Lesson No. 12: CALCULATION OF TOTAL FLOW (VENTURI MASK)

[@ChrisHolbrook-yz6bp]

RRT here for 30 years. Aside from school, I’ve never used tis.

[@stevesarres7161]

When you add the 10 and 1 it = 11 times 4 is 44 then add 4 is 48. Can you explain. This is confusing me.

Thank you so much!!

[@izuwaqueenchiagozie6657]

Thanks for your help so far Please why do you use 21% for the first question and 20% for the second question

[@AtYourSIRvice]

Hi sorry for the super late response. I got too busy with work. To answer your question, use 21% if the fio2 is 30% and below. Use 20% if the fio2 is above 30%.

[@nguyenkhacman64]

What do the numbers 21% and 20% mean? Can you prove this formula?

[@AtYourSIRvice]

20-21% is the percentage of O2 in the environmental air.
