Pneumonia is a form of acute respiratory infection that affects the lung parenchyma and oxygenation. When a patient with pneumonia is an<unk> , the mortality rate exceeds by 50% if they are placed into intensive care (ICU). According to Kershaw, C 2008 page 1, "as of 2001, pneumonia was the sixth most common cause of death in the United States".<unk> m increases mortality from pneumonia because of leukopenia, lower white blood cell counts, which leads to a worse infection because white blood cells help fight the bacterial infection, so lower numbers result in a less effective immune response.<unk> s are at an increased risk for infection with tissue-damaging gram-negative pathogens or for the spread of bacteria in the blood.
