![Page 2: Brittany Skaehill, Julian Rulan, Maryna Ugalde, & Katlyn Feick](https://reader036.vdocument.in/reader036/viewer/2022062516/56649db55503460f94aa72f6/html5/thumbnails/2.jpg)
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?
![Page 3: Brittany Skaehill, Julian Rulan, Maryna Ugalde, & Katlyn Feick](https://reader036.vdocument.in/reader036/viewer/2022062516/56649db55503460f94aa72f6/html5/thumbnails/3.jpg)
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
![Page 4: Brittany Skaehill, Julian Rulan, Maryna Ugalde, & Katlyn Feick](https://reader036.vdocument.in/reader036/viewer/2022062516/56649db55503460f94aa72f6/html5/thumbnails/4.jpg)
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
![Page 5: Brittany Skaehill, Julian Rulan, Maryna Ugalde, & Katlyn Feick](https://reader036.vdocument.in/reader036/viewer/2022062516/56649db55503460f94aa72f6/html5/thumbnails/5.jpg)
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
![Page 6: Brittany Skaehill, Julian Rulan, Maryna Ugalde, & Katlyn Feick](https://reader036.vdocument.in/reader036/viewer/2022062516/56649db55503460f94aa72f6/html5/thumbnails/6.jpg)
There are 2 forms of bronchitis:
• Acute ( last from 1-3 weeks)
• Chronic (last 3 moths of the year to 2 years)
Forms
![Page 7: Brittany Skaehill, Julian Rulan, Maryna Ugalde, & Katlyn Feick](https://reader036.vdocument.in/reader036/viewer/2022062516/56649db55503460f94aa72f6/html5/thumbnails/7.jpg)
• Responsible for a hacking cough and phlegm production that accompany an upper respiratory infection. Caused by viruses from influenza.
Acute bronchitis
![Page 8: Brittany Skaehill, Julian Rulan, Maryna Ugalde, & Katlyn Feick](https://reader036.vdocument.in/reader036/viewer/2022062516/56649db55503460f94aa72f6/html5/thumbnails/8.jpg)
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?
![Page 10: Brittany Skaehill, Julian Rulan, Maryna Ugalde, & Katlyn Feick](https://reader036.vdocument.in/reader036/viewer/2022062516/56649db55503460f94aa72f6/html5/thumbnails/10.jpg)
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
![Page 14: Brittany Skaehill, Julian Rulan, Maryna Ugalde, & Katlyn Feick](https://reader036.vdocument.in/reader036/viewer/2022062516/56649db55503460f94aa72f6/html5/thumbnails/14.jpg)
• 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)
