A Jaeger pneumotachograph
(Viasys Healthcare) was used for pulmonary function testing.
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.

Measurements during cycle ergometry tests: Participants breathed through a mouthpiece attached to a pneumotachograph
during each cycle ersgometry test.
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
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.
Participants were connected to a metabolic cart (VMax 229, Sensormedics, Yorba Linda, Calif) which consisted of a pneumotachograph
A drop in minute ventilation of 16% and 32% during non-REM and REM sleep respectively was observed by Becker and coworkers , predominantly due to a decrease in tidal volume as measured by a pneumotachograph
Lung function indices, including the forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC), were measured with a pneumotachograph
The meters tested were mini Wright, Vitalograph, TruZone, MultiSpiro and Pneumotachograph
Briefly, a pneumotachograph
(Model 3800; Hans Rudolph, Kansas City, MO) and transducer (MP45-871; Validyne, Northridge, CA) were attached to a non-rebreathing Y valve (Model 7900; Hans Rudolph), which was connected to a manual valve that allowed switching inspired gases between room air and a bag containing a mixture of [C.
