What is the pathophysiology of pneumonia?

The development of pneumonia requires that a pathogen reach the alveoli and that the host defenses are overwhelmed by microorganism virulence or by the inoculum size. The endogenous sources of microorganisms are nasal carriers, sinusitis, oropharynx, gastric, or tracheal colonization, and hematogenous spread.

What causes pneumonia in children’s?

Most cases of pneumonia are caused by common viruses that cause cold, flu and other respiratory infections such as adenovirus, rhinovirus, influenza (flu), respiratory syncytial virus (RSV) and parainfluenza virus.

What is the pathophysiology of lobar pneumonia?

Lobar Pneumonia

Congestion: This stage is characterized by grossly heavy and boggy appearing lung tissue, diffuse congestion, vascular engorgement, and the accumulation of alveolar fluid rich in infective organisms. There are few red blood cells (RBC) and neutrophils at this stage.

What is pneumonia in pediatrics?

Pneumonia is a lung infection. It is usually caused by a virus or bacteria. These germs make the air sacs in the lungs fill with fluid (phlegm or mucous) (Picture 1). This makes it hard to breathe and causes your child to cough.

What is pathophysiology example?

Pathophysiology: Deranged function in an individual or an organ due to a disease. For example, a pathophysiologic alteration is a change in function as distinguished from a structural defect.

What are the four pathological stages of pneumonia?

Stage 1: Congestion. Stage 2: Red hepatization. Stage 3: Grey hepatization. Stage 4: Resolution.

What are the 3 major causes of pneumonia?

Viruses, bacteria, and fungi can all cause pneumonia.

What are the 4 stages of pneumonia symptoms?

Stages of Pneumonia

• Stage 1: Congestion. During the congestion phase, the lungs become very heavy and congested due to infectious fluid that has accumulated in the air sacs.
• Stage 2: Red hepatization.
• Stage 3: Gray hepatization.
• Stage 4: Resolution.

What are the 4 components of pathophysiology?

Pathophysiology includes four interrelated topics: etiology, pathogenesis, clinical manifestations, and treatment implications. Etiology refers to study of the proposed cause or causes of a particular disease process.
