EasyOne Pro™ / EasyOne Pro™ LAB 15
Introduction
1.7 Intended Use
The ndd EasyOne Pro™ Respiratory Analysis System is designed for con-
ducting lung function measurements in general or specialist practices or in
hospitals.
The EasyOne Pro™ Respiratory Analysis System can also be used outside of
the laboratory when performing lung function screenings or measurements
in occupational medicine.
The EasyOne Pro™ Respiratory Analysis System is used to conduct lung
function measurements on adults and children starting at age 4, except
measurements of Diffusing Capacity of the lung based on CO (DLCO), which
can be performed on adults and children starting at age 6.
1.8 Contraindications to Performing DLCO Tests
Do not perform a DLCO test

in the presence of carbon monoxide toxicity

in case of dangerous levels of oxyhemoglobin desaturation without
supplemental oxygen
1.9 Additional Functions of EasyOne Pro™ LAB
EasyOne Pro™ LAB includes the measurement of the FRC (Functional Resid-
ual Capacity) based on the Multiple Breath Nitrogen (N
2
) Washout method.
This method is based on washing out the N
2
from the lungs, while the
patient breathes 100% oxygen. The analysis of the expired N
2
trace is used
to compute the FRC and other parameters like LCI (Lung Clearance Index)
that are used to quantify distribution inhomogeneities of the lung. The test
is based on tidal breathing only and can easily be performed in adults and
children starting at age 4.
