Positive pressure ventilation (PPV) via a face mask is an important skill taught using manikins. There have been few attempts to assess the effectiveness of different face mask designs.
To determine whether leak at the face mask during simulated neonatal resuscitation differed between a new round mask design and the current most widely used model.
50 participants gave PPV to a modified manikin designed to measure leak at the face mask. Leak was calculated from the difference between the inspired and expired tidal volumes.
Mask leak varied widely with no significant difference between devices; mean (SD) percentage leak for the Laerdal round mask was 55% (31) and with the Fisher & Paykel mask it was 57% (25).
We compared a new neonatal face mask with an established design and found no difference in leak. On average the mask leak was >50% irrespective of operator experience or technique.
通过面罩进行正压通气（PPV）是使用人体模型教授的一项重要技能。很少有人尝试评估不同面罩设计的有效性。
确定在模拟新生儿复苏过程中，新型圆形面罩设计与当前使用最广泛的型号之间，面罩处的漏气情况是否存在差异。
50名参与者对一个经过改良的人体模型进行PPV，该模型旨在测量面罩处的漏气情况。漏气量通过吸气潮气量与呼气潮气量之间的差值计算得出。
面罩漏气情况差异很大，不同设备之间无显著差异；Laerdal圆形面罩的平均（标准差）漏气百分比为55%（31），Fisher & Paykel面罩为57%（25）。
我们将一种新型新生儿面罩与一种既定设计进行了比较，发现漏气情况没有差异。无论操作者的经验或技术如何，平均面罩漏气率均>50%。
