EXHALYZER® D

Exhalyzer D – Pulmonary Function Testing for neonate, infant, pediatric and adult patients.

Exhalyzer D, a unique system for continuous, simultaneous measurement and display of various pulmonary function parameters even on non cooperative prematures, neonates, pediatrics and adult patients. The combination of flow, volume and pressure measurement with optional modules for: capnography, oximetry, exhaled nitric oxide, FRC/LCI measurements and airway occlusion (lung mechanics) facilitating an integrated assessment of the patient.

The system is capable to perform all lung function test procedures as described in the book «Infant Respiratory Function Testing» (1), Pediatric Pulmonary Function Testing (2) and in the ATS/ERS standards (1). Noninvasive detection of lung inflammation (fractional exhaled NO, FENO test) and there is no sedation required for standard tests

Standard Applications:

  •  Tidal Breathing Analysis
  •  FRC and ventilation inhomogeneity measurements
  •  Lung Clearance Index (LCI) and Slope 3 analysis (SnIII)
  •  Nitrogen Washout FRC measurements
  •  Single occlusion lung mechanics analysis
  •  Capnography and Oximetry
  •  Multiple and single breath FENO analysis

The Exhalyzer D offer various different kind of spirometry test for neontal to adult patients. The modular system is easy upgradeable and fully compliant with the ATS/ERS recommendations for infant/pediatric pulmonary function testing.
