Correlation of clinical and breathing measures with failure of non-invasive respiratory support in acute respiratory failure
CORALINE - Correlation Between Physiological and Clinical Variables and Failure of Non-Invasive Respiratory Support in Patients With Acute Respiratory Failure
This project will try to see if routine clinical signs and breathing measurements can predict when high-flow oxygen or non-invasive ventilation won't prevent the need for a breathing tube in adults with acute respiratory failure.

What this trial studies
This is an observational study combining retrospective chart review with prospective physiological data collection in hospitalized adults with acute respiratory failure treated with high-flow nasal oxygen or non-invasive ventilation. Clinical variables and bedside respiratory measurements, including inspiratory effort monitoring, will be recorded at defined time points during routine care. The primary outcome is failure of non-invasive respiratory support, defined as need for orotracheal intubation; secondary outcomes include in-hospital and 90-day mortality, ICU and hospital length of stay, and durations of non-invasive and invasive support. Data will be collected at AOU Policlinico di Modena and analyzed to identify which variables are associated with non-invasive support failure.
Who should consider this trial
Good fit: Adults (age ≥18) hospitalized in the Respiratory Medicine Unit at AOU Policlinico di Modena with acute hypoxemic and/or hypercapnic respiratory failure (PaO2/FiO2 < 300) who are being treated with HFNO or NIV and can provide informed consent are ideal candidates.
Not a fit: Patients who need immediate invasive ventilation on arrival, have known neuromuscular disease, are pregnant, or receive care outside the enrolling center are unlikely to benefit from participation.
Why it matters
Potential benefit: If successful, the findings could help clinicians identify patients on HFNO or NIV who are likely to need intubation sooner, allowing earlier escalation of care and potentially improving outcomes.
How similar studies have performed: Previous observational research has identified clinical and physiologic predictors of non-invasive support failure, though the addition of nasal pressure (Pnose) inspiratory-effort monitoring in routine care is relatively novel.
