MODEL RELEASED. Asthma attack. View of a 9 year old girl holding her chest during an asthma attack. Asthma attacks vary greatly,ranging from mild breathlessness to respiratory failure. The main symptoms are wheezing,a dry cough and a feeling of tightness in the chest. During a severe attack it becomes increasingly difficult to breathe,causing distress and anxiety,and eventually the face may turn blue. Bronchial asthma is of two types: allergic,caused by dust,pollen,hair and air pollutants; and intrinsic asthma with no apparent external cause. Treatment involves the use of bronchodilator drugs to widen the constricted airways of the lungs | |
