Abstract
Pressing a blood vessel makes stopping natural flow of blood and brings into a change of color in surface of tissues from red to white. This phenomenon is called "ischemia". The purpose of this work is to discuss the ischemia dyamics where the color of surface due to ischemia changes from red to white or from white to red when a force changing with respect time is given to our body. We also compare the dynamics of ischemia with that of deformation of tissues.
