Ullrich TL, et al. – The researchers undertook this work to explore the effects of nasal high-frequency oscillatory ventilation (nHFOV) settings on oropharyngeal gas conditions. They indicated that intensified nHFOV settings with low frequencies, high amplitudes, and high inspiratory-to-expiratory (I:E) ratios might place infants at an increased risk of upper airway desiccation. Hence, further research work was needed to develop strategies to optimize heated humidification during nHFOV.
