The AcqKnowledge and BSL PRO software has a sophisticated Integration feature that works both online and offline. The algorithm identifies the start or end of each breath and integrates the signal to provide a volume signal.
The algorithm has an option for subtracting the mean of the airflow signal, which helps to eliminate any drift or offset in the airflow transducer. The software removes the mean on a breath-by-breath basis and stabilizes the baseline before performing the integration. This feature will delay the display of the volume measurement because the integration can’t commence until the end of the breath. The software will allow you to enter a fixed delay interval so that you know the exact delay between the airflow and volume signals. By using a delay calculation channel, you can also delay the original airflow signal by the same time period. This will align both the volume signal and the airflow.
