A sidestream gas analyzer is characterized by its use of a continuous pump system to sample gases from the ventilatory circuit or breathing system. The continuous pumping mechanism allows the analyzer to draw a small continuous stream of gas for analysis, which is crucial for providing real-time data regarding the composition of gases being delivered to the patient.

Importantly, to maintain the integrity of the system and to ensure accurate readings, the analyzer should never be allowed to empty into room air. This would risk contamination of the sample and produce misleading results, as direct exposure to room air would alter the measurements being taken.

While other options presented may describe certain aspects of gas analyzers, they do not accurately capture the essential functioning characteristics of a sidestream gas analyzer, particularly its reliance on a continuous pump system that is integral to its operation and accuracy in analysis.
