Oxygenation Methods and Non-invasive Ventilation in Patients With Acute Respiratory Failure and a do Not Intubate Order

ICU care of patients considered "palliative" but without contraindications to admission to intensive care, for whom a do-not intubate order decision was made upon admission represents a particular target for non-invasive oxygenation techniques. The benefits of non invasive ventilation (NIV) in this population are debated especially in cancer patients. The more recently used nasal humidified high flux canula oxygenation (HFNC) therapy may have benefits over NIV in these patients. It is supposed to have better tolerance and could allow better compliance and thus higher efficiency. These potential benefits are major for such a population for which tolerance and symptomatic relief are priority goals
