The World Health Organisation or WHO (2012) defines asthma as a chronic inflammatory disease of the airways characterised by frequent episodes of breathlessness and wheezing.
This difficulty in breathing is caused by the swelling and constricting of the airways.
They also explain that the inflammatory agents such as histamine, tryptase, leukotriences and prostaglandins act on smooth muscles of airway walls and cause bronchoconstriction which restricts the airflow to alveoli.
Brown and Edwards (2012) write that wheezing, breathlessness, chest tightness and cough are the most common clinical manifestations of asthma.
Antibiotics are also helpful as they control respiratory infections that aggravate asthmatic conditions.
In extreme cases mechanical ventilation can be used if the patient does not respond to any of the above therapy.
Exposure to allergens, pollutants, cold air, infection and exercise can increase the risk of asthmatics having an attack (Funnel, Koutoukidis and Lawrence 2009).
This essay will discuss on the pathophysiology, diagnosis, medical management and clinical manifestations of asthma.
It will also cover the client education needed to provide for those with asthma, asthma’s risk factors and its prognosis.
According to the National Asthma Council of Australia or NACA (2006) more than 2.2 million Australians are suffering from asthma.
