Method'flow rates'Warnings

Nasal Canula 1L/min=24% check frequently that both prongs are in patient's nares 2L/min=28%

                    3L/min=32%            
                    4L/min=36%            
                    5L/min=40%
                    6L/min=44%

Simple Mask Low Flow Monitor frequently for mask placement

                    6-10L/min= 35-60%      assess for claustrophobia
                    (6L/min= minimum flow) 

NOTE: Flow rates below 6L/min may be insufficient to clear exhaled CO₂ from the mask causing the patient to re-breathe it on their next breath, elevating PCO₂ levels in the blood.) Secure physician's order to use cannula during meals

Partial rebreather mask Low Flow Set flow rate so that mask remains two-thirds full during

                    6-15L/min=70-90%       inspiration

Nonrebreather mask Low flow Maintain flow rate so that bag collapses only partialy

                    6-15L/min=60-100%      during inspiration

                                           Check that valves and rubber flaps are open during
                                           expiration and closed during inhalation

Venturi mask High Flow carefuly monitor to verify fraction of inspired Oxygen (FiO2)

                    4-10L/min= 24%-55%
