Performing a Test
3.9 FRC Test (
EasyOne Pro™ LAB
only)
Introduction
FRC measurement is based on the nitrogen (N
2
) washout method where N
2
is washed out from the lungs while the patient breathes 100% oxygen. The
test is performed during tidal breathing within the range indicated at
a
3-26). After a (configurable) number of breaths, the measurement starts
automatically or it can be started manually with the
Activate
button.
Note
Before conducting the FRC test, the valve unit must be
attached to the flow sensor (see Fig. 2-7). Furthermore, a new
FRC barriette™
and, if a new patient is tested, a new
spirette™
must be inserted (see
Valve, DLCO barriette™/FRC barriette™ and spirette™"
Before performing the first FRC test, check that the valve unit is
properly attached and that the metal coupling ring of the
motor is tight.
Inform patients that they may experience a feeling of dryness
during inhalation. Also, they will hear oxygen escape during
the washout phase.
You can choose between the following tests:
manual mode
automatic mode.
Additionally, the FRC test linked with SVC is available (
Linked FRC Test with
SVC (online)
), see
No linked SVC
SVC before washout
SVC after washout.
Note
The method recommended by ATS/ERS is the linked SVC test.
No linked SVC
Only a plain FRC washout is performed. If an SVC test has been
performed before, the lung volume parameters, such as TLC,
ERV and RV, will be calculated based on this external SVC test.
