After a baseline PFT a patient takes 2 puffs of albuterol and (post)testing is done immediately. The results do not improve much, what would you recommend? | wait 15-20 minutes and repeat the post bronchodilator test |
A patient has performed 2 flow-volume loops. As you compare the loops you notice the inspiratory flow curves were the same but the expiratory flow curve of the second loop was lower, based on this information you should; | have the patient repeat the test and instruct him to blow out as hard as possible throughout the test |
What % improvement during a pre and post bronchodilator study is considered significant? | 15% |
What is the purpose of 'pre and post bronchodilator' testing? | To determine reversible airway disease |
What are 3 indications for pre and post bronchodilator testing? | 1. cough of unknown orgin, 2. known asthmatic condition, 3. anytime airway hyperreactivity is suspected |
A patient just took 2 puffs of Vanceril, what should be done? | proceed with the pre-post bronchodilator study |
What is the minimum change in the post bronchodilator spirometry necessary to consider the reversibilty of Raw significant | 15% |
A methacholine challenge test determines: | airway reactivity |
