<P> The non-rebreather mask is utilized for patients with physical trauma , chronic airway limitation , cluster headache , smoke inhalation , and carbon monoxide poisoning , or any other patients who require high - concentration oxygen , but do not require breathing assistance . Patients uncomfortable with having a mask on their face , such as those with claustrophobia , or patients with injuries to the mouth are more likely to benefit from a nasal cannula , or passive ( `` blow - by '' ) oxygen . Patients who are unable to breathe on their own would require invasive or noninvasive mechanical ventilation . </P>
