PULMONARY FUNCTION TESTING (PFT) EXAM 2025 QUESTIONS AND ANSWERS
tidal volume - (answer)Air moved during quiet respiration
inspiratory reserve volume - (answer)amount can inhale above tidal volume
expiratory reserve volume - (answer)amount can exhale after tidal volume
vital capacity - (answer)IRV + TV + ERV: Maximum amount of air that can be exhaled
forced vital capacity - (answer)move air out of lungs as hard as possible
exhale, biggest breath in that can take, and then breathe out as fast and as much as can
forced expiratory volume in 1 sec - (answer)first second of forced vital capacity maneuver
most normal people can get out most of the volume in 1 sec
FEV1 values - (answer)Determines Obstructive disease severity
FEF25-75 - (answer)mid 50% of expiratory flow "maneuver"; represents flow through small peripheral
airway issues
effective in identifying between smokers and non smokers because it *ids small airway issues*
these are sites of gas exchange so impairments here lead to more disability
maximum voluntary ventilation - (answer)breathe in and out as fast as can over about 10 sec period
then multiply by 6 to get minute value (DON'T make pt do for a full minute because will hyperventilate)
