Oxygen Flow Rate and Fraction of Inspired Oxygen (FiO2)
Nov 6, 2025 · The fraction of inspired oxygen (FiO2) provided by an oxygen concentrator varies depending on the device’s settings and flow rates. In general, these devices can deliver FiO2 levels …
Fraction of Inspired Oxygen (FiO2) for a nasal canula and a Venturi mask are given in the tables below. For other oxygen delivery systems, such as masks, tents, there is more oxygen that "blows by" or is …
Understanding Oxygen LPM Flow Rates and FiO2 Percentages
Aug 1, 2023 · How much FiO2 you receive from your oxygen concentrator depends on your flow rate. The flow rate is how many liters of oxygen, per minute, your device delivers. For example, patients …

Actual FiO2 depends on minute ventilation (i.e., effective FiO2 drops as respiratory rate increases). Oxygen delivery can be increased by use of oxygen reservoir device.
PaO2/FiO2 < 400 is one SOFA point. PaO2/FiO2 < 300 is two SOFA points and will support Severe Sepsis. PaO2/FiO2 < 300 also supports the hypoxia for the diagnosis of Acute Hypoxic Respiratory …
Rule of Thumb (already implicit in the tables): For most STOP-ROP infants, if flow (LPM) exceeds body weight (KG), then effective FIO2 equals nasal cannula oxygen concentration.
