Often catch cold, fatigue, and other incentives or with chronic obstructive pulmonary disease, heart failure, and other underlying diseases and one-third of patients with premorbid history of upper respiratory tract infection. Majority of onset hurry. Gram-negative bacilli pneumonia, elderly pneumonia, nosocomial pneumonia onset occult. The fever is common, mostly sustained high fever, after antibiotic treatment from time typical hot type. Cough, expectoration many the early dry cough, gradual expectoration, sputum volume number of different. Sputum showed mostly purulent sputum Staphylococcus aureus pneumonia typical yellow purulent; Streptococcus pneumoniae pneumonia rusty sputum; pneumoniae pneumonia brick red sticky frozen samples; Pseudomonas aeruginosa pneumonia pale green; anaerobes infection is often accompanied by the smell. Developed antimicrobial therapy to the typical the sputum performance has been rare. Hemoptysis rare. Part of the chest pain was lancinating pain involving the pleura. The diaphragmatic pleura lower lobe pneumonia stimulation, pain may radiate to the shoulder or abdomen, which is often misdiagnosed as acute abdomen. Systemic symptoms of gastrointestinal symptoms such as nausea, vomiting, abdominal distension, diarrhea, headache, muscle aches, fatigue, a few.

The small number of shock (sudden drop in blood pressure within 24 hours to 10.6/6.7kPa undetectable even with irritability, pale limbs Jueleng, oliguria, tachycardia, and weakened heart sounds), more common in the elderly. Streptococcus pneumoniae pneumonia often accompanied lips herpes simplex. Early chest signs no abnormal findings or only a small amount of moist rales. With the development of the disease, becoming the typical signs. Ipsilateral breathing exercise unilateral pneumonia may have weakened the percussion sound cloud, reduce breath sounds and moist rales. Consolidation signs often suggestive of a bacterial infection. Pneumonia in the elderly, Gram-negative bacilli pneumonia and chronic bronchitis secondary to pneumonia, more than at the same time involving bilateral the examination back two lungs moist rales.
The total number of white blood cells and neutrophils increased. Frail elderly persons from time increased white blood cell count is still high, but the percentage of neutrophils. Lung inflammation significantly but not elevated white blood cell count is often prompted a serious condition. Often show decreased arterial oxygen tension.
