Various oxygenization methods are used in the treatment of respiratory failure in acute heart failure. Occasionally, after patients are stabilized by these ventilation methods, some maintain a degree of dyspnea or hypoxemia which does not improve and is unrelated to deterioration in the functional class or the need to optimize pharmacological treatment. High-flow oxygen systems administered via nasal cannula that are connected to heated humidifiers (HFT) are a good alternative for oxygenation, given that they are easy to use and have few complications. We studied a series of 5 patients with acute heart failure due to acute pulmonary edema with stable dyspnea or hypoxemia following noninvasive ventilation. All the patients were successfully treated with HFT, showing clinical and gasometric improvement and no complications or technical failures. We report our experience and discuss different aspects related to this oxygenation system.
各种氧合方法用于治疗急性心力衰竭中的呼吸衰竭。偶尔，在这些通气方法使患者稳定后，一些患者仍存在一定程度的呼吸困难或低氧血症，且这种情况既与心功能恶化无关，也与需要优化药物治疗无关。通过与热湿交换器（HFT）连接的鼻塞给予高流量氧气系统是一种很好的氧合替代方法，因为它易于使用且并发症较少。我们研究了一组 5 例因急性肺水肿导致急性心力衰竭的患者，这些患者在接受无创通气后出现稳定的呼吸困难或低氧血症。所有患者均成功接受 HFT 治疗，表现出临床和气体分析改善，无并发症或技术失败。我们报告了我们的经验，并讨论了与这种氧合系统相关的不同方面。
