<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">emergency medical treatment</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for first aid that I've seen before include "'Immediate emergency care (5,3)'" , "Treatment given to injured person before doctor arrives" , "Initial treatment for injured person before doctor arrives" , "medical attention" , "Preliminary medical help pending arrival of doctor" .)
