| Abstract: | Objective A type of reflecting oximeter was designed and its feasibility and clinical value were evaluated. Methods The reflecting oximeter consisting of converter, driver, central processing module and liquid-crystal display module. The reflective probe, central post-treatment system and digital display system was connected by one-to-three optical-fiber cable. We measured the value of oxygen saturation in 10 rabbits under different blood oxygen concentration and 20 patients with trunk aneurysm under different temperature control.Results There was no significant difference (P>0.05) between the values of oxygen saturation (SaO 2) and blood gas determined by reflecting oximeter or conventional oximeter. Conclusion It is demonstrated that the design of reflecting oximeter is successful and satisfying the requirements in clinical application. |
