|Official Title:||Assessment of the Effects of Short and Long Term Use of Continuous Positive Airway Pressure on Airway Reactivity in Children and Adults With and Without Asthma|
|Study Start Date :||February 2005|

Subjects will use CPAP of 8-12 during days 2 through 6 of the study.
Device: CPAP-Continuous Positive Airway Pressure
Cpap will be worn at night by subjects 6 to 7 days duration.
Sham Comparator: SHAM
Subjects will use sham CPAP of 0-2 during days 2 through 6 of the study.
SHAM will be worn at night by subjects 6 to 7 days duration.
- Change in Provocative Concentration of Methacholine Causing a 20% Fall in Forced Expiratory Volume in 1 Second (FEV1) [ Time Frame: 7 to 10 nights after cpap is started. ]Methacholine is an inhaled medication used to assess asthma and reactive airways. It was given at increasing concentrations (beginning with 0.0625 mg/ml and ending with 16.0 mg/ml). Each dose was followed by a lung measurement until a change of FEV1 of 20% occurs or until a maximum dose was reached, whichever came first.
