3.3 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.
Note: Do not use the Patient Filter without the NIOX VERO Nasal
Restrictor.
Note: Use the Patient Filter directly after it has been opened.
Note: The Patient filter and the restrictor is for single patient use only.
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.
