All of the following are true about MIP except:

A patient’s FEV1 falls 14% from the prechallenge value after inhalation of the diluent (saline) before a methacholine challenge.  You should:

The minimum decrease in FEV1 that typically qualifies a methacholine challenge as positive is:

The respiratory pressures of MIPs and MEPs are measured under dynamic conditions (i.e., during airflow).

The following results are from a methocholine challenge: Step FEV1 Pre-challenge 3.10 Diluent 3.02 0.031 mg/ml 2.93 0.0625 mg/ml 2.81 0.125 mg/ml 2.79 0.25 mg/ml 2.48 0.5 mg/ml 2.30 These results are consistent with:

CO2 production (VCO2) increases linearly with work up to approximately the point that anaerobic metabolism begins.  At that point, the CO2 production

A respiratory therapist is responsible for cleaning a fiberoptic bronchoscope following a procedure.  Which of the following sterilization techniques is appropriate?

The main cardiovascular response to exercise is:

Generally, what percentage fall in FEV1 from pre-exercise levels defines an abnormal or positive response to exercise?

The respiratory exchange ratio measures the relationship of:
