CPFT Practice Exam 2025 – Complete Test Prep Guide

When it comes to measurements in pulmonary function testing, accuracy and precision are critical characteristics of the equipment used.

Accuracy refers to how close a measurement is to the true value or the accepted standard. In the context of pulmonary function testing, accurate results ensure that healthcare providers can correctly assess a patient’s respiratory function and make informed decisions regarding diagnosis and treatment.

Precision, on the other hand, refers to the consistency of measurements. A precise measuring device will produce similar results under unchanged conditions. This consistency allows for reliable monitoring of a patient’s condition over time, ensuring that any changes observed are due to actual physiological changes, rather than variability in measurement.

These two characteristics work together to ensure high-quality, reliable data. Without them, the results of pulmonary function tests could lead to misinterpretation and inadequate patient care. The importance of these traits makes them the priority when selecting and utilizing measurement equipment in a clinical setting.
