Nasal continuous positive airway pressure (nCPAP) has been shown to improve the outcome of infants with respiratory distress syndrome. However, noise generation could be of concern. Therefore, our study was designed to measure the noise levels of various CPAP drivers.
For infants admitted to our neonatal intensive care unit and paediatric critical care unit, we measured the noise level in the oral cavity, using a microphonic probe with a flexible capillary tube. Various CPAP drivers and interfaces have been tested.
27 measurements were made in eight infants. Mean noise level was 88.6 (SD 18.8) dB and was correlated with flow (p<0.01) but not with pressure. A noise level above 90 dB was detected in 67% of the measurements.
nCPAP drivers are valuable devices for neonatal care that may prevent primary mechanical ventilation or re-intubation, but generate a large amount of noise, often higher than occupational limits accepted for adult workers. Therefore, new devices must be designed to minimise this possible noxious exposure of premature infants to unacceptably high noise levels.
经鼻持续气道正压通气（nCPAP）已被证明可改善呼吸窘迫综合征婴儿的预后。然而，产生的噪音可能令人担忧。因此，我们的研究旨在测量各种CPAP设备的噪音水平。
对于入住我们新生儿重症监护病房和儿科重症监护病房的婴儿，我们使用带有柔性毛细管的微音探头测量口腔内的噪音水平。测试了各种CPAP设备及其接口。
对8名婴儿进行了27次测量。平均噪音水平为88.6（标准差18.8）分贝，与流量相关（p<0.01），但与压力无关。67%的测量中检测到噪音水平高于9分贝。
nCPAP设备是新生儿护理中的重要设备，可预防初次机械通气或再次插管，但会产生大量噪音，通常高于成年工人可接受的职业限值。因此，必须设计新设备，以尽量减少早产儿暴露于过高噪音水平的有害影响。
