Oxygen Therapy: Devices, Flow Rates, and Safety
Oxygen is a drug, dosed by device and flow rate and titrated to a target. Choosing the right delivery device for the patient need is a core clinical skill, and so is knowing the safety risks.
QUICK ANSWER
Oxygen delivery devices range from a nasal cannula at 1 to 6 liters per minute, to a simple mask at 5 to 10, to a non-rebreather mask at 10 to 15 liters per minute for high concentrations. The device is chosen for the patient oxygen need and titrated to a target saturation. Oxygen supports combustion, so fire safety and proper flow settings are essential.
Matching Device to Need
- Nasal cannula: 1 to 6 L/min, low-flow, comfortable for stable patients.
- Simple face mask: 5 to 10 L/min, moderate concentrations.
- Non-rebreather mask: 10 to 15 L/min, high concentration for emergencies.
- Venturi mask: precise fixed concentrations, useful in COPD.
Titrate and Stay Safe
Oxygen is titrated to a target saturation, not simply run wide open, and some patients need careful control to avoid harm. Oxygen also accelerates fire, so no open flames, and connections and flow rates are checked before and during therapy.
A drug with a dose
Oxygen gets treated casually because it is invisible and everywhere. It is a drug with a target range, delivery device, and real safety risks.
Oxygen therapy pairs with vital signs monitoring and airway skills like suctioning.
WE BUILD THIS IN VR — THE PRIME VR
We build oxygen therapy into VR, so learners select the right device, set flow rates, and titrate to a target saturation while the system models the patient response and fire-safety hazards. It makes device selection and titration a practiced decision, not a guess.

What is the flow rate for a nasal cannula? +
A nasal cannula typically runs at 1 to 6 liters per minute, delivering low-flow supplemental oxygen. Higher needs require a mask device.
When is a non-rebreather mask used? +
A non-rebreather mask at 10 to 15 liters per minute delivers a high oxygen concentration and is used in emergencies or for severely hypoxic patients who need maximum oxygen short of positive pressure.
Why is oxygen a fire hazard? +
Oxygen supports and accelerates combustion, so open flames, smoking, and sparks are kept away from oxygen in use. Higher concentrations make any fire burn faster and hotter.
