 کاملCerebral oximetry: a replacement for pulse oximetry?
Cerebral oximetry has been around for some 3 decades but has had a somewhat checkered history regarding application and reliability. More recently several monitors have been approved in the United States and elsewhere and the technique is emerging as a useful tool for assessing not only adequate cerebral oxygenation but also tissue oxygenation and perfusion in other organs.
متن کاملPulseless Pulse Oximetry.
We read with great interest the article by Aldrich et al 1 in this issue of CHEST (see page 1484 ). In 2003, we reported our trial of measuring noninvasive arterial saturation during a pulseless situation (cardiopulmonary bypass [CPB]) by inducing a simulated pulse. 2 We were interested in fi nding a way to obtain pulse oximeter function during CPB at the time because we had experienced a morta...
متن کاملPulse Oximetry and Plethysmography
Stokes (1) reported that the colored substance in blood carries oxygen. This was followed by Hoppe-Seyler (2), who first crystallized this substance and coined the term hemoglobin. Additionally, it was shown that the pattern of light absorption changes when shaken with air (2). Hertzman (3) described using photoelectric plethysmography of fingers and toes as a dynamic analysis of the peripheral...
