The desired FiO2= 40%, total flow= 12 L/min
Oxygen flow-meter setting= ___________L/min and Air flow-meter setting= ______________L/min
The desired FiO2= 40%, total flow= 12 L/min
Air contains 20% of oxygen.
To achieve 40% Fio2(Fraction of inspired oxygen) we need to flow 80% of air(which contains 20% oxygen) and 20% of pure oxygen.
The total flow is 12 litter
So, 80% of 12 litter is 9.6 litter and 20 % is 2.4 litter
Answer -
Oxygen flow-meter setting= 2.4 L/min
Air flow-meter setting= 9.6 L/min
The desired FiO2= 40%, total flow= 12 L/min Oxygen flow-meter setting= ___________L/min and Air flow-meter setting=...
An oxygen flowrate of 12 L/min is used on a 60% Oxygen: air entrainment mask. What is the O2: air entrainment ratio and total flow? ___________
Calculate the air: O2 ratio of 30% O2: air entrainment device ___________ An oxygen flowrate of 12 L/min is used on a 60% Oxygen: air entrainment mask. What is the O2: air entrainment ratio and total flow? ___________ If the patient’s blanket is covering the port on the air entrainment device, what is the FiO2 that is being delivered? _______%
-the main reason the oxygen flow to a simple mask should be greater than 5 L/min is to: A- produce a Venturi effect. B- provide an adequate FIO2. C- prevent CO2 accumulation in the mask. D- prevent airway drying -Which of the following safety systems relates to the threaded connector at the outlet of a flowmeter? A- quick connect outlet B- pin index system C- American standard system D- Diameter index system -Ted is using a nasal cannula at 2...

If the air in a 12-inch diameter duct with an air flow of 1,500 ft3/min and a velocity of 14 ft/min flows into a 6-inch diameter duct, what are the new flow rate and velocity? What velocity of air would be required to draw toxic vapors into a duct 24 inches away from a 12 inch round duct with an air flow rate of 1,500 ft3/min? Compare the flow rates into a hood that needs to capture a contaminant at...
Air Force servicemen and servicewomen were tested for maximal oxygen use in a 12 min distance run versus a 1.5 mile run. The participant runs on a level terrain for the prescribed distance. The technicians records the participant’s time to the closet second, the heart rate for 15 s immediately after the participant crosses the finish line and then estimate the VO2 max consumption using a Wilmore and Bergfeld fitness table. Below is listed the data for both the 12...

4. You are asked to assess a recently extubated patient. Following extubation, she was placed on a facemask with large-volume air-entrainment nebulizer at 40 % dilution and an O2 flow of 14 L/min. The Spo2 was 88% just prior to your arrival. The physician increased the FIO2 setting to 60 %, and the Spoz is now 84%. When you increase the nebulizer dilution setting 80%, the Spo2 decreases to 82%. How can you explain this clinical response and what would...
