Helmet continuous positive airway pressure is a simple, noninvasive respiratory support strategy to treat several forms of acute respiratory failure, such as cardiogenic pulmonary edema and pneumonia. Recently, it has been largely used worldwide during the COVID-19 pandemic. Given the increased use of helmet continuous positive airway pressure in the emergency department, we aimed to provide an updated practical guide for nurses and clinicians based on the latest available evidence. We focus our attention on how to set the respiratory circuit. Moreover, we discuss the interactions between flow generators, filters, and positive end-expiratory pressure valves and the consequences regarding the delivered gas flow, fraction of inspired oxygen, positive end-expiratory pressure, and noise level.
头盔持续正压通气是一种简单、无创的呼吸支持策略，可用于治疗多种类型的急性呼吸衰竭，如心源性肺水肿和肺炎。最近，在 COVID-19 大流行期间，头盔持续正压通气在全球范围内得到了广泛应用。鉴于在急诊科中头盔持续正压通气的使用增加，我们旨在根据最新可用证据为护士和临床医生提供更新的实用指南。我们关注如何设置呼吸回路。此外，我们还讨论了气流发生器、过滤器和呼气末正压阀之间的相互作用，以及它们对输送气体流量、吸入氧分数、呼气末正压和噪声水平的影响。
