Primary ciliary dyskinesia (PCD) is a rare genetic disorder characterised by progressive sinopulmonary disease, with symptoms starting soon after birth.


However, the diagnosis is often delayed until five years of age due to the high technicity required for a positive diagnosis. A low nasal nitric oxide (nNO) measurement is highly suggestive of the disease; therefore standardisation of its measurement is of paramount importance to guarantee reliable results of this essential first-line diagnostic test.

Educational aims

In this session, we will present the ERS Technical Standard of the measurement of nNO in children. The session will provide all the necessary information for people wishing to develop the measurement of nNO in children suspected of PCD. It will also give tools on how to express and interpret results.


  • Describe the different techniques and methods used to measure nNO in children, their advantages and disadvantages.
  • Explain the effect of the environment on nNO measurement and how to deal with it.
  • Propose a standard report and explain how to interpret the results.

Target audience:

  • Clinicians
  • Laboratory technicians
  • Nurses performing the test
  • Respiratory scientists


This webinar will include 45-minute of lectures, followed by a final round table discussion for 15 minutes.

Learning outcomes

After following this webinar, participants should be able to:

  • Set-up the measurement of nNO in their centre
  • Perform nNO measurement in children from the age of one year
  • Report and interpret the results

CME credit

An application for accreditation of this webinar has been made to the European Board for Accreditation in Pneumology (EBAP) for 1 CME credit per 1-hour attendance. If accredited, the CME credit will be granted upon attendance of at least 60 minutes during the live webinar only.

What is a webinar?

A webinar closely simulates a lecture-based teaching experience. The speaker can interact with the audience, just as in a classroom setting. During the webinar, you will be asked to share your opinion on issues related to the topic using interactive polls.

All participants will be able to hear the lecturer and see the slides throughout the presentation. As a participant you will be able to pose questions or discuss ideas with the other participants via the text chat facility and the speaker will respond to the questions via the microphone.
