HELMET CONTINUOUS POSITIVE AIRWAY PRESSURE IN THE EMERGENCY DEPARTMENT: A PRACTICAL GUIDE

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.

Automated summary

This study aims to provide a practical guide based on the latest evidence for nurses and clinicians on how to set the respiratory circuit and understand the interactions between flow generators, filters, and positive end-expiratory pressure valves in helmet continuous positive airway pressure. It also discusses the consequences regarding delivered gas flow, fraction of inspired oxygen, positive end-expiratory pressure, and noise level.
