A patient with newly diagnosed asthma is asking why peak flow measurements are being ordered. What is the best response by the nurse?
a. They measure the minimum force used to breathe in during the breathing process.
b. They measure the maximum flow that occurs when one quick, forced expiration is taken.
c. They measure the amount of circulating oxygen in the alveoli during breathing.
d. They indicate the stability of your overall health.
B
The peak expiratory flow measurements are objective indicators of the patient's current status and the effectiveness of the treatment. Decreased peak expiratory flow rate (PEFR) may indicate the need for further interventions such as increased doses of bronchodilators or antiinflammatory medications. The measurements focus on expiration, not inspiration, and do not reflect the amount of circulating oxygen in the alveoli. The peak expiratory flow measurements reflect only the respiratory system, not the overall health.
