All-organic optoelectronic sensor for pulse oximetry.
Pulse oximetry is a ubiquitous non-invasive medical sensing method for measuring pulse rate and arterial blood oxygenation. Conventional pulse oximeters use expensive optoelectronic components that restrict sensing locations to finger tips or ear lobes due to their rigid form and area-scaling complexity. In this work, we report a pulse oximeter sensor based on organic materials, which are compa...
متن کاملThe use of pulse oximetry in clinical veterinary anaesthesia
A commercial human pulse oximeter was used in several species to measure heart rate and arterial oxygen saturation (Sa02), and the results compared with those from an ECG and bench oximeter. The heart rates were always the same, but differences in the Sa02 ranged between 4.2 per cent to 10.3 per cent. Correlation coefficients between the two Sa02 measurement techniques ranged from 0.81 to 0.94,...
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 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 کاملSafe anaesthesia for all Indians: A distant dream?
© 2017 Indian Journal of Anaesthesia | Published by Wolters Kluwer Medknow Surgery is performed to save lives and improve the quality of life of patients. However, unsafe surgical care can lead to significant harm. The crude mortality rate after major surgery varies from 0.5% to 5%.[1] In the European Surgical Outcomes Study, an international, 7-day cohort study, 1855 out of the 46,539 adult pa...
