Carbon dioxide rebreathing can occur if the oxygen flow to a simple or nonrebreathing mask is not sufficient to wash out the patient's exhaled gases.The flow of oxygen to a reservoir mask determines the FɪO₂,as do the patient's breathing pattern and the presence or absence of a reservoir bag.Those masks with a reservoir bag will have a higher FɪO₂ than those without a reservoir bag.
