What does Screening Spirometry observe at the bedside - correct answers FEV1, FVC, IC, flow volume loop and others What is a good test for restrictive lung disease? - correct answers Slow vital capacity (SVC) True or false, SVC should be higher than FVC and results not repeated? - correct answers True. if FVC is greater than SVC, shows poor results and repeat What is Force Vial Capacity? - correct answers Max volume exhaled, after Max inhalation with least time What is produced during FVC, that is needed to determine the presence of Obstructive disease? - correct answers flow data what data is produced during FVC maneuver? - correct answers FEV FEF 200- FEF 27-
What is FEF 200-1200? - correct answers flow indicating the condition (obstructive component) of LARGE airways Maximum speed detected on exhalation is __________________________? - correct answers peak flow When is peak flow used? - correct answers suspected patient with airway constriction diseases such as asthma What data is best indicator of obstruction disease? - correct answers FEV1.0/FVC% Normal values for FEV1/FVC% - correct answers 85% Minimum acceptable value for FEV1/FVC%? - correct answers 70% What is Maximum Voluntary Ventilation (MVV) - correct answers Max amount of gas that the patient moves in and out of the lungs in 12 to 15 seconds Indication of flow loop round in appearance - correct answers Vocal cord dysfunction and paralysis
What is required to measure airway resistance (RAW) - correct answers body box Using body box, FRC is usually called? - correct answers Thoracic gas volume What is used to measure of how well gases (O2 and CO2) move across the alveolar capillary membrane (ACM). - correct answers DLco or Dco What is normal DLco - correct answers 25 ml CO/min/mmHg (STPD) what type of patients have a poor DLco? - correct answers restricitive diseases that affect the alveolar capillary membrane (ARDS) What disease is the only obstructive disease associated with poor DLco? - correct answers Emphysema; because it involves destruction of the alveoli Patient has the following PFT results? SVC 88% FVC 82% FEV1.0 sec 52%
FEF 25-75 55%
FEF 200-1200 78%
DLCO 62%
patient has what type of disease? - correct answers Emphysema Patient PF pre bronchodilator is 54% and post bronchodilator is 68%, what should be concluded from these values? - correct answers that condition is reversible because of 12% increase in flows observed What should RT instructed patient not to do prior to PRe and Post Bronchodilator studies? - correct answers reframe from using Bronchodialtors medications for 8 hours before test After patient completes a body box study, it was found that a Asthma patient has RAW of 1.4 cmH2O/L/SEC. - correct answers patient is normal What is normal value of RAW-- - correct answers 0.6 to 2.4 cmH2O/L/sec
What is the following disease a. Sarcoidosis b. Emphysema c. Pulmonary fibrosis d. Asthma - correct answers b. Emphysema Patient performed a Pre and Post Bronchdilator study and had a 10% change. What is the outcome? - correct answers bronchodilator not effective for reversible b/c didn't raise over 12% IF patient FEV1 raises more than __________ml, it is considered reversible when performing PRE/POST bronchodilator study? - correct answers 200ml How long should a patient reframe from using bronchodilators prior to Pre/Post Bronchodilator study? - correct answers 8 hours What are basic PFT interpretation for Obstructive impairment - correct answers FEV1/FVC%---->70% FEV1/FVC% not available, look at FEV1 > 80%
Slow Vital Capacity is look at for what disease process? - correct answers Restrictive, if SVC not available then look at FVC If VC is less than 80%, patient are considered? - correct answers restrictive IF patient is 80% or less for DLco, that are considered to have what condition? - correct answers diffusion impairment Acceptable range for DLCO? - correct answers 20-25 ml CO/min/mmHg IF patient predicted is 80% or greaters for most PFT results, they are considered? - correct answers normal PFT results between 60-79% - correct answers mild reduced 40-59% of predicted values for PFT - correct answers moderate change IF PFT is less than 40% of predicted values? - correct answers Severe
