Understanding Oxygen LPM Flow Rates and FiO2

Hospital-grade oxygen found in a medical facility can reach >99% FiO2. From these ranges, most oxygen concentrators can deliver >90% FiO2. However, that percentage drops substantially towards 21% FiO2 based on the flow rate you are usingin addition to a number of other factors.Treatment of Hypoxemia with an Oxygen Enricher - CHESTNote that only one specific flow rate produces the oxygen concentration of the mask being used, ie, 2 to 4 L/min for a 24 percent mask, 4 L/min for a 28 percent mask, 5 L/min for a 31 percent mask, 4 L/min for a 35 percent mask, and 4 L/min for a 40 percent mask.

Types: BLUE = 2-4L/min = 24% O 2 WHITE = 4-6L/min = 28% O 2Oxygen MasksThe venture mask, on the other hand, is an oxygen mask that uses a mechanical venturi effect in order to increase the flow rate of oxygen into the mask. Usually, this is used online in a clinical setting and is not advisable to be used in the field since it only delivers supplemental oxygen which is only about 24 to 28 percent.Obama proposes $94 billion energy tax hike in new "New legislation signed Wednesday provides manufacturers of N95 face masks protection against lawsuits when selling certain masks to health-care workers, Pence said.
