When a strong virus, bacteria, or fungus gets past the body’s normal defenses and causes an infection in the lungs, the person has pneumonia. Pneumonia that is contracted as you go about your daily life is called community associated pneumonia. People can contract pneumonia in hospitals. Ventilator associated pneumonia is particularly troublesome to treat because the person was already sick before developing the disease. The Centers for Disease Control and Prevention report that 4 out of every 1,000 patients discharged from hospitals have contracted pseudomonas pneumonia during their hospitalization. Pseudomonas accounts for 10.1 % of all infections acquired in hospitals.
The severity of pneumonia determines how aggressive the treatment plan needs to be. The pneumonia severity index calculator allows the doctor to enter data such as a person’s age, gender, whether or not they live in a nursing home, lab tests, alertness, etc. to come up with the severity level. There are five levels. Hospitalization is recommended for levels 4 and 5. This index also provides a percentage of the likelihood that the patient will die. Walking pneumonia symptoms in adults are mild and may be hard to distinguish from the common cold.
The right lung has three lobes, while the left lung has only two. In milder cases, only one lobe may be affected by pneumonia. Multilobar pneumonia is an infection in two or more lobes. If the infection is present in both lungs, the person is said to have double pneumonia. Multilobar pneumonia is serious and needs to be treated as such. Bacterial pneumonia is treated with antibiotics. Viral pneumonia is treated with antiviral medication. Most people with community associated pneumonia can be treated at home. People with serious multilobar pneumonia may need to be treated in a hospital.
A person hospitalized with multilobar pneumonia will probably be given oxygen. The inflammation, fluid and infection make it hard for the lungs to exchange gasses. Doctors will test to see if there is enough oxygen in the blood. The patient may also be given an intravenous form of antibiotics. Patients with chronic conditions or compromised immune systems because of disease or chemotherapy are considered high risk when it comes to pneumonia.
