As Scaletta raced to the front of the store, about 30 feet away, 78-year-old Pete Catlow had already begun turning blue from lack of oxygen. But Scaletta said it took only two sets of chest compressions and mouth to mouth breathing before his color began to normalize. She had completed three sets when paramedics from the nearby Aurora Fire Station 3 arrived --- within minutes, thanks in large part to store clerk Nancy Orbes dialing 911 almost the instant Catlow collapsed.
