Asthma is a chronic disease characterized by recurrent attacks of breathlessness, cough and wheezing which vary in frequency and severity from person to person.
“First sign of disease is ‘persistent cough’. Symptoms may occur several times in a day or week in affected individuals. For some people the symptoms become worse during physical activity or at night. Failure to recognize triggers that lead to a tightened airway can be life threatening and may result in asthma attack, respiratory distress and even death,”
Chronic obstructive pulmonary disease (COPD) is a general name given to a number of conditions including chronic bronchitis and emphysema. The COPD causes the airways in the lungs to become narrower, making it more difficult for the air to move into and out of the lungs.
Respiratory Distress Syndrome or surfactant deficiency disorder (SDD) is a syndrome in premature infants caused by developmental insufficiency of surfactant production and structural immaturity in the lungs. It can also result from a genetic problem with the production of surfactant associated proteins.
