The use of fractional exhaled nitric oxide (FeNO)-based asthma management during pregnancy can significantly reduce asthma exacerbations in non-smoking pregnant women. The feasibility of implementing this strategy into antenatal care has not been explored.To examine the feasibility of implementing FeNO-based asthma management into antenatal clinics in New South Wales (NSW) Australia.Semi-structured face-to-face interviews with video elicitation were conducted with healthcare professionals (HCPs) providing antenatal care in one of two hospital-based antenatal clinics in NSW, Australia. The video shown demonstrated the use of the FeNO instrument and other aspects of the management strategy, in antenatal care. Interviews were recorded, transcribed and analysed using qualitative content analysis.A total of 20 interviews were conducted with 15 midwives, four obstetricians, and one general practitioner. Two main themes and ten sub-themes arose: Getting a number (sub-themes: engaging, technically easy, objective, predictive, reassuring); and Resourcing (sub-themes: time and timing, systems, staff, education and cost). Comments included: 'It's easy, fast and effective' and 'the main barrier is time'. All HCPs felt capable of facilitating the FeNO-based management strategy, with appropriate education, and were willing to undertake this strategy, saying: '…it would be perfectly acceptable for a midwife or doctor to do it'; also, 'they don't necessarily need to see a physician, it's something that midwives would take on generally…'.Participants in this study considered FeNO-based asthma management for pregnant women to be a feasible addition to antenatal care following appropriate provision of resources and education.
