Pulmonary Air Flow Analysis
The Pulmonary Air Flow analysis is part of a suite of three automated respiration routines that are included in AcqKnowledge®. The other two are Compliance and Resistance and Full Body Plethysmograph – Penh. Each routine provides breath-by-breath analysis, event marking and exporting of the values to excel.

Pulmonary Airflow
The pulmonary airflow analysis uses a calibrated airflow signal from a pneumotach transducer. The analysis will work with animal or human data. The routine will operate from an existing volume signal or will create a volume signal from the flow data. The system requires a user threshold so that it can identify each respiratory cycle. The software will provide the following measures. Extract basic parameters from a calibrated airflow signal, such as would be recorded using BIOPAC’s pneumotach or airflow transducers. Measures include inspire start, expire start, tidal volume and apnea threshold.
Name | Abbrev. | Description | Units |
---|---|---|---|
Cycle | Index of the exhalation cycle in the data, beginning at 1. | ||
Time | Starting time of the exhale for the cycle. This is the location of the Exhale Start event. | Seconds | |
Peak inspiratory flow | PIF | Maximum absolute airflow occurring in the inspiration cycle immediately preceding the exhalation cycle. This measure is recorded as an interval, so its value is always positive. | Airflow channel units |
Peak expiratory flow | PEF | Maximum airflow during the exhalation cycle being examined. | Airflow channel units |
Tidal volume | TV | Total volume of air inhaled during the breath. | liters |
Minute volume | MV | Volume of air that would be inspired during a minute given the tidal volume and breathing rate of this breath. | liters / minute |
Breaths per minute | BPM | Breathing rate for the breath. | BPM |
Inspiration time | IT | Time interval between the start of inhale and the start of exhale in the breath. | seconds |
Exhalation time | ET | Time interval between the start of exhale and either: start of apnea (if apnea present) start of subsequent breath (if no apnea present) |
seconds |
Total breath time | TT | Time interval between the start of inhale and the start of inhale of the following breath. This is the sum of the inhalation time, exhalation time, and apnea time. | seconds |
Apnea time | AT | Time after end of exhalation where the airflow signal remained within the apnea threshold defined at the start of the analysis. | seconds |
