Ponemah PULMODYN is a comprehensive data acquisition and analysis platform for all your respiratory study needs. Primary respiratory airflow and airway, thoracic or esophageal pressure and hemodynamic signals are acquired using one of several available data acquisition hardware setups. PULMODYN derives secondary signals (e.g. tidal volume) in real time from the primary signals. Data visualization, analysis and reporting features, saved acquisition and analysis protocols allow you to rapidly go from data collection to visualization and analysis.

dT(only AWR) The delay , in milliseconds, between the mouth and chest volumes.
PEnh Enhanced Pause.
RT Relaxation Time. This is the time from the start of expiration to the point where the volume signal drops by the Percent Relaxation value from its maximum value for the cycle.
TVe This is the difference between the volume at the start expiration mark and the volume at the point prior to the next cycles start inspiration mark. It is always reported in milliliters.
IF50 IF50 reports the inspiratory flow value at the point where the volume signal rises to 50% of the tidal volume.
EF50 EF50 reports the expiratory flow value at the point where the volume signal drops to 50% of the tidal volume.
