This will aid in preparing for down range mitigation operations as well as establishing Hot, Warm, and Cold Zones. Do not depend on it hours into the incident as you should be referring to other guidebooks. Thus, there are a number of ways in which the responses can be summarized for display; the optimal visualization is guided by the question that is being pursued. The most effective measure of the PhNR and the optimal recording conditions are debated, but it is often measured from the pre-stimulus baseline to the trough of the response, or at a fixed time following the stimulus flash. The pERG is typically recorded with natural pupils. So, lets go back over the guide starting with the first section.
