AIM To study the effects of change rate of electromagnetic fields (EMF) on blood apparent viscosity and coagulation and find a new physical way to reduce the blood viscosity and restrain coagulation. METHODS A generator producing different d E /d t and d B /d t EMF was developed. The blood sample was treated with device and then blood apparent viscosity and coagulation progress were detected. RESULTS With radiation of d E /d t , the blood apparent viscosity ( η ) decreased ( P <0.01), the coagulation time ( t r ) got slow ( P <0.01), the biggest clotting strength ( τ m) weaker ( P < 0.01 ) compared with d E /d t treatments, the d B /d t had more significant influence on blood. CONCLUSION d B /d t can improve the hemorheological performance.
