👉🏼This Brazilian multicenter study reports the largest cohort to date of patients treated with Helmet-CPAP, including 1,685 patients with COVID-19–related acute hypoxemic respiratory failure who used the nationally developed ELMO device (Ceará, Brazil).

🫁 Main findings

• 63% of patients, many with severe hypoxemia and ARDS, did not require intubation.

• Overall hospital mortality was 24%, occurring predominantly among patients who required invasive mechanical ventilation.

• Helmet-CPAP was implemented at large scale, including outside the ICU, in dedicated wards and resource-limited settings.

⭐ Original contributions

• Largest published global cohort of Helmet-CPAP to date.

• First large-scale clinical evidence using the ELMO helmet, a technology developed in a middle-income country.

• Real-world data supporting a scalable noninvasive respiratory support strategy during a public health crisis.

📊 Predictors of success and failure

Factors associated with success:

• Younger age and lower systemic severity

• Better baseline oxygenation

• Early physiological improvement in the first hours of therapy

Factors associated with failure:

• Systemic organ dysfunction

• Elevated inflammatory markers

• Interface intolerance

These findings reinforce that appropriate patient selection and early monitoring are critical to optimize outcomes.

 🌎 Practical implications

This study supports Helmet-CPAP as a feasible and scalable strategy for managing acute hypoxemic respiratory failure, particularly in healthcare systems under pressure. The data suggest that helmet-based support may:

• Expand respiratory support capacity beyond the ICU

• Reduce the need for invasive ventilation in selected patients

• Serve as a strategic option during future respiratory pandemics
