At one point the pulmonologist tried to put a mask over his face when he was deeply sedated. Jobs ripped it off and mumbled that he hated the design and refused to wear it. Though barely able to speak, he ordered them to bring five different options for the mask and he would pick a design he liked. The doctors looked at Powell, puzzled. She was finally able to distract him so they could put on the mask. He also hated the oxygen monitor they put on his finger. He told them it was ugly and too complex. He suggested ways it could be designed more simply. "He was very attuned to every nuance of the environment and objects around him, and that drained him," Powell recalled.
