WebOxygen delivery can be increased by use of oxygen reservoir device. Simple mask: delivers FiO2 35-55% at flows 5-12 L/min. Flows <5 L/min should not be used to prevent rebreathing of CO2. Face tent: FiO2 variable up to 50%; more comfortable than facemask. Venturi mask: 1-4 L/min, FiO2 preset at 24, 28, 31, 35, 40, and 50%. WebThe calculation of nasal cannula FiO2 is rather easy. For the most part, just add 4 for each liter of O2. We would obviously do this above room air (21%). The only exception to this rule is the first liter (you add 3) – consider this a favor done to get you onto numbers divisible by 4. So, this is how it goes: Room Air = 21%

Now if you give a patient a nasal cannula at one liter per minute, they’re going to get about 24 percent oxygen. Give them the two liters and they’re going to get about 28 percent. WebJan 9, 2024 · There is a general rule for determining FiO2 at a specific flow rate via the nasal cannula. It is known as the “rule of fours”, “which states that the FiO2 will increase 4% for every Liter/Min above 1.” 4 Here is an estimate of FiO2 delivery on a nasal cannula: 1L= 24%. 2L= 28%. 3L= 32%. 4L= 36%. 5L= 40%. 6L= 44% scar\\u0027s ws
