BACKGROUND: Respiratory distress syndrome is one of the main causes of mortality in premature neonates. Treatment of these neonates with invasive mechanical ventilation has side effects such as chronic pulmonary diseases. Noninvasive ventilation, such as nasal continuous positive airway pressure (NCPAP) and nasal high-frequency oscillation ventilation (NHFOV), has shown to reduce the burden of chronic lung disease. NHFOV is a promising new mode of noninvasive ventilation and may reduce the need for mechanical ventilation and reduce possible complications...

OBJECTIVE: To compare short-term application of nasal high-frequency oscillatory ventilation (nHFOV) with nasal continuous positive airway pressure (nCPAP). WORKING HYPOTHESIS: nHFOV improves CO2 removal with respect to nCPAP in preterm infants needing noninvasive respiratory support and persistent oxygen supply after the first 72 h of life. STUDY DESIGN: Multicenter non-blinded prospective randomized crossover study. PATIENT SELECTION: Thirty premature infants from eight tertiary neonatal intensive care units, of mean ± SD 26...

BACKGROUND: Invasive mechanical ventilation (IMV) is associated with the development of adverse pulmonary and non-pulmonary outcomes in very premature infants. Various modes of non-invasive respiratory support are increasingly being used to decrease the incidence of bronchopulmonary dysplasia. The aim of this trial is to compare the effect of non-invasive high-frequency oscillatory ventilation (NHFOV) and nasal continuous positive airway pressure (NCPAP) in preterm infants with respiratory distress syndrome (RDS) as a primary non-invasive ventilation support mode...

OBJECTIVE: Non-invasive high-frequency oscillatory ventilation (nHFOV) has recently been described as a novel mode of respiratory support for premature infants. This study was designed to determine whether nHFOV decreases CO2 partial pressure (pCO2 ) in premature infants more effectively than non-invasive continuous positive airway pressure (nCPAP). DESIGN: Non-blinded prospective randomised controlled cross-over study. SETTING: University Medical Center tertiary neonatal intensive care unit...

OBJECTIVE: Nasal high-frequency oscillatory ventilation (nHFOV) is a novel mode of non-invasive ventilation used in neonates. However, upper airway obstructions due to viscous secretions have been described as specific adverse effects. We hypothesized that high-frequency oscillations reduce air humidity in the oropharynx, resulting in upper airway desiccation. Therefore, we aimed to investigate the effects of nHFOV ventilatory settings on oropharyngeal gas conditions. METHODS: NHFOV or nasal continuous positive airway pressure (nCPAP) was applied, along with heated humidification, to a previously established neonatal bench model that simulates oropharyngeal gas conditions during spontaneous breathing through an open mouth...

OBJECTIVE: The aim of this study was to compare the effect of noninvasive high-frequency oscillatory ventilation (nHFOV) with nasal continuous positive airway pressure (nCPAP) in preterm infants with moderate-severe respiratory distress syndrome (RDS) after surfactant administration via INSURE (intubation, surfactant, extubation) method on the need for invasive mechanical ventilation (IMV). METHODS: A total of 81 infants with a gestational age (GA) of 28-34 weeks were eligible and were randomized to nCPAP (n = 42) or to nHFOV (n = 39)...

Objective: To evaluate the effectiveness and safety of the use of noninvasive high-frequency oscillation ventilation (nHFOV) in very low birth weight infants. Method: A total of 36 cases received nHFOV between January 2016 and October 2016 in Children's Hospital, Zhejiang University School of Medicine, including 24 males and 12 females, with the gestational age of (27.5±2.5) weeks and birth weight of(980±318)g. The data of the ventilator settings, side effects, and changes of the respiratory function before and after nHFOV were collected and analyzed retrospectively...

OBJECTIVE: Nasal high frequency oscillatory ventilation (nHFOV) is a promising mode of non-invasive neonatal respiratory support. To combine the effects of nasal continuous positive airway pressure (nCPAP) and high frequency oscillatory ventilation, an oscillatory pressure waveform is superposed to a nCPAP via a nasal or nasopharyngeal interface. nHFOV has been described to facilitate carbon dioxide (CO2 ) elimination compared to nCPAP. The influence of unintended leakage on CO2 elimination has not been investigated in nHFOV before...

