Asthma: the pulse is not the paradox
1Chest Service, Bronx Municipal Hospital Center, New York 10461.
Abstract:
Some interesting, unusual features of asthma are discussed: that patients may be better able to evaluate the severity of their asthma than physicians; that expiratory obstruction indirectly increases the work of inspiration; that 1 of the responses to airflow obstruction is hyperventilation; that localized areas of airflow obstruction may cause increased ventilation/perfusion ratios by decreasing perfusion more than ventilation; that increasing tidal volume may cause a reduction in alveolar ventilation; and, finally, that there is evidence that asthma has worsened in recent years, despite advances in the understanding and treatment of this disease.

Pulse Rate and its Significance
Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls...

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
