Helmet NIV in Acute Respiratory Failure

Not Applicable

Active, not recruiting

• Conditions: Acute Respiratory Failure

• Registration Number: NCT05022173
• Lead Sponsor: Hamilton Health Sciences Corporation

Brief Summary

Non-invasive ventilation (NIV) is a form of respiratory support that has been shown to prevent invasive mechanical ventilation and reduce mortality. This study will investigate the feasibility of performing a larger study examining whether a new modality of NIV, the helmet, is superior to the current face mask in reducing mortality in patients with sudden respiratory failure.

ICU mortality	28 days	Number of patients who die in ICU
Adverse events	28 days	Any complications related to NIV use
ICU length of stay	Censored at 28 days	Number of days that each patient spends in ICU
Duration of non-invasive ventilation	Censored at 28 days	Number of days that patient receives non-invasive ventilation
Comfort	28 days	Patient comfort with non-invasive ventilation
Hospital length of stay	Censored at 60 days	Number of days that each patients spends in hospital
