Résumé
Insufficient data are available about the noise produced by modern neonatal ventilators. We aimed to measure their noise under different ventilatory modes and parameters. This was a bench study measuring the noise produced by 9 neonatal ventilators set in conventional or high-frequency oscillatory ventilation (HFOV), nasal mask-delivered CPAP with variable- or continuous-flow configuration, or bi-level positive airway pressure (considered as noninvasive ventilation [NIV]). Conventional ventilation and HFOV were tested in 2 distinct settings with moderate or higher parameters. Sound measurements were performed inside and outside an incubator mimicking the clinical setting and using a high-end meter meeting the international ISO 226:2003 standard. Four ventilators remained below the internationally recommended safety threshold but only for measurements outside the incubator. Conventional ventilation (49.1 [3.4] dBA) and HFOV (56.3 [5.2] dBA) were the least and most noisy respiratory support technique, respectively. Noise was greater inside than outside the incubators ( Modern ventilators often produce relevant noise, independent of the respiratory support modality, with acceptable noise levels being measured only outside the incubator. Better results were achieved with Servo-u, VN500, and Fabian family devices.

BACKGROUND
BACKGROUND
Insufficient data are available about the noise produced by modern neonatal ventilators. We aimed to measure their noise under different ventilatory modes and parameters.
METHODS
METHODS
This was a bench study measuring the noise produced by 9 neonatal ventilators set in conventional or high-frequency oscillatory ventilation (HFOV), nasal mask-delivered CPAP with variable- or continuous-flow configuration, or bi-level positive airway pressure (considered as noninvasive ventilation [NIV]). Conventional ventilation and HFOV were tested in 2 distinct settings with moderate or higher parameters. Sound measurements were performed inside and outside an incubator mimicking the clinical setting and using a high-end meter meeting the international ISO 226:2003 standard.
RESULTS
RESULTS
Four ventilators remained below the internationally recommended safety threshold but only for measurements outside the incubator. Conventional ventilation (49.1 [3.4] dBA) and HFOV (56.3 [5.2] dBA) were the least and most noisy respiratory support technique, respectively. Noise was greater inside than outside the incubators (
CONCLUSIONS
CONCLUSIONS
Modern ventilators often produce relevant noise, independent of the respiratory support modality, with acceptable noise levels being measured only outside the incubator. Better results were achieved with Servo-u, VN500, and Fabian family devices.
