Philip Madden suffered from numerous medical conditions including obesity, respiratory acidosis, congestive heart failure, chronic obstructive pulmonary disease, obstructive sleep apnea, obesity hyperventilation syndrome and hyperlipidemia. He was admitted to the Jesse Brown V.A. Medical Hospital in Chicago several times leading up to his last admission in December 2007.
When he returned for an outpatient appointment, it was found that his labs were abnormal. He was admitted to the hospital. At the time of his admission, the pulmonary consulting services described him as suffering from a wide range of medical issues.
Madden was placed in respiratory isolation. A week after being admitted, he suffered a cardiopulmonary arrest. Madden was intubated and resuscitated, but he never regained consciousness and died later at a long-term care facility.
