Question 13

Question
FVC Measurements: Peak Expiratory Flowrate (PEFR) Maximum [blank_start]flowrate[blank_end] achieved during FVC 10 L/s Nonspecific in significance because it is very dependent on [blank_start]patient[blank_end] effort Measured in L/s ATPS corrected to BTPS Forced Expiratory Flow 200-1200 Average flowrate that occurs during FVC after the first [blank_start]200[blank_end]mL has been expired Typical: 6 L/s Significance: Measures airflow in [blank_start]big[blank_end] airways. Decreased with mechanical airway problems and [blank_start]obstructive[blank_end] disease, can be decreased d/t poor effort Forced Expiratory Flow 25%-75% Average flowrate during the [blank_start]middle[blank_end] half of FVC Typical: 4-5 L/s ATPS corrected to BTPS Significance: Measures flow in the [blank_start]small[blank_end] airways, is [blank_start]decreased[blank_end] in obstructive disease. Most sensitive to detect [blank_start]small[blank_end] airway disease. Can appear erroneously [blank_start]decreased[blank_end] if FVC and FEV1 are greatly increased in post bronchodilator studies. Forced Expiratory Volume/Time (FEVtime) Volume Expired of time interval Common: FEV.5, FEV1, FEV2, FEV3, FEV6 ATPS corrected to BTPS Significance: Decreased flows indicate obstructive disease, FEV1 used to assess improvement in post BD studies, allow 10-15 minutes in between pre/post tests. FEVT / FVC% Forced expiratory volume for time interval expressed as a percentage of total FVC Minimum acceptable values: FEV.5/FVC = [blank_start]60[blank_end]% FEV1/FVC = [blank_start]70[blank_end]% FEV2/FVC = [blank_start]94[blank_end]% FEV3/FVC = [blank_start]97[blank_end]% FEV6/FVC = [blank_start]99[blank_end]% Significance: [blank_start]decreased[blank_end] with obstructive disease, [blank_start]normal[blank_end] with restrictive.

Question 14

Question
FVC to Generate Flow-Volume Loop A forced expiratory maneuver followed by forced inspiratory maneuver Recorder plots flow ([blank_start]vertical[blank_end]) and volume ([blank_start]horizontal[blank_end]) for inspiration and expiration Expiration is [blank_start]above[blank_end] baseline, inspiration [blank_start]below[blank_end] baseline Important to coach max effort without [blank_start]coughing[blank_end] PEF is measured with pt at [blank_start]TLC[blank_end] PIF is measured with pt at [blank_start]RV[blank_end] Forced Expiratory Flow at 25%, 50%, and 75% of VC % is amount of [blank_start]FVC[blank_end] that has been exhaled Decreases in FEF50% and FEF75% indicate [blank_start]obstructive[blank_end] disease These values can be more sensitive in detecting small airway obstruction than FEV1. Forced Inspiratory Flow at 25%, 50% and 75% of Inspiratory Vital Capacity Measured on inspiratory side of loop useful when compared to expiratory Values for determining a site of large [blank_start]obstruction[blank_end] - particularly the [blank_start]50[blank_end]% value Maximum Forced Expiratory Flow (FEFmax) Highest flow achieved on expiratory curve Analagous to [blank_start]PEF[blank_end] FEFmax used to determine [blank_start]effort[blank_end]
