Claim 12:
13. A method comprising:
increasing, with a pump of a ventilator that is fluidly coupled to an outlet line of the ventilator, pressure in the outlet line of the ventilator during periodic inspiration pulses of an inspiration cycle of the ventilator;
during the periodic inspiration pulses of the inspiration cycle of the ventilator, actuating, with the pump of the ventilator, [[the]] flow of gas into a sample collection system; and
between the periodic inspiration pulses of the inspiration cycle of the ventilator, facilitating, with an outlet valve of the ventilator, the flow of gas out of the sample collection system, wherein:
the sample collection system is fluidly coupled to a valve system,
the valve system is fluidly coupled to the outlet line of the ventilator,
the sample collection system comprises a sample extraction device having a cavity containing one or more sorbents, and
the valve system comprises a first one-way valve that allows flow of gas into the sample collection system and a second one-way valve that allows flow of gas out of the sample collection system.
