The most significant indicator of decreased pulmonary ventilation function during an asthma attack

During an asthma exacerbation, air in most alveoli cannot be exhaled normally. Consequently, functional residual capacity (FRC) is the pulmonary function parameter that increases most markedly. Asthma is a respiratory disorder caused by airway obstruction—typically resulting from bronchial inflammation leading to airway narrowing. Asthma management is usually long-term and primarily involves symptomatic treatment with bronchodilators; however, it is equally important to identify and avoid potential triggers to address the underlying cause. It is essential to drink plenty of warm water, avoid spicy or irritating foods, and consume ample fresh vegetables and fruits.
