    Investigation of lung volume measurements in neonates using gas in scattering media absorption spectroscopy
    (Optica Publishing Group, 2022-04) Pacheco, Andrea; Jayet, Bapiste; Grygoryev, Konstantin; Messina, Walter; Dehghani, Hamid; Krite Svanberh, Emilie; Dempsey, Eugene M.; Andersson-Engels, Stefan; Science Foundation Ireland
    We perform phantom and numerical studies of the changes in molecular oxygen and water vapor spectroscopic signals, showing the potential of measuring pulmonary volume changes with GASMAS technique in neonates.

    Non-invasive lung oxygen monitoring in term infants: a pilot trial
    (Optica Publishing Group, 2022-04) Panaviene, Jurate; Grygoryev, Konstantin; Pacheco, Andrea; Dempsey, Eugene M.; Andersson-Engels, Stefan; Science Foundation Ireland
    Employing non-invasive GASMAS based system, lung oxygen measurements were performed on 25 healthy term infants on various chest positions. Oxygen and water vapor absorption signal was detected on most occasions.

    Heart rate variability during periods of low blood pressure as a predictor of short-term outcome in preterms
    (Institute of Electrical and Electronics Engineers (IEEE), 2018-10-29) Semenova, Oksana; Carra, Giorgia; Lightbody, Gordon; Boylan, Geraldine B.; Dempsey, Eugene M.; Temko, Andriy; Science Foundation Ireland
    Efficient management of low blood pressure (BP) in preterm neonates remains challenging with a considerable variability in clinical practice. The ability to assess preterm wellbeing during episodes of low BP will help to decide when and whether hypotension treatment should be initiated. This work aims to investigate the relationship between heart rate variability (HRV), BP and the short-term neurological outcome in preterm infants less than 32 weeks gestational age (GA). The predictive power of common HRV features with respect to the outcome is assessed and shown to improve when HRV is observed during episodes of low mean arterial pressure (MAP) - with a single best feature leading to an AUC of 0.87. Combining multiple features with a boosted decision tree classifier achieves an AUC of 0.97. The work presents a promising step towards the use of multimodal data in building an objective decision support tool for clinical prediction of short-term outcome in preterms who suffer episodes of low BP.
