The airway is not at any particular risk with this injury. Therefore. respiratory rate and pulse oximetry are not priority assessments. Electric current travels through the body from the entrance site to the exit site and can seriously damage all tissues between the two sites. Early cardiac damage from electrical injury includes irregular heart rate. rhythm. and ECG changes. Range of motion and neurologic assessments are important. However. the priority is to make sure that the heart rate and rhythm are adequate to support perfusion to the brain and other vital organs.
