Treatment of Chronic Respiratory Failure in Immunosuppressed Patients with Early Acute Respiratory Failure
Managing chronic respiratory failure becomes distinctly more complex when early acute respiratory failure develops in an immunosuppressed or post-operative patient. The choice of respiratory support in this setting is guided by specific evidence-based recommendations that differ from the general acute-on-chronic population.
Clinical Scenario
This protocol applies when chronic respiratory failure is complicated by early acute respiratory failure in a patient with immunosuppression (immunocompromised state) — including those in a post-operative setting. These features together define which respiratory support strategy international guidelines endorse for this population.
Approach
Current international guidelines support a noninvasive positive pressure ventilatory strategy for this scenario. The complete protocol — covering specific mode selection, patient selection criteria, monitoring, and escalation thresholds — is available in the full structured regimen.

The European Respiratory Society (ERS)/ATS guidelines recommend bilevel positive airway pressure (bilevel-PAP) for patients with acute exacerbation of COPD accompanied by acute hypercarbia, CPAP for cardiogenic pulmonary edema, and NPPV for post-operative setting and early ARF in immunosuppressed patients.
