Thermal Disparity among Fingers and Its Amelioration by CO₂-Water Bathing in Connective Tissue Disease Patients

Figure 1

Time-course changes in Temp of each finger of the right hand (R1–5), before and after CO₂ bathing, in a 59-year-old female patient with Raynaud disease. Change in CV is also plotted. Temp: nailfold temperature; CV: coefficient of variation.
