Final answer:
Patients with asthma typically carry bronchodilators or rescue inhalers to manage sudden asthma attacks by quickly relieving constricted airways, allowing easier breathing.
Step-by-step explanation:
Patients with asthma commonly have bronchodilators or rescue inhalers with them at all times. These medications are especially crucial during an asthma attack, as they work quickly to soothe constricted air passages and help to re-expand them, making breathing easier. Bronchodilators start taking effect almost immediately to relieve symptoms such as coughing, shortness of breath, wheezing, and chest tightness. For long-term control of asthma, corticosteroids are often prescribed, and it's also essential for individuals with asthma to avoid triggers such as environmental factors and allergens that can provoke an attack.
