What outcome might suggest a worsening condition in a patient with asthma?

A decrease in peak flow measurements is a significant indicator of a worsening condition in a patient with asthma. Peak flow meters are simple devices that measure how well air moves out of the lungs, providing a practical way for patients to monitor their lung function at home. A drop in these measurements can signal that the airways are becoming more constricted, which is often a precursor to an asthma exacerbation. Therefore, consistent monitoring showing a decline can prompt earlier intervention and management of symptoms, helping to prevent severe episodes.

In contrast, an increase in peak flow measurements typically indicates improved airflow and better control of asthma symptoms. Stable serum IgE levels may suggest that there is no change in allergic sensitization, but they do not directly indicate control of asthma or worsening condition. A decrease in eosinophil count may correlate with a reduction in airway inflammation, which is generally favorable and suggests better control of the asthma rather than a worsening state.
