Which of the following formulas will calculate the number of hours an E cylinder will provide oxygen to a patient?
tank pressure (psi) x 0.3/ flow rate (LPM)
flow rate (LPM) x 0.3 / tank pressure (psi)
[tank pressure (PSI) x 0.3 / flowrate (LPM)] / 60
[flowrate (LPM) x 0.3 / tank pressure (PSI)] / 60
What tank factor is used to calculate how long an H cylinder will last when the pressure (PSI) and flowrate (LPM) are given?
How long will a full E cylinder last if run until empty with a flowrate of 10 LPM?
An H cylinder of oxygen has 1200 psi remaining in the tank. How long will it take to decrease to 200 psi if the flow is 5 LPM?
A patient will be away from their room for two hours while undergoing a special procedure in the radiology department. They will be using a full E cylinder. What is the maximum flow that the therapist could use without running out of oxygen?
Which of the following formulas will determine the total flow being delivered to a patient with a 28% venturi mask running at 6 LPM?
total flow = 6 x 2
total flow = 6 x 4
total flow = 6 x 5
total flow = 6 x 11
Which of the following is the air -to- oxygen ratio for a device delivering 60% oxygen?
