Effects of henna dye on oxygen saturation reading using pulse oximetry.
P oximetry is a non-invasive method that uses the spectrophotometric principle to monitor oxygen saturation in the blood. It produces a plethysmographic wave from which oxygen saturation is obtained.1 It is has become increasingly used in outpatient clinics and emergency rooms in addition to its use in critically ill patients and during anesthesia.1 Although it is an accurate method in reflecti...
متن کاملMechanism of erroneous Dextrostix readings.
The mechanism of hyper-reactivity of the Dextrostix system when contaminated with alcoholic skin cleaning agents was investigated. When sodium fluoride was supplied to block glucose oxidase activity and hydrogen peroxide was exogenously provided benzidine peroxidation could be preferentially studied. Benzidine hydrochloride was the most likely site of the hyper-reaction.
متن کاملEffects of intravenously administered indocyanine green on near-infrared cerebral oximetry and pulse oximetry readings
BACKGROUND Intravenously administered indocyanine green (ICG) may cause misreadings of cerebral oximetry and pulse oximetry in patients undergoing carotid endarterectomy under general anesthesia. The present study determined the effects of two different doses (12.5 mg vs. 25 mg) of ICG on regional cerebral tissue oxygen saturation (SctO2) and percutaneous peripheral oxygen saturation (SpO2). ...
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 کاملthe comparison between the impacts of henna and nail polish on pulse oximetry among healthy women
background & aim : pulse oximetry is a frequently used and standard non-invasive method for monitoring oxygen (o2)-saturation in blood. many factors including dark skin and pigmentation may effect on rate of saturation of the blood oxygen absorbed by pulse oximetry. the effect of nail polish and/or henna color on blood oxygen has not been yet identified and the present study has been carried ou...
