Severe asthmatic episode that does not respond to normal treatment.
An attack of bronchial asthma which lasts for a long time and results in exhaustion and collapse.
Prolonged, severe asthma attack in which spasm of the bronchi does not respond to standard treatments. Cyanosis (bluish discoloration of the skin) and other signs of lack of oxygen may occur, along with respiratory failure. Treatment involves aggressive bronchodilator therapy, corticosteroids, and possibly artificial respiration.
A prolonged, extremely severe, life-threatening asthma attack.
An intense and continuous asthmatic state. Status asthmaticus does not respond to the usual treatments for asthma and can produce severe shortness of breath that results in exhaustion and collapse. This extreme asthmatic state, which has become increasingly prevalent in children, requires immediate and aggressive treatment.
An attack of asthma lasting for more than 24 hours. This causes great distress and there is a risk of death from respiratory failure or exhaustion. Treatment with corticosteroid drugs may be life-saving and artificial respiration may be needed. Sedation is risky, and these cases require skilled care.
Nowadays more usually termed acute severe asthma, this is a prolonged period of wheezing and shortness of breath with little or no respite between the spasms, usually lasting for more than 24 hours. The patient is seriously distressed and, untreated, the condition may lead to hypoxia and exhaustion. Continuous or very frequent use of nebulized bronchodilators, intravenous corticosteroid treatment, and other skilled medical care are urgently required, including availability of assisted or artificial ventilation.
An intense and extended episode of asthma. This state carries the potential risk of being life-threatening and requires immediate medical intervention.
Frequent bouts of asthma or an extended asthmatic episode that doesn’t improve with treatment, leading to the patient’s overall health declining.
