upper extremity arterial function test

The upper extremity arterial function test is an auxiliary test for checking whether the arteries are normal. The structure and function of the upper limbs of normal people are normal, the blood flow of the hands is abundant, and the skin is flush red. After exerting pressure on the palm and subcutaneous tissues of the palm, the skin temporarily becomes slightly pale, and the flushing is quickly restored after the pressure is removed. When the upper extremity arteries are occluded or paralyzed, the blood flow in both hands is reduced, and the palms are obviously pale after being pressurized. The time to restore flushing after withdrawal is significantly longer than that of normal people. Through this examination, the corresponding symptoms can be judged.
