inhale to total lung capacity and then exhale forcefullyto residual volume. Integrate FEF to obtain forcedexpiratory volume (FEV). AcqKnowledge generates thespirometry curve via an X/Y plot of expired volume versusexpired flow. The FEF values can be measured directly onthe spirometry curve at the standard 25%, 50% and 75%volume points. To evaluate FEV, use AcqKnowledge topresent the spirometry curve data as a function of time. Todetermine FEV 0.5 and FEV 1.0 , place time cursors 1/2 secondand one second after the start of expiration, respectively.Volume/Flow Loop RelationshipsEasily compare normal tidal breathing loops to maximumbreathing loops by using the X/Y mode to plot flowversus volume.This graphicalrepresentationclearly indicatesthe subject’sreserve capacityin relation tonormal breathing.AcqKnowledgecan also be usedto automaticallydetermine thebreath-by-breathvolume/flow looparea as a function of time.Automatic Data ReductionPowerful automatic data reduction tools reduce large datafiles into manageable sizes. The data reduction tools canextract a variety of concise measurements from very longdata recordings. For example, it’s possible to extract themean tidal volume from consecutive 30-second periods.Record continuously for short- and long-term studies(24+ hours), or pre-program to record for specific timeperiods and dosing events. Automatically triggerpre-programmed trials to record the data around dosingperiods, 24 hours a day, seven days a week.Animal studies Q35The MP System will interfacewith a variety of pulmonaryfunction chambers to providedetailed on-line analysis ofpulmonary function data. Usethe TSD160 Series pressuretransducers to record plethysmogramchamber pressure. Alarge selection of very lowflow pneumotachs (TSD137Series) covers a wide range ofair flow rates.
