Answer to Question 1

ANS: A
A limit variable is one that can reach and maintain a preset level before inspiration ends but does not terminate inspiration.

Answer to Question 2

ANS: B
The ventilator measures the flow coming out of the main flow control valve and also the flow through the exhalation valve. Between breaths, these two flows are equal (assuming there are no leaks in the patient circuit). When the patient makes an inspiratory effort, the flow through the exhalation valve falls below the flow from the output valve. The difference between these two flows is the flow trigger variable.
