Certified Respiratory Therapist Practice Exam 2025 – Complete Test Prep Guide

Electrochemical oxygen analyzers are designed to measure the concentration of oxygen in a gas mixture accurately. The ideal accuracy range for these devices is typically around +/- 2%. This level of precision is significant in clinical and laboratory settings, where knowing the exact concentration of oxygen is essential for patient care and safety.

Maintaining an accuracy of +/- 2% allows healthcare professionals to make informed decisions regarding oxygen therapy, ventilatory support, and other respiratory interventions that depend on precise oxygen measurements. Recognizing this accuracy level is critical for interpreting results and ensuring that patients receive the optimal oxygen concentrations needed for their specific conditions.

Other accuracy ranges mentioned, such as +/- 1%, +/- 5%, and +/- 10%, do not align with the standard performance capabilities of electrochemical oxygen analyzers under ideal conditions. They may refer to other types of analyzers or be less suitable for clinical applications where accuracy is paramount.
