The PEFR in normal healthy men ages 20 to 30 years may exceed

A. 300 L/min

B. 400 L/min

C. 500 L/min

D. 600 L/min

Summary Introduction

Introduction:

The rate of flow of gas in and out of the lungs can be used to discern the integrity of the airways. This flow of gas can also be used to observe the severity of the impairment of the airway. The flow rate tests are collectively known as pulmonary mechanic measurements. These measurements are used along with volumes and capacities.

Explanation

Justification for the correct answer:

Option (d) is given as 600 L/min. This option is correct as the PEFR is the maximum rate of flow of air which can be achieved during forced vital capacity (FVC) maneuver. It is measured using a flow-sensing device known as peak flow meter. For men, PEFR many exceed 10 L/sec (liter per second) or 600 L/min. Hence, option (d) is correct.

Justification for the incorrect answers:

Option (a) is given as 300 L/min. This is false as the PEFR for a normal healthy man is 600 L/min and 300 L/min is just half of this value...
