Textbook Problem

A 73-year-old man with a long history of smoking demonstrates the following clinical data on a pulmonary function test(PFT):

Based on the information shown, the patient appears to have

An obstructive lung disorder

A restictive lung disorder

Both obstructive and restrictive lung disorders

Neither an obstructive nor restrictive lung disorder

Summary Introduction

Introduction:

Pulmonary function tests involve the evaluation of the respiratory system for the identification of the severity of the impairment of lungs. There are several tests which are used to distinguish between the different types of lung disorders.

Explanation

Justification for the correct answer:

Option (A) is, ‘obstructive lung disorder’. In obstructive lung disorder, RV (residual volume) and FRC (functional residual capacity) increase. VC (vital capacity) and ERV (expiratory reserve volume), FEVT (forced expiratory volume timed), FEF (forced expiratory flow), PEFR (peak expiratory flow rate), and MVV (maximum voluntary ventilation) decrease. Hence, option (A) is the correct answer.

Justification for the incorrect answers:

Option (B) is, ‘restrictive lung disorder’. It is false, as in restrictive lung disorder, VC, RV and FRC decrease...
