Room air is 21% oxygen.

For every liter of oxygen delivered by nasal cannula add 4% for example:

1L= 24%

2L=28%

3L=32% and so on.

Yes, its right but the formula of Lpm to FiO2 is:

lpm*4+20 = FiO2

Example:

1L*4+20 = 24%

2L*4+20 = 28%

3L*4+20 = 32% and so on.

To convert FiO2 from liters to a percentage:

  1. Determine the liters of oxygen being administered.
  2. Divide the liters of oxygen by 5 to get the approximate FiO2 percentage.
  3. For example, if 2 liters of oxygen is being administered, the FiO2 can be estimated at around 40% (2/5 = 0.4 or 40%).

Keep in mind that this is an approximation and actual FiO2 may vary depending on the oxygen delivery system used.
