持续气道正压(CPAP)是新生儿重症监护病房常用的呼吸支持模式。对于早产儿，鼻腔CPAP(NCPAP)治疗通常通过柔软的、生物兼容的鼻罩进行，适合长期直接皮肤接触，并牢固地贴在脸上。在这一脆弱的人群中，有限大小的NCPAP面罩会导致不合适的相关并发症和不良后果。我们推测，定制的NCPAP口罩将以更小的皮肤压力和带子张力改善新生儿的适合性，提高疗效并减少与NCPAP治疗相关的并发症。在IRB批准和知情同意后，我们评估了几种开发3D面部模型的方法来测试定制的3D nCPAP面具。这些方法包括基于相机的摄影测量、激光扫描和结构光扫描，使用运行Bellus3D FaceApp for iPhone或Heges应用程序的Bellus3D Face Camera Pro和iPhone X。这些数据被用来提供准确的3D新生儿面部模型。利用CAD软件，NCPAP插入物被设计成放置在专有的NCPAP面罩和模特婴儿的面部之间。将所设计的三维nCPAP面罩贴合到模型脸上。随后，将nCPAP口罩连接到呼吸机上提供CPAP，并放置校准的压力传感器和共线张力传感器来测量皮肤压力和nCPAP面罩带张力。摄影测量和激光扫描不适合新生儿面部。然而，结构光扫描技术产生了准确的3D新生儿面部模型。使用3D打印模具和硅注射制造的个性化nCPAP面罩插件在某些情况下有效地降低了表面压力和面罩带压力，与没有插入件的CPAP面罩相比，降低了50%以上。我们发现，现成的结构光扫描设备，如iPhone X，是一种低成本、安全、快速和准确的工具，可以开发出准确的早产儿面部地形模型。结构光扫描开发的3D nCPAP插入物应用于市售CPAP面罩，当用于模型新生儿面部时，显著降低了临床相关CPAP压力下的皮肤压力和肩带张力。这一工作流程可能有助于为新生儿生产个性化的NCPAP面罩，减少因不合适而导致的并发症。
Continuous positive airway pressure (CPAP) is a common mode of respiratory support used in neonatal intensive care units. In preterm infants, nasal CPAP (nCPAP) therapy is often delivered via soft, biocompatible nasal mask suitable for long-term direct skin contact and held firmly against the face. Limited sizes of nCPAP mask contribute to mal-fitting related complications and adverse outcomes in this fragile population. We hypothesized that custom-fit nCPAP masks will improve the fit with less skin pressure and strap tension improving efficacy and reducing complications associated with nCPAP therapy in neonates. After IRB approval and informed consent, we evaluated several methods to develop 3D facial models to test custom 3D nCPAP masks. These methods included camera-based photogrammetry, laser scanning and structured light scanning using a Bellus3D Face Camera Pro and iPhone X running either Bellus3D FaceApp for iPhone, or Heges application. This data was used to provide accurate 3D neonatal facial models. Using CAD software nCPAP inserts were designed to be placed between proprietary nCPAP mask and the model infant’s face. The resulted 3D designed nCPAP mask was form fitted to the model face. Subsequently, nCPAP masks were connected to a ventilator to provide CPAP and calibrated pressure sensors and co-linear tension sensors were placed to measures skin pressure and nCPAP mask strap tension. Photogrammetry and laser scanning were not suited to the neonatal face. However, structured light scanning techniques produced accurate 3D neonatal facial models. Individualized nCPAP mask inserts manufactured using 3D printed molds and silicon injection were effective at decreasing surface pressure and mask strap pressure in some cases by more than 50% compared to CPAP masks without inserts. We found that readily available structured light scanning devices such as the iPhone X are a low cost, safe, rapid, and accurate tool to develop accurate models of preterm infant facial topography. Structured light scanning developed 3D nCPAP inserts applied to commercially available CPAP masks significantly reduced skin pressure and strap tension at clinically relevant CPAP pressures when utilized on model neonatal faces. This workflow maybe useful at producing individualized nCPAP masks for neonates reducing complications due to misfit.
