Understanding Oxygen LPM Flow Rates and FiO2 Percentages

Oxygen Flow Rates and Percentag The percentage of oxygen you are receiving from a given flow rate is not a precise science, but there are some guidelines you can rely on for a relatively accurate estimate Comparing the fraction of inspired oxygen (FiO2) in the air to a portable oxygen device is expressed as a percentage .

Depending on a patient's inspiratory effort (tidal volume, 'speed' of inspiration and respiratory rate) the PIFR can often exceed the flow rate at which oxygen or an oxygen/air mixture is supplied by the device, meaning that at the time of PIFR more or less entrainment of room air occurs, altering the resulting FiO2 in an unpredictable fashion
