Human lungs are 2 liters in volume by average. So... Average breath rate is 12 breaths per minute. In one minute the patient would take in 24 liters of air. You are supplying 2 liters of pure oxygen + 4.8 liters from air (20% of the 24 liters (Percent oxygen in dry air)) = 6.8 liters of Oxygen per minute. 6.8 liters oxygen / 24 liters intake = 28.3% Oxygen or you can look at the table given by the books at http://www.fpnotebook.com/ER/Procedure/LwFlwOxygn.htm Nasal Cannula, Flow 0 liters per minute: 21% (Room Air), Flow 2 liters per minute: 29% But I like the mathematical method. That's just me!

How many litres of oxygen is 28 % using a face mask?
To open the valve on an oxygen cylinder, you turn the valve.
it regulate the oxygen pressure
One with less than 500 litres!
2 hours and 30 minutes at 4.5 liters 2 hours and 15 minutes at 5 liters
The normal amount of oxygen a person takes in is about 7 to 8 liters. This is for every minute.
Convert 40% oxygen to liters
Take example that we r providing 2L/min of oxygen to a ptHuman lungs are 2 liters in volume by average. So...Average breath rate is 12 breaths per minute.In one minute the patient would take in 24 liters of air. You are supplying 2 liters of pure oxygen + 4.8 liters from air (20% of the 24 liters (Percent oxygen in dry air)) = 6.8 liters of Oxygen per minute.6.8 liters oxygen / 24 liters intake = 28.3% Oxygen
Convert oxygen litter/minute to percnt

An ML6 oxygen cylinder, when "charged" to normal pressures, holds 170 liters of oxygen. How long that will last depends on a number of factors. If the flow is set to 2 liters per minute continuous then it will last less than 1 and 1/2 hours. If an oxygen conserving device is used (they give the gas in pluses when breaths are taken) it can last over 4 hours.
An "E cylinder" is a particular size of oxygen cylinder. 29" tall just under 5" diameter with a capacity of 680 liters of oxygen.
