The hood, also called helmet, has been used for treating patients since the 1990’s, mainly in Europe. Use of the hood across the world increased during 2020 when the COVID-19 pandemic hit. There is years of research to support the clinical benefits of using a hood for CPAP or NIV

The latest research

Helmet noninvasive support for acute hypoxemic respiratory failure: rationale, mechanism of action and bedside application. Cesarano, M., Greico, D.L., Michi, T. et al. Ann. Intensive Care 12, 94 (2022).

  • This is a narrative review of 100 studies discussing the physiological rationale for using hoods to treat hypoxemic patients
  • Using a hood for NIV improved oxygenation and lowered inspiratory effort compared with HFNC. Also, compared with the HFNC, using the hood for NIV was associated with a lower rate of endotracheal intubation (30% vs 51%)
  • When compared with facemask NIV, using the hood for NIV showed significant reduction in patients needing endotracheal intubation (18% vs 61%) and improved mortality rates, shortened ICU stays and increased ventilator-free days
