Nasopharyngeal CPAP is a simple and useful technique for increasing FRC and stimulating respiration in small premature infants. However, as it is essentially a non-rebreathing technique, the gases used should be warmed and saturated to the level normally found in the pharynx with no artificial airway present (31 degrees to 33 degrees C, 90 per cent plus relative humidity). If this is not done, crusting, mucous plugging, atelectasis, hypoxia, and infection will occur rapidly. Excess humidity should also be avoided.
鼻持续气道正压通气是一种用于增加小早产儿功能残气量和刺激呼吸的简单且有用的技术。然而，由于它本质上是一种无重复呼吸技术，所使用的气体应加热并饱和至无人工气道时咽部通常的水平（31摄氏度至33摄氏度，相对湿度90%以上）。如果不这样做，将会迅速出现结痂、黏液堵塞、肺不张、缺氧和感染。还应避免过度加湿。
