-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 liters/min, breathing slowly with shallow respirations. Johan has a normal ventilatory pattern using 2 L/min. Ted’s FiO2 is most likely:
A- higher than Johan’s
B- lower than Johan’s
C- tha same as Johan’s
Oxygen flow of greater than 5 L/min is essential to prevent the carbon dioxide accumulation in the mask.
Pin index safety system is use to connect high-pressure gas cylinders to the regulators. It is used as a safety system in flowmeter.
