Considering Loretta only had the use of one hand as the other was nursing her own injury (hopefully she wouldn't be blind for life!), she left the whole 'move the unconscious body' thing to someone with full range of their senses. But a cooling charm, that she could do. She got out her wand and cast it. Only it did absolutely nothing and room stayed as stifling hot as it had been. She tried another charm that would have the same sort of effect but nothing worked.
