Pneumonia
Pneumonia is an inflammation of the tissue in one or both lungs, usually caused by a bacterial infection. This chapter begins with a brief background to pneumonia, and then describes three different types of the disease: community-acquired pneumonia, hospital-acquired pneumonia, and aspiration pneumonia. Symptoms are listed, along with a severity assessment. Transmission, risk factors, and treatment are all outlined. Most types of pneumonia can be effectively treated with antibiotics, but it can be a serious illness, especially in frail older people, young people, and those already ill or immunocompromised. In these cases, the mortality rate is between 5% and 14%. Pneumonia can occur at any time of the year, but it is more common in the autumn and winter. Investigations and prevention are also covered, as well as specific nursing care considerations including oxygen therapy.
