Cerebral 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.

Dr. Frost has no relevant financial conflicts to disclose. C erebral oximetry has been studied for more than 30 years, and has been commercially available to clinicians for more than 2 decades. 1,2 However, whereas pulse oximetry has been a standard of care for decades, only recently has cerebral oximetry been extensively studied and adapted to investigate changes in oxygen delivery to the brai...

Often, advances in medical technology become available on a widespread basis before a controlled scientific experience has accumulated to carefully delineate the indications, uses, and pitfalls of such technology I feel this certainly is the case with pulse oximetry and this issue is partially addressed by the data of Loggan, Kerby and Pingleton (see page 242). The accuracy simplicity and usefu...
متن کاملVenous oximetry
Tissue hypoxia is the central pathophysiological process in shock and an important co-factor in the development of organ dysfunction. Hemodynamic parameters, usually used to assess the perfusion of organs and tissues, like arterial blood pressure, heart rate, urine output and blood gases can be normal in the presence of tissue hypoxia and cannot rule out imbalances between global oxygen supply ...
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...
