NO-free air supply and advanced adaptive flow control to support FeNO measurements in accordance to the ATS/ERS guideline

The DENOX 88 module supplies the required NO free air to the patient to perform exhaled NO tests with the ANALYZER CLD 88 sp. The integrated adaptive flow control enables even pre-school kids to perform the ATS / ERS recommended single breath test. The expiratory flow control of the DENOX 88 may be adapted to custom specific needs (e.g. 20, 100, 300 ml/s).
For non-cooperative patients the instrument offers the multiple breath test. The continuous flow of NO free air reduces the infant’s work of breathing. The selectable continuous flow rate enables the adjustment to the specific needs of infants.

NO free air generation from ambient air
As DENOX 88 filters ambient air to produce NO free air, no gas supply is required to run FeNO tests.

Integrated adaptive flow control
The integrated adaptive flow control enables even pre-school kids to perform the single breath test as recommended by the ATS / ERS.

Wide application range
DENOX 88 is suitable for single and multiple breath testing and can be used on infant (>3 kg), children and adult patients.

Application range: > 3 kg body weight
Exp. flow control: 50 ml/s (standard)
Cont. flow 100, 200, 300 ml/s
Mains voltage: 100 – 240 VAC
Weight: 5.4 kg
Dimensions: 250 x 150 x 280 mm
