Simultaneous versus video counting of coughs in hypertonic cough challenges.

ABSTRACT:

Background

The coughs occurring during cough provocation tests are usually counted at the same time when the test is being conducted, i.e., simultaneously. It is unknown whether cough counting from video recording might increase the accuracy of the cough counting. During recent years, cough challenges with hypertonic aerosols have been introduced. They often provoke very frequent coughing which may complicate the simultaneous cough counting.

Objective

To assess whether cough counting from video recording is superior to simultaneous cough counting in two different hypertonic cough challenges.

Methods

The analysis includes 82 hypertonic saline challenges performed on 66 subjects, providing 1984 observation minutes with both simultaneous and video cough counting. The cou
