Question

Quizplus · Accepted Answer

When a ventilator controls flow, it uses flow as a limit variable. This means that the ventilator will adjust the pressure in order to maintain a set flow rate, but will not exceed that flow rate. The other variables listed (pressure, time, and volume) can also be controlled by a ventilator, but in each case, a different variable is used as the limit. For example, when a ventilator controls pressure, it uses pressure as the limit variable and adjusts the flow rate to maintain that pressure.
