Dataset: Factors Associated with Immediate and Early Non-Invasive Ventilation Failure in Patients with Hypercapnic Respiratory Failure in the Emergency Department

This dataset contains clinical, demographic, vital sign, and laboratory records of 118 adult patients presenting to the emergency department with acute hypercapnic chronic obstructive pulmonary disease (COPD) exacerbations who underwent non-invasive ventilation (NIV). The data includes variables related to baseline and post-NIV arterial blood gases, mask fit assessments, ventilatory settings, and clinical outcomes (NIV success vs. failure) used for multivariable logistic regression and ROC analyses.
