Randomized Controlled Trial Multicenter StudyUnder-The-Nose Versus Over-The-Nose Face Mask to Prevent Facial Pressure Sores During Face Mask-Delivered Noninvasive Ventilation for Acute Hypercapnic Respiratory Failure: A Randomized Controlled Trial.
To determine whether an under-the-nose face mask (FM) as the first-line interface strategy reduces the incidence of facial pressure sores with the same clinical improvement as the one obtained by standard over-the-nose face mask-noninvasive ventilation (FM-NIV) in patients with acute hypercapnic respiratory failure (AHRF). ⋯ In patients with AHRF, under-the-nose FM significantly reduced the incidence of facial pressure sores compared to the most commonly used first-line interface, the standard FM. However, with this new mask, excessive unintentional air leaks more often compelled the attending clinician to switch to another interface to pursue NIV.
