Bronchitis

Bronchitis is a respiratory disease (lower) which mucus membranes in the lungs bronchial passages become inflamed.

Bronch-ITIS: inflammation

in bronchial tubes

What is it?

Caused by viral infections, bacteria, or other particles hat irritate the bronchial tubes.

There are many types of viruses and bacteria that causes bronchitis:

• H. Influenzae

• H. parainluenzae

• S. Pneumoniae

Etiology

S. Pneumoniae

• Gram positive

• Slightly pointed cocci

Main virus

What is a virus?• an infective

agent that typically

consists of a nucleic acid

molecule in a protein coat

When does it commonly occur?

• Winter

• Western part of U.S

Why the western part?

• Because those are where it is mostly populated which causes smog and other irritants in the air which will cause the bronchitis.

Statistics:

• Incidence (annual) of Acute Bronchitis: 4.6 per 100 (NHIS96: acute bronchitis); 14.2 million cases annually

• Incidence Rate: approx. 1 in 21 or 4.60% or 12.5 million people in USA

Epidemiology

There are 2 forms of bronchitis:

• Acute ( last from 1-3 weeks)

• Chronic (last 3 moths of the year to 2 years)

Forms

• Responsible for a hacking cough and phlegm production that accompany an upper respiratory infection. Caused by viruses from influenza.

Acute bronchitis

C.O.P.D. = Chronic Obstructive Pulmonary Disease is the result

• Mainly caused by smoking tobacco

Chronic Bronchitis

58 year old male smoker

with moderate C.O.P.D

• Smokers

• Second hand smoking

• Weakened immune system

• Elderly and infants

• GERD (gastro esophageal

• reflux disease)

• Exposure to irritants

Who?

Acid reflux irritates the airways and lungs, which affects breathing and may make people more sensitive to outside conditions such as air pollution, cigarette smoke, and cold air.

This is only for Acute

bronchitis

GERD and Bronchitis

• Cough

• Production of colored mucus

• Fatigue

• Shortness of breath

• Slight fever/ chills

• Chest discomfort

Symptoms for Chronic and Acute

Risk Factors for Acute and Chronic• Smoking• Low resistance• Exposure to irritants• Gastric reflux

• Air borne particles

• Escalation of the flu or cold

• Physical contact with infected surface or person

Transmission

• Chest x-ray

• Sputum test (test mucus)

• Pulmonary function test

Tests and Diagnosis

• Antibiotics (only if doctor suspects bacterial infection)

• Cough medicine

• inhaler

Treatments

• Avoid cigarette smoking

• Get the Flu vaccine

• Wash hands wear surgical mask (if exposed to irritants at curtain jobs)
