What is the primary purpose of a spirometer?

The primary purpose of a spirometer is to assess lung volumes and airflow. This device measures how much air a person can inhale and exhale, as well as the rate at which air is breathed in and out. These measurements are critical in evaluating respiratory function and diagnosing conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other pulmonary disorders.

Spirometry tests help healthcare providers determine whether the lungs are working effectively and can provide insight into how various conditions might be affecting breathing. This information can assist in tailoring treatment plans, tracking disease progression, and assessing the efficacy of interventions.

In contrast, measuring heart rate, checking blood oxygen levels, and monitoring body temperature involve different physiological parameters that are outside the scope of what a spirometer is designed to measure. Each of these aspects of health is assessed using separate devices and methods specific to those functions. Therefore, the spirometer's focus remains squarely on evaluating lung capacity and airflow levels, making it an essential tool in respiratory health assessments.