Non-invasive high-frequency oscillatory ventilation (NHFOV) consists of the application of a bias flow generating a continuous distending positive pressure with superimposed oscillations, which have constant frequency and active expiratory phase. NHFOV matches together the advantages of high-frequency ventilation (no need for synchronisation, high efficacy in removing CO2 ) and nasal continuous positive airway pressure (CPAP) (non-invasive interface, increase in functional residual capacity allowing oxygenation to improve)...

After the High Frequency Oscillatory Ventilation (HFOV) has been applied in the invasive ventilator, the new technique of noninvasive High Frequency Oscillatory Ventilation (nHFOV) which does not require opening the patient's airway has attracted much attention from the field. This paper proposes the design of an experimental positive pressure-controlled nHFOV ventilator which utilizes a blower and a special valve and has three ventilation modes: spontaneous controlled ventilation combining HFOV, time-cycled ventilation combining HFOV (T-HFOV), and continuous positive airway pressure ventilation combining HFOV...

OBJECTIVE: Noninvasive high frequency oscillatory ventilation (NHFOV) has not been studied beyond neonatal age and with interfaces other than nasal prongs. We set up a preliminary study to investigate feasibility, oscillation transmission, and volume delivery of face mask-delivered NHFOV in a bench model mimicking a normal 1-year infant without any lung disease and then in vivo in a series of infants with same characteristics. DESIGN: A mannequin with upper airways was connected to an electronic active lung simulator ventilated through NHFOV with varying parameters...

BACKGROUND: We have previously shown that nasal pressure support ventilation (nPSV) can lead to an active inspiratory laryngeal narrowing in lambs. This, in turn, can limit lung ventilation and divert air into the digestive system, with potentially deleterious consequences. On the other hand, nasal high-frequency oscillatory ventilation (nHFOV) is particularly attractive in newborns, especially since, unlike nPSV, it does not require synchronization with the patient's inspiratory efforts...

UNLABELLED: Nasal high-frequency oscillation ventilation (nHFOV) is a non-invasive ventilation mode that applies an oscillatory pressure waveform to the airways using a nasal interface. nHFOV has been shown to facilitate carbon dioxide expiration, but little is known about its use in neonates. In a questionnaire-based survey, we assessed nHFOV use in neonatal intensive care units (NICUs) in Austria, Switzerland, Germany, the Netherlands, and Sweden. Questions included indications for nHFOV, equipment used, ventilator settings, and observed side effects...

BACKGROUND AND OBJECTIVES: Non-invasive high frequency oscillatory ventilation through nasal prongs (nHFOV) has been proposed to combine the advantages of oscillatory pressure waveform and non-invasive interface. We studied the effect of oscillation amplitude and inspiratory time on the pressure transmission and tidal volume delivery through different nasal prongs. METHODS: In vitro mechanical study on a previously described bench model of nHFOV. The model was built connecting SM3100A tubings to a neonatal lung model, via two differently sized binasal prongs...

OBJECTIVE: To investigate the feasibility of nasopharyngeal high-frequency oscillatory ventilation (nHFOV) immediately after extubation in difficult-to-wean preterm infants. STUDY DESIGN: This was an observational study of 20 mechanically ventilated neonates [median (range) birth weight 635 (382-1020)g, median gestational age 25.3 (23.7-27.6) weeks] at high risk for extubation failure. Nine infants had failed at least one previous extubation. Fourteen infants were given hydrocortisone...

BACKGROUND: Noninvasive high frequency oscillatory ventilation through nasal prongs (nHFOV) has been proposed as a new respiratory support in neonatology. We studied the effect of ventilation parameters and nasal prongs on nHFOV efficacy and mechanics. METHODS: Customized sealed circuits connecting a SM3100A oscillator to a neonatal lung model were developed to evaluate the effect of applying HFOV via two different sized nasal prongs on delivered tidal volume and pressure...
