      High flow nasal cannulae (HFNC) are small, thin, tapered cannulae used to deliver oxygen or blended oxygen and air at flow rates of > 1 L/min. HFNC can be used to provide high concentrations of oxygen and may deliver positive end-expiratory pressure.
    • A novel ambulatory closed circuit breathing system for use during exercise.

      We describe a unique ambulatory closed circuit for delivering high fractions of inspired oxygen to an exercising user who does not require isolation from their environment. We describe the major components and their function and suggest potential applications for such a circuit. This circuit may benefit patients who are chronically dependant on oxygen, are unable to exercise due to hypoxia, or require oxygen supplementation at high altitude.
    • A randomised crossover study of low-flow air or oxygen via nasal cannulae to prevent desaturation in preterm infants.

      Hensey, Conor C; Hayden, Eoghan; O'Donnell, Colm Patrick Finbarr; Department of Neonatology, The National Maternity Hospital, Dublin, Ireland. (2013-09)
      To compare the efficacy of low-flow oxygen, low-flow air and sham treatment given via nasal cannulae in preventing desaturation (falls in oxygen saturation (SpO2)) in preterm infants.
    • Turn and face the strange - ch..ch..ch..changes to neonatal resuscitation guidelines in the past decade.

      Resuscitation of newborns has been described since ancient times and is among the most commonly performed emergency medical interventions. The International Liaison Committee on Resuscitation first made recommendations on resuscitation in newborns in 1999. Over the last decade, new research and careful review of the available evidence have resulted in substantial changes to these recommendations - in particular, regarding the assessment of colour, giving supplemental oxygen, suctioning infants born through meconium-stained liquor, confirming endotracheal tube position, the use of pulse oximetry, giving CPAP to premature infants, keeping preterm infants warm using polyethylene wrapping and cooling term infants with encephalopathy. This process has also highlighted the paucity of evidence to support much of the care given to infants in the delivery room and the need for research to refine our techniques.
