Machine type, environmental factors, respiratory manoeuvres and report interpretation are fundamental considerations when performing nNO testing. A European Respiratory Society Task Force recently published standards for testing which we summarise and discuss in this article. There are two main types of nNO machines: chemiluminescence and electrochemical analysers. Chemiluminescence analysers are highly accurate, reliable, real-time and have been validated in multicentre studies but are less portable and more expensive to purchase and maintain in comparison to electrochemical devices. Several factors may influence nNO levels and need to be addressed during patient preparation for testing. Factors including acute viral infections and nose bleeds may contribute to falsely low nNO levels, whereas high ambient NO levels may falsely increase nNO. Tidal breathing, breath-hold and exhalation against resistance are the three main respiratory manoeuvres used in nNO sampling and require a minimal, modest and high level of patient cooperation respectively. Finally, standardised reporting of nNO testing and the correct interpretation helps clinicians to formulate an appropriate clinical plan towards an accurate PCD diagnosis.</p>","PeriodicalId":9292,"journal":{"name":"Breathe","volume":"21 2","pages":"240230"},"PeriodicalIF":2.3,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12171850/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SARD-ILD significantly impacts morbidity and mortality, with disease manifestations ranging from mild to severe and life-threatening. Epidemiological data show varying ILD prevalence rates amongst SARDs, with fibrosis being a key pathological component secondary to immune-mediated inflammation and tissue remodelling.

Diagnosis relies on a comprehensive evaluation of clinical, serological, radiological and histological data, involving a multidisciplinary team. Immunosuppressive therapy is the cornerstone of treatment, with concurrent use of anti-fibrotic agents in specific progressive cases. Disease management is stratified by severity, with distinct guidelines for stable, progressive and rapidly progressive ILD.
