Pulmonary Function Testing from infant to adult patients
The EXHALYZER® D offers various lung function tests for infants (>3 kg), children and adult patients. The modular system is easily upgradable and fully compliant with the ATS / ERS recommendations for infant and pediatric pulmonary function testing.
The EXHALYZER D offers the “gold standard” in accuracy for clinical application.
Flexible and upgradable
The EXHALYZER D can be extended with several optional modules. The nitrogen washout bypass system allows the performance of multiple washout tests, while the optional NO measurement module allows the non-invasive detection of lung inflammation (fractional exhaled nitric oxide, FeNO), for example. The instrument works independently of the temperature, humidity or viscosity of the gas.
Wide application range
One system for pulmonary function testing for all patients: From infants to school age children to adults, all age groups can be tested on the EXHALYZER D. In particular, the EXHALYZER D is ideally suited for newborns and infants (>3 kg). The low airflow restriction prevents interference with the infant’s spontaneous breathing. Furthermore, newborns sedation is not required for standard tests. Respiratory conditions can be easily followed up from newborns to adults.
ATS / ERS compliance
The instrument and software are fully compliant to the recent ATS / ERS recommendations for pulmonary function testing and exhaled nitric oxide measurements.
All tests are easily started, executed, recorded and evaluated by the SPIROWARE software. Display options include numerical and graphical data analysis. Respiratory conditions can be monitored over time, from newborn to adult age.
