Nasal Septal Injury: What do I do if there is redness of the nasal septum from the prongs?
If there is redness or grazing it is due to inadvertent pressure. The cannula must be off of the nasal septum at all times. Use velcro below the cannula. Nasal erosion or necrosis will not occur if the cannual does not compress the septum. For an area that is red, just reposition the prongs off the septum and allow the area to recover.
