Show Hint
Spirometer measures lung capacity and airflow.
Updated On: Jun 20, 2026
- Clinical assessment of pulmonary functions
- Clinical assessment of heart function
- Clinical assessment of liver function
- Clinical assessment of brain function
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding spirometer.
A spirometer is an instrument used to measure lung volumes and capacities.
Step 2: Function in physiology.
It evaluates how much air a person can inhale and exhale.
Step 3: Clinical relevance.
It is widely used to diagnose respiratory disorders like asthma and COPD.
Step 4: Evaluating options.
Only pulmonary function assessment matches spirometer usage.
Step 5: Logical reasoning.
Heart, liver, and brain functions require different diagnostic tools.
Step 6: Final conclusion.
Thus, spirometer is used for pulmonary function assessment.
