At what rate does the Wright spirometer measure peak flow?
  1. 2pm
  2. 1pm
  3. 3pm
  4. 4pm
Explanation
Answer - B - The Wright spirometer measures peak flow at 1pm. 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.
