4.3.1 Expiration against Resistance (ER-nNO)
ER-nNO Nasal measurements shall be performed while exhaling through
the mouth towards a restrictor (breathing handle), this generates a pressure
that makes sure the velum is closed. The NIOX VERO Breathing Handle with
a patient filter and the NIOX VERO restrictor is used as the restrictor in this
breathing method. The breathing handle is NOT connected to the
NIOX VERO when used in this manner.
1. Open a new Patient Filter and insert an new Nasal Restrictor into the
Patient Filter, so that it rests on top of the white filter pad.
2. Attach the Patient Filter to the Breathing Handle until it clicks into place
3. Give the breathing handle to the patient, put the Olive to the selected
nostril and instruct the patient to inhale to total lung capacity and to begin
exhaling into the patient filter once their lips are tightly sealed around it.
The patient will have to exhale steadily and continuously for 30 seconds.
4. Select start measurement button (A) to start a ER-nNO Nasal
measurement with NIOX Panel.
Note: If measurement is started before patient is ready, there is an option
to abort measurement, it is not recorded as a measurement on
sensor or instrument.
Note: The y-axis does not show a nitric oxide value during the
measurement and analysis periods. This is due to the entire sample
having to cycle through the sensor (delayed analysis).
5. The instrument will aspirate for 30 seconds and then will start to analyze
the sample. After the aspiration is complete, remove nasal olive from the
nostril and wait for the result.
Note: By selecting the abort button (A) the measurement is canceled. This
can be pressed in the measurement or analysis period to abort the
measurement.
