Preferred Label : Interrupter Technique;
NCIt related terms : RINT;
NCIt definition : A non-invasive method of measuring airway resistance during which the subject breathes
normally while airflow is interrupted at a predetermined rate and volume during the
early exhalation phase. Airway resistance is calculated as the ratio of alveolar pressure,
which is estimated from mouth pressure during occlusion, to airflow before interruption.
This method is used most often in children and other subjects unable to comply with
instructions for conventional lung function tests.;
Alternative definition : CDISC: A non-invasive method of measuring airway resistance during which the subject
