The introduction of innovative mechanical ventilation technology requires a careful assessment of the cost-benefit relationship of the new technology. Justification for purchase can be sometimes be made on the basis of improved patient safety and physiologic response. Improved patient outcome is much more difficult to demonstrate. It is clear in today's health-care environment that outcome-based research is needed before new technology is introduced to the marketplace, if that new technology is to become part of the average community-hospital complement of mechanical ventilators.
引入创新的机械通气技术需要仔细评估新技术的成本效益关系。有时可以基于提高患者安全性和生理反应来证明购买的合理性。然而，要证明能改善患者预后则困难得多。在当今的医疗环境中很明显，如果新技术要成为普通社区医院机械通气设备的一部分，那么在将其推向市场之前需要进行基于结果的研究。
