Acute Hypoxemic Respiratory Failure, COVID-19
Conditions
Keywords
helmet nonivasive ventilation
Brief summary
Study hypothesis: Non-invasive positive pressure ventilation delivered by helmet will reduce 28-day all-cause mortality in patients with suspected or confirmed severe COVID-19 pneumonia and acute hypoxemic respiratory failure
Detailed description
This will be a pragmatic parallel randomized control trial that will compare helmet nonivasive ventilation with standard of care to standard of care alone in 1:1 ratio. The trial will be implemented in multiple centers.
Interventions
Patients will be allocated to helmet non-invasive ventilation

Eligibility
Inclusion criteria
* Suspected or confirmed COVID-19 * Aged ≥14 years old at the participating ICU. ICUs that use other age cut-off for adult patients will adhere to their local standard (16 or 18 years) * Acute hypoxemic respiratory failure based on PaO2/FiO2 ratio \<200 despite supplemental oxygen with a partial or non-rebreathing mask at a flow rate \>10 L/min or above * Intact airway protective gag reflex * Able to follow instructions (e.g. squeeze hand on command, eye contact with care provider, stick out tongue on command, etc.)
Exclusion criteria
* Prior intubation during this hospital admission * Cardiopulmonary arrest * Glasgow coma scale \<12 * Tracheostomy * Upper airway obstruction * Active epistaxis * Requirement for more than one vasopressor to maintain mean arterial pressure \> 65 mm Hg * Pregnancy * Imminent intubation * Patients with do not intubate orders or equivalent * Enrolled in another trial for which co-enrolment is not approved including trials on mechanical ventilation * Patients already treated with helmet * Patients with chronic carbon dioxide retention (PaCO2 \>45) * Previous enrolment in this trial * The primary cause of respiratory failure is not heart failure as judged by the treating team

Primary
| Measure | Time frame | Description |
|---|---|---|
| 28-day all-cause mortality | 28 days from randomization | all cause mortality |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Intubation rate within 28 days | 28 days from randomization | endotracheal intubation |
| ICU mortality | 180 days from randomization | ICU death |
| Hospital mortality (censored at day 180) | 180 days from randomization | hospital death |
| Hospital length of stay | 180 days from randomization | length of stay in the hospital |
| ICU free days at day 28 | 28 days from randomization | days not in ICU |
| Invasive ventilation-free days at day 28 | 28 days from randomization | days without ventilator support |
| Renal replacement therapy-free days at day 28 | 28 days from randomization | days without renal replacement therapy received |
| Vasopressor-free days at day 28 | 28 days from randomization | days without vasopressor support |
| Safety outcome: skin pressure ulcers | 28 days from randomization | presence of pressure ulcers |
| Safety outcome: barotrauma | 28 days from randomization | incidence of barotrauma |
| Serious adverse events (including cardiovascular events and device complications) | 28 days from randomization | reporting of abovementioned adverse events |
| 180-day all-cause mortality | 180 days from randomization | all cause mortality |
| Follow-up study: 180-day 5-level EQ-5D version | 180 days from randomization | The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. |
