Cough volume acceleration is difficult to measure clinically as it requires a pneumotachograph and related equipment.
Computerized flexiflow machine with pneumotachograph was used to perform the dynamic PFTs.
Flow was measured with a heated pneumotachograph (Ventrak 1550, Novametrix Company, USA) connected to a differential pressure transducer inserted between the Y-piece of the ventilator circuit and the endotracheal tube.
Breathing patterns were monitored using a Buxco mouse pneumotachograph with a Buxco pressure transducer coupled to automated Iox 2 software (emka TECHNOLOGIES S.
2]) and a pneumotachograph through a 3-liter syringe (Hans Rudolf, Kansas City, Missouri, USA), as recommended by the manufacturer.
the reduction of the mass of the bell and the addition of graphic and timing devices), and the Fleisch pneumotachograph is also widely used in modern commercial analysers.
The inspired and expired air flow were continuously measured with a pneumotachograph (VIP[TM], nSpire Health GmbH, CO, USA) that was calibrated prior to each test with a 1-liter calibration syringe (ZAN 600, nSpire Health, CO, USA).
Expiratory flow-volume curves were recorded by a spirometer with a pneumotachograph sensor (Model ST90, Fukuda Sangyo Co.
Comparison of peak cough flows measured by pneumotachograph and a portable peak flow meter.
Between the ventilator and the proximal end of the ETT, we interposed in succession, a classic breathing circuit (Y-piece), a respiratory filter (heat-and-moisture exchanger), the same as the ones used in clinical settings, and a heated pneumotachograph (Hans-Rudolph Inc.
Reduction in airflow can be measured accurately by having the patient breathe through a tight-fitting mask with an attached pneumotachograph, but is much more commonly assessed non quantitatively by measuring pressure just inside a nostril or carbon dioxide or temperature near the mouth and nose by means of thermistors.
