攻击面广，雷暴天小心这种病发作

Core Viewpoint - The recent surge in emergency room visits in Hebei and Shanxi due to thunderstorm asthma highlights the increasing prevalence of this condition, which is triggered by specific weather conditions and allergens [1][4]. Group 1: Thunderstorm Asthma Overview - Thunderstorm asthma is an acute asthma attack triggered by thunderstorms, particularly affecting individuals with allergic rhinitis or asthma during high pollen seasons [2][3]. - The phenomenon involves the combination of thunderstorms and high concentrations of pollen or mold spores, which can lead to severe respiratory reactions [2][3]. Group 2: Characteristics of Thunderstorm Asthma - Thunderstorm asthma has distinct characteristics compared to regular asthma, including: 1. Explosive onset with a rapid increase in patient numbers, leading to emergency room overcrowding [6]. 2. Higher severity, with rapid onset of bronchospasm and significant drops in blood oxygen levels, requiring urgent medical intervention [7]. 3. Broader attack surface, affecting not only diagnosed asthma patients but also those with pollen allergies or family histories of allergies [8]. 4. Clear and singular triggers, specifically thunderstorms coinciding with high pollen or mold concentrations [9]. 5. Delayed and recurrent risks, with potential for asthma attacks to occur 1 to 3 days after the thunderstorm [10]. Group 3: Prevention Strategies - Identifying at-risk populations is crucial, including individuals with a history of asthma, allergic rhinitis, or those with known pollen allergies [11]. - Awareness of high-risk months is essential, particularly from August to October in northern regions and March to May and July to September in southern regions [11]. - Daily protective measures include monitoring weather and pollen forecasts, minimizing outdoor activities during high pollen periods, and maintaining indoor cleanliness to reduce pollen exposure [12][13]. - For sensitive individuals, using air purifiers and adhering to prescribed medications during thunderstorms is recommended [14]. Group 4: Emergency Response - Immediate use of rescue medications, such as bronchodilators, is critical during an asthma attack triggered by thunderstorms [15]. - Monitoring blood oxygen levels and seeking emergency medical assistance if symptoms do not improve is vital [15].
