High-Flow Nasal Cannula versus Noninvasive Positive Pressure Ventilation in Patients with Heart Failure after Extubation: An Observational Cohort Study

Figure 2

Outcomes following extubation within 72 hours. In the HFNC group, eight patients required immediate reintubation once treatment failure developed, and the other seven patients used NPPV as rescue therapy. Rescue NPPV successfully avoided reintubation in five patients, but it failed in two patients. In the NPPV group, six patients needed reintubation because of treatment failure. HFNC, high-flow nasal cannula; NPPV, noninvasive positive pressure ventilation.
