Results Overview

This is a measure of forced expiratory volume measured in one second, following the administration of 4 puffs of albuterol. This outcome will compare the change in post-bronchodilator FEV1 (L) both before and after treatment.

PRIMARY outcome

Timeframe: 7 days

Population: Only one subject was enrolled into the intervention, and after taking the first dose of NAC, they experienced excessive bronchospasm thus making them ineligible to continue and complete the study.

This is a measure of forced expiratory volume measured in one second, following the administration of 4 puffs of albuterol. This outcome will compare the change in post-bronchodilator FEV1 (L) both before and after treatment.

SECONDARY outcome

Timeframe: 7 days

Population: Only one subject was enrolled into the intervention, and after taking the first dose of NAC, they experienced excessive bronchospasm thus making them ineligible to continue and complete the study.

The CT Mucus Score describes the number of segments of the lungs that are impacted by mucus. This outcome will compare the change in CT mucus score both at baseline and following each treatment period.
