WHAT IS BRONCHITIS?


CikguOnline
CikguOnline








Bronchi











Definition of Bronchitis










• Inflammation of the breathing tubes
within the lungs (bronchial tubes or
bronchi) as a result of an infection
(viral or bacterial) or a chemical

irritant (such as smoke or gastric
acid reflux).





• Person will end up with cough and
mucus.


CikguOnline
CikguOnline



Type of Bronchitis









1. Acute bronchitis








• The inflammation causes swelling of the lining of these breathing

tubes, narrowing the tubes and promoting secretion of inflammatory


fluid.



• Most commonly, acute bronchitis is due to a viral infection.



• Acute bronchitis may also be called a chest cold.

PATHOPHYSIOLOGY




BRONCHITIS


CikguOnline
CikguOnline
Bronchitis Pathogenesis








Etiologic factor



Phagocyte migration, proinflammatory mediators releasing

(cytokines, enzymes), their storage in mucous membrane








Respiratory tract mucous Vessel reaction

membrane direct - Vasodilation

impairment

Increased permeability of vessel wall




Exudation




Mucous membrane oedema




Bronchial hypersecretion due to irritation and

dilation of goblet cells


CikguOnline
CikguOnline



Pathophysiology Bronchitis










Irritant Mucus-secreting glands and Ciliary function
goblet cells increase excess decreases


mucus production









Bronchiol lumen Bronchiol wall muscles A lot of mucus


narrowing thicken collection














Bronchioles damaged Bronchitis

and fibrosed

Etiology of Bronchitis









3. Air pollution including cigarette smoke, chemical fumes and dust

are often the cause of chronic bronchitis.








All these conditions will cause irritation and then inflammation of the


airways

CLINICAL




MANIFESTATIONS

CikguOnline



Clinical Manifestations of Bronchitis







1. Acute bronchitis 2. Chronic bronchitis

• Persistent coughing and sputum
• The cough contains little or no


phlegm production that is getting worse and


worse throughout the day and night.
• Mild fever (less than 38.3 ° C)

Usually the cough gets worse in the
• Dyspnoea

morning
• tachycardia

• Difficulty breathing and chest tightness

• Sore throat
• Sometimes it sounds ronchi


• Muscle pain
(auscultation) / wheezing


• Fatigue • Disruption during activities such as



exercise 21

2. Radiology



• C X R to see the condition of the lungs.








3. Lab test



• TWBC - Leucocytosis (increase in the number of leukocytes in the


blood)



• ESR (erythrocyte sedimentation rate) to see the erythrocyte

sedimentation rate

Assessment of Bronchitis Patients









• Sputum C + S (sputum culture and sensitivity)-to determine effective

micro-organisms and drugs.








• Arterial Blood Gas (ABG) - assesses the status of oxygen and carbon


dioxide in the blood

Assessment of Bronchitis Patients






4. Lung Function Test



• test uses spirometry



• to assess lung function



• Vital capacity - the volume of air that can be inhaled into the lungs


during maximum inspiration followed by maximum expiration time

(4.8 litres)



• Tidal Volume - the volume of air inhaled and exhaled in one breath of


0.5 liters.



• Residual volume - the volume of gas in the lungs at the end of the


maximum exhalation of 1.2 liters.
