Radial artery occlus: A simple in home way of checking your circulation and getting first impression of its status would be to check your radial artery pulse just distal to your thumb base. If the occlusion is higher on the arm but the pulse is present, it's a good sign, then the occlusion is not total. If there is no pulse there, you may push on your fingernail. Usually blood comes back in less than 2 secs.
