The blue inhaler, commonly known as a reliever inhaler, is instrumental in treating asthma by quickly delivering medication to relax the muscles around the airways, thus easing breathing during an asthma attack. This immediate relief is crucial for individuals experiencing sudden symptoms. Additionally, for asthma patients who also experience swelling or discomfort due to associated conditions like arthritis, using supportive devices such as ankle and wrist cuffs can help manage joint pain and improve mobility, complementing the overall treatment and enhancing quality of life.
