Study Summary
We hypothesize that the nocturnal use of continuous positive airway pressure in adults and children with asthma will decrease airway reactivity.
Primary Outcome
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.
Interventions
- DEVICE SHAM
- DEVICE CPAP-Continuous Positive Airway Pressure
