Midland non-invasive ventilation score: a tool to predict non-invasive ventilation failure in people with acute hypercapnic respiratory failure

摘要

Use of non-invasive ventilation (NIV) in patients with hypercapnic respiratory failure has clear benefits over invasive ventilation. Existing risk prediction models are complex and difficult to apply in the acute setting. We developed the Midland NIV score comprising only five parameters for use to predict NIV failure (in-hospital death or intubation) at initiation. Individuals with Midland NIV score of = 12 (average 66% NIV failure rate). Prospective external validation is required.
