Background: I have 4 set of results from different patients who have performed a spirometry test with reversibility. This test is used to determine if a patient improves their lung function after being given Ventolin which Is a medication usually prescribed to help Asthma patients. If a patient improves by 12% in either FEV1 or EVC it Is deemed a significant response. Questions I am given: 1. Please can you find the percent predicted change for both FEV1 and FVC between the Pre (Best) to Post value. 2. State if the pattent has a significant response to Ventolin.
