The document discusses respiratory diseases, outlining their classification into infectious diseases, obstructive lung diseases, and chronic obstructive pulmonary disease (COPD). It presents the prevalence of various respiratory conditions, their etiologies, diagnostic tools, and treatment options, including medications for conditions like asthma, tuberculosis, and lung cancer. The document also highlights symptoms, types of cough, and common viral infections such as the common cold and swine flu.

2. Introduction
Pathological condition that
affects the organs and
tissue that helps in gas
exchange.
 Affected organs like
Trachea, Bronchi,
Bronchioles, Alveoli, Lungs
& muscles of breathing.
Study of respiratory disease
is also known as
Pulmonology.

3. Classification of disease

• Pneumonia
• Cough

o Lung Cancer
o Asthma
 Chronic Obstructive Pulmonary Disease (COPD)
o Emphysema
o Bronchitis

mediators called
prostaglandins(co

stimulating the ᾳ-
adrenergic
receptor causes

mucus gland
secretion.

function

22. Diagnostic tools:
• Nasopharyngeal swab for viral culture
• The gold standard test
• Rapid immune fluorescence test
• Viral culture
