Function Equipment Qs & As
What piece of PFT equipment is used to measure Peak Expiratory Flowrates
(PEFR) at the bedside? Correct Answer-Peak flow meters
How does a patient perform a PEFR? Correct Answer-The patient exhales
forcefully through the device which incorporates a resistor and a moveable
indicator
What is the accuracy of a peak flow meter affected by? Correct Answer-
Patient effort
What two things other than patient effort can affect the accuracy of a peak flow
measurement? Correct Answer-1. Moisture
2. Debris
What should be instructed to the patient in order to find their personal best
peak flow? Correct Answer-The patient should be instructed to record their
peak from every day, morning and afternoon, for two to three weeks during a
period when their asthma is under control
