TrueFlow

Spirometry has never been easier

TrueFlow developed by ndd is the new revolutionary way of directly measuring flow of inhaled and exhaled breath without the need for a mechanical sensor. The benefits to the users by applying ndd TrueFlow and spirette™ are striking and with major impact to practical application of spirometry:
- no contamination of measuring sensor, no cleaning
- no cross contamination of patients
- no calibration
- no variables need to be input (temperature, humidity, pressure)
- no maintenance of any kind
- measuring accuracy like big lab instruments

The first EasyOne product was introduced to market in 2000 and has rapidly become market leader in the countries where ndd is actively marketing its products: USA, Switzerland, Germany, Australia, New Zealand.

EasyOne is quickly becoming the new standard worldwide for all type of spirometry, particularly:
- screening,
- office,
- studies,
- home monitoring,
- laboratory back up,
- point of care testing,
- bedside monitoring

Most famously EasyOne is the spirometer required to be used for all BOLD studies worldwide.

The TrueFlow measurement technology is also available for and used by OEM customers.

MolMass (Molar Mass)

MolMass is measured by utilizing the same technology and hardware as used for TrueFlow measurement based on speed of sound.

MolMass allows direct determination of gas concentrations under certain defined conditions. Some of the most popular applications are:
- Helium and CO determination in DLCO measurements by ndd
- N₂ determination in FRC measurement by ndd
- CO₂ measurement in the UPG application by ndd

MolMass is the second major step introduced by ndd further changing lung function testing drastically. MolMass will allow an expansion of parameters to be measured with the same ndd advantages:
- no contamination no cleaning
- no cross contamination
- no calibration
- no variables need to be input (temperature, humidity, pressure)

MolMass together with TrueFlow are applied in the EasyOne PRO series of instruments to be launched in 2006 for: determination of
- DLCO
- FRC
- other parameters

The EasyOne Pro series is a portable, maintenance free system that allows POCT, bedside and other ambulant applications; outside the confinement of the lung testing laboratories.

MolMass is also available for OEM customers.

UPG (Ultrasound Pneumography)

Lung function testing in a new age; opening the way for new dimensions

ndd has developed the UPG method of measurements for diagnosis of lung conditions applying TrueFlow and MolMass.

UPG is used in screening devices as well as for high end differentiation of lungs conditions of different kinds for example Asthma, COPD and Emphysema

UPG is measured under normal breathing conditions and free of the difficult to coach patient cooperation as required for spirometry.

UPG is the subject of international evaluations being presented at major respiratory events such as ATS, ERS etc. by recognized opinion leaders including Robert Crapo, Robert Jensen, Yoshinosuke Fukuchi, Michael Goldman, Monika Gappa, Heinrich Worth etc.

The application of UPG is already realized in the ndd EasyOne UPG. EasyOne UPG is being used for broad data collection in different world wide sites, in studies and most importantly in the BOLD studies for the GOLD awareness of COPD programs.
