At what rate does the Wright respirometer measure peak flow?

2 LPM
1 LPM
3 LPM
4 LPM

Explanation

Answer: B - The Wright spirometer measures peak flow at 1 LPM. It is useful in determining the degree of lower-airway resistance and measuring the efficacy of treatments. For example, if you treat a patient with Albuterol treatments after measuring that the patient can blow 50% of a normal rate and then after treatment blow 80% of a normal rate, you can assume the treatments are working.
