Photoplethysmography and Pulse Oximetry of Body Cavities and Organs*
Pulse oximetry is as a non-invasive photometric technique that provides non-invasively information about the global arterial blood oxygen saturation (SpO2 ) and heart rate, and has widespread clinical applications. This can be made possible via the peripheral pulse oximetry probes mainly attached to the finger, toe or earlobe. However, there is a need for monitoring perfusion on a more regional...
متن کاملEvaluation 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 کاملA pilot study of neonatal and pediatric esophageal pulse oximetry.
BACKGROUND In this pilot study we explored the suitability of the esophagus as a new measuring site for blood oxygen saturation (Spo(2)) in neonates. METHODS A new miniaturized esophageal pulse oximeter has been developed. Five patients (one child and four neonates) were studied. RESULTS Spo(2) values were obtained in the esophagus of all patients. A Bland and Altman plot of the difference ...
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 کاملNoncontact simultaneous dual wavelength photoplethysmography: a further step toward noncontact pulse oximetry.
We present a camera-based device capable of capturing two photoplethysmographic (PPG) signals at two different wavelengths simultaneously, in a remote noncontact manner. The system comprises a complementary metal-oxide semiconductor camera and dual wavelength array of light emitting diodes (760 and 880 nm). By alternately illuminating a region of tissue with each wavelength of light, and detect...
