Computerized determination of pneumotachometer
characteristics using a calibrated syringe.
Validation of MedGraphics VO2000 Portable Metabolic Analyzer and a modified Pneumotachometer
. Med Sci Sports Exerc 2004; 36:s222.
Tidal volumes for ventilated infants should be determined with a pneumotachometer
placed at the endotracheal tube.
The airflow is measured with a low dead-space volume pneumotachometer
and a differential pressure transducer.
There were measured power of forced expiration by pneumotachometer
, the bronchi receptor sensitivity threshold to histamine and acetylcholine, nose respiratory function, eosinophile quantity in the peripheral blood and nasal mucose secrete.
Minute ventilation was measured using a pneumotachometer
(Jaeger, Viasys Healthcare, Hoechberg, Germany).
Spirometry tests were performed using a pressure differential pneumotachometer
with a computerized acquisition system (Multispiro WinDX).
measures airflow through a mask that is placed over the patient's mouth and nose.
The participants were asked to come to the department where anthropometric data and cardiovascular variables were recorded which was followed by the recording of lung function values using MEDSPIROR a computerized pneumotachometer
. Results: Runners recorded higher lung function values than rowers.
Pulmonary gas exchange variables: Throughout all trials participants breathed through low resistance variableimpedance pneumotachometer
for the determination of respiratory flow rates and volumes.
The pressure input was measured using a Honeywell 176 PC pressure transducer (Microswitch, USA), and the airway flows were measured using a screen pneumotachometer
coupled to a similar transducer with a matched frequency response.
Canon and co-workers assessed this clinical problem by measuring actual [V.sub.T] delivered to the lungs using a pneumotachometer
placed at the endotracheal tube and found a reduction of actual [V.sub.T] compared with the set [V.sub.T] and with the [V.sub.T] displayed on and measured by the ventilator (displayed [V.sub.T] (8).
