Dual-mode Imaging of Cutaneous Tissue Oxygenation and Vascular Function
Accurate assessment of cutaneous tissue oxygenation and vascular function is important for appropriate detection, staging, and treatment of many health disorders such as chronic wounds. We report the development of a dual-mode imaging system for non-invasive and non-contact imaging of cutaneous tissue oxygenation and vascular function. The imaging system integrated an infrared camera, a CCD cam...
متن کاملMeasurement of skeletal muscle tissue oxygenation in the critically ill
Shock is a state of acutely reduced tissue oxygenation. In cardiogenic shock oxygen delivery (DO2) is reduced, but oxygen extraction is preserved. In septic shock DO2 is preserved, but oxygen extraction is decreased because of microvascular changes and disturbed metabolism. Global assessment of DO2 and oxygen consumption does not tell us enough about adequacy of regional perfusion. The aim of t...
متن کاملMuscle oxygenation by near-infrared-based tissue oximeters.
TO THE EDITOR: In a recent article, R. C. Davies et al. (2) presented the results of a study investigating the effect of eccentric exercise-induced muscle damage on the dynamics of pulmonary O2 uptake by near-infrared spectroscopy-based measurement of oxygenation in the vastus lateralis muscle. Although these results are of interest (1), we believe that certain points concerning the presentatio...
متن کاملEffects of Cold Water Immersion on Muscle Oxygenation During Repeated Bouts of Fatiguing Exercise
Postexercise cold water immersion has been advocated to athletes as a means of accelerating recovery and improving performance. Given the effects of cold water immersion on blood flow, evaluating in vivo changes in tissue oxygenation during cold water immersion may help further our understanding of this recovery modality. This study aimed to investigate the effects of cold water immersion on mu...
متن کاملFunctional adaptability of muscle fibers to long-term resistance exercise.
PURPOSE We compared the functional properties of muscle fibers from two groups of subjects that differed widely in their training history to investigate whether long-term resistance exercise alters the intrinsic contractile properties of skeletal muscle fibers. METHODS Vastus lateralis muscle biopsies were obtained from six sedentary males (NT group, age = 23 +/- 1 yr) and six males who had p...
