Sentence examples for airflow interruption from inspiring English sources
The time constant of the viscoelastic unit determines the decay of the pressure curve after airflow interruption.
The shutter closed within 15 ms. The time of complete airflow interruption was 100 ms. It was triggered 150 ms after the onset of expiration.
The Rint, EI is calculated from the airway opening pressure (time function) signal airway opening pressure Pao(t) as follows: based on the assumption that, during a brief (100 ms) airflow interruption there is equilibration between alveolar pressure (PA) and Pao, the Rint, EI is obtained by dividing the change in pressure by the immediately preceding flow.
Seven airflow interruptions are made on the peak flow of expiration.
Five airflow interruptions are made on the peak flow of expiration, the median MicroRint value together with the flow and pressure curves are displayed.
The airflow interruptions were performed using the Bronchoscreen system (Jaeger, Würzburg, Germany) [ 8], a computerized apparatus with a combined nebulizer-shutter head, which allows the changes in resistance of the respiratory system Rint, EI) to be measured with each breath.
The interrupter technique measures changes in mouth pressure after a brief interruption of airflow at the mouth.
It is based on the principle that the alveolar pressure and mouth pressure equilibrate within a few milliseconds of brief interruption of airflow.
By the sudden interruption of (inspiratory) airflow, the respiratory pressure instantaneously drops by the amount of the resistive pressure fraction (airflow rate immediately preceding flow interruption multiplied by the Newtonian resistance of the respiratory system).
An interruption in scoring.
