Body Plethysmograph Measurements Before and After Methacholine Challenge in Early Childhood
In our previous study of Methacholine Challenge Tests (MCT) in preschool children, we found that wheeze detection was associated with significant reduction in flows and vital capacity values. We hypothesized that this finding is associated with trapped-air rather than the children's loss of cooperation/concentration.
Objectives: To test this hypothesis by attempting plethysmography measurements during MCT.
