How can you estimate the patient's minimum effort when perfroming the MVV test? | FEV-1 x 35 |
Briefly describe the 'MVV' and list it's typical value | 1. Have patient breath deep/fast for 12 seconds (x5) 2. Typical value 170 l/min |
Briefly describe the 'FEF 25-75' and list it's typical value | 1. The flow rate during the middle 50% of exhalation. 2. typical value = 4-5 L |
Briefly describe the 'peak expiratory flowrate' and list it's typical value | 1. Maximum flow generated during expiration. 2. 300 l/min |
Briefly describe the 'FEF 200-1200' and list it's typical value | 1.The flowrate during the liter after the first 200 ml have been discarded. 2. typical value 6 l/min |
After performing a PFT on a 48 year old, the MVV is 55% of predicted and the FEV-1 is 76% of predicted; your intrepretation is | the patient's effort should be questioned |
Which test would you use to measure small airway function? | FEF(25-75) |
When performing an MVV test, the position of the spirometer bell on the Collins water-seal spirometer should be; | in the mid-position |
Why is it important to have pulmonary function values that are reproducible? | The only way that values are reproducible is from maximum effort |
