有创及无创血气检测技术的研究进展OA

Blood gas analysis is widely applied in medicine,with a development history of over 200 years.Currently,the commonly used clinical method for blood gas analysis is invasive blood gas detection technology.Although this technology has been well-developed,it still presents numerous issues in clinical practice,such as infection,bleeding,and discontinuous monitoring caused by invasiveness.To address the limitations of invasive techniques,non-invasive blood gas monitoring technology has emerged and continued to evolve.Traditional non-invasive technologies,such as pulse oximeters and capnogram,have limitations in accuracy.Among new technologies,gas chromatography-mass spectrometry,tunable diode laser absorption spectroscopy,and photoacoustic spectroscopy have been gradually applied.This paper elaborated on the development history and detection technologies of blood gas analysis,explored the development of non-invasive blood gas analysis technology,with a particular focus on the application of cavity ring-down spectroscopy based on optics in non-invasive blood gas analysis monitoring technology,and prospected the future development direction of non-invasive blood gas analysis technology,aiming to provide references for the research and development of related equipment.
