I presume you mean: Something to keep the nostrils and nasal mucosa from drying out. The answer is simple Vaseline. Petroleum jelly, or aquaphor, any very greasy skin care lubricant should be helpful. Salves are fine so long as they are not made of ingredients to which the patient is allergic, and they should be unscented and free of menthol or other irritants. Adding a humidifier to the O2 tubing can help. Ask UR MD
