It su s desease state charcacterised by air flow limitation that is not fully reversible. The airflow limitation is usually both pregressive and associated with an abnormal inflammatory respose if the lung to nozious paticles or gases.


It is characterized by episodic periods of reversible airway narrowing in the presence of aeroallergens, irritant, or exercise. Airway narrowing is due to inflammation, smooth muscle, bronchospasm and increased airway secretions

Cystic Fibrosis

It is diasease which affects the excretory gland of the body. It is dysfunction of pulmonary system in which the thickened pulmonary secretions will narrow or obstruct airways leading to hyperinflation, infections and tissue destruction.

Restrictive lung disease

Group of dieases with results in a difficulty in expamding the lungs and reduction in lung volume The restriction can come from disease of the alveolar parenchyma and /or the pleura, changes in the chest wallor an alteration in the neuromuscular apparatus of the thorax.


Bronchiectasis means abnormal dilatation of the bronchi.Chronic suppurative airway infection with sputum production,progressive scarring and lung damage occur,whatever the cause.

Upper Resp Tract infections

Upper respiratory tract infections (URTIs), such as coryza (the common cold), acute pharyngitis and acute tracheobronchitis, are the most common of all communicable diseases


Pneumonia is as an acute respiratory illness associated with recently developed radiological pulmonary shadowing, which may be segmental, lobar or multilobar.
