Chemical pneumonia is an unusual type of lung irritation. In chemical pneumonia, inflammation of lung tissue is from poisons or toxins. Pneumonia is part of the overall infection, and signs of pneumonia include high fever, a relatively slow heart rate, diarrhea, nausea, vomiting, and chest pain. Pneumonia in patients in nursing homes and long-term care facilities has been associated with greater mortality than in patients with Community-acquired pneumonia.
Physical examination may sometimes reveal low blood pressure, a high heart rate, or a lowoxygen saturation. Elderly or very sick patients may need longer treatment. . Atypical pneumonia is most commonly caused by mycoplasma, Legionnaires’ disease, or chlamydia and usually appears in children and young adults. The safety of the pneumococcus vaccine for pregnant women has not yet been studied.
