Bag-valve masks are simple, squeezable tools for manual ventilation of patients and are the most common manual method used in both emergencies and routine surgical procedures. The simplicity and minimal cost of BVMs have contributed to their widespread use and sales of approximately 13.1 million disposable resuscitators annually in the U.S. alone. Despite the regular use of BVMs, providers of any training level regularly deliver ineffective ventilation or uncontrolled, inadvertent, forced over-inflation. Studies show that, while using a standard BVM, 88.4% of trained users exceeding the recommended pressure and 73.8% exceeding the recommended volume range2 Improper ventilation for even short periods can lead to two major complications 1) Lung injury from over-stretching (called volutrauma); too much air and 2) Lung injury from over-pressurization (called barotrauma); too much pressure. These conditions can lead to life-threatening conditions as well as prolonged and expensive hospital stays with costs approaching $170,000 (CAD) per injury. When used in emergency situations, execution of proper BVM technique is required to provide optimal oxygenation during CPR. Devices to monitor the depth and rate of CPR compressions are widely available and are soon to be required in all training centers by the AHA. However, no technologies exist to provide similar feedback for manual ventilation. It is likely that real-time feedback can reduce or eliminate the rate of dangerous ventilation among caregivers of all levels and that BVM training with feedback can lead to improved skill retention. Thus, a novel technique and complementary device have been developed to provide real time feedback to trained and training personnel and ensure they meet guidelines from the American Heart Association (AHA) and European Resuscitation Council (ERC). This project is a comprehensive system development pathway composed of three aims that will refine our sensor system and initiate studies into the benefits of real-time feedback during BVM usage. This method utilizes a unique sensor system that can be coupled to a bag valve mask to measure the air pressure and volume delivered to a patient. Using these metrics for each squeeze of the bag, this device can alert users of both excessive pressure and volume in real time.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

袋阀式面罩是用于患者手动通气的简单、可挤压的工具，是紧急情况和常规外科手术中最常用的手动方法。BVM的简单性和最低成本促进了其广泛使用，仅在美国每年就销售约1310万个一次性复苏器。尽管经常使用BVM，但任何培训水平的提供者经常提供无效的通气或不受控制的、无意的、强制的过度充气。研究表明，在使用标准BVM时，88.4%的经过培训的用户超过推荐压力，73.8%超过推荐容量范围2，即使是短时间的不当通气也会导致两种主要并发症：1）过度拉伸导致的肺损伤（称为体积创伤）;空气过多; 2）过度加压导致的肺损伤（称为气压创伤）;压力过大。这些情况可能导致危及生命的情况以及延长和昂贵的住院时间，每次受伤的费用接近170，000美元（CAD）。在紧急情况下使用时，需要执行适当的BVM技术，以在CPR期间提供最佳氧合。监测心肺复苏术按压深度和速率的设备广泛可用，并且很快将被AHA要求在所有培训中心使用。 然而，不存在为手动通气提供类似反馈的技术。很可能实时反馈可以减少或消除各级护理人员中的危险通气率，并且带反馈的BVM培训可以提高技能保留率。因此，已经开发了一种新的技术和补充设备，以向受过训练的人员和培训人员提供真实的时间反馈，并确保他们符合美国心脏协会（AHA）和欧洲复苏理事会（ERC）的指南。该项目是一个全面的系统开发途径，包括三个目标，将完善我们的传感器系统，并开始研究BVM使用过程中实时反馈的好处。该方法利用独特的传感器系统，该传感器系统可以耦合到袋阀面罩以测量输送给患者的空气压力和体积。使用这些指标的每一个挤压袋，该设备可以警告用户的压力和体积都过大，在真实的time.This奖项反映了NSF的法定使命，并已被认为是值得的支持，通过评估使用基金会的智力价值和更广泛的影响审查标准。
