About me

  • Adjunct Professor of Neonatology at the Department of Women’s and
    Children’s Health from May 1, 2020.
    Primary position: Senior physician at Astrid Lindgren Children’s Hospital.


  • Baldvin Jónsson is a neonatal physician who is engaged in research focusing
    on improving the care for premature babies. Since the 1990s, he has been
    studying bronchopulmonary dysplasia (BPD) – a form of chronic lung disease
    resulting from damage to the lungs that often afflicts premature babies who
    have received respiratory assistance. In Sweden, 300-400 children are born
    extremely preterm each year, of whom about 40 percent suffer from BPD.
    Jónsson has been involved in systematically assessing the basic mechanisms
    of the disease: how overpressure and level of oxygen content causes an
    inflammation in the immature lung that interferes with its development.
    He has also evaluated how harmful various existing technologies for
    respiratory assistance are, plus in recent years been involved in developing
    a new, less intrusive, technology, referred to as rPAP. An international
    randomised study evaluating rPAP has just been concluded and the results are
    expected to be released within a few months. Jónsson is now preparing for
    longterm follow-ups of older children – and possibly young adults – who
    have had BPD.
