Interference of methylene blue with CO-Oximetry of hemoglobin derivatives.
Methylene blue (MB) is frequently used as an antidote in treating methemoglobinemia (1) because it facilitates the reducing activity of the NADPH-dependent methemoglobin reductase system in erythrocytes (2). However, MB absorbs strongly between 550 and 700 nm (Fig. 1 ), the same spectrophotometric region as that of the various hemoglobin derivatives: oxyhemoglobin (O2Hb), deoxyhemoglobin (HHb),...
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 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...
متن کاملMethemoglobinemia and Pulse Oximetry
In reviewing the article “Methemoglobinemia: Sudden Dyspnea and Oxygen Desaturation After Esophagoduodenoscopy,” in the August 2004 issue of RESPIRATORY CARE,1 I found the article suggested that, during the esophagoduodenoscopy procedure the patient’s blood oxygen saturation (measured via pulse oximetry) began to drop rapidly, and a saturation of 54% registered on the pulse oximeter while the p...
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...
