Question 21

It is a disposable, plastic devise with two protruding prongs for insertion into the nostrils, connected to an oxygen source.
Used for low-medium concentrations of Oxygen (24-44%).

Answer 21

Nasal cannula (prongs):

Question 22

It delivers 35% to 60% oxygen.
A flow rate of 6 to 10 liters per minute.
It has vents on its sides which allow ro air to leak in at many places, thereby diluting the source oxygen.
>
Often it is used when an increased delivery of oxygen is needed for short periods (ie., less than 12 hours).

Answer 22

The simple Oxygen mask
