When selecting an ETCO₂ (end-tidal carbon dioxide) monitoring device, many people focus on the specifications: measurement range, accuracy, response time, etc. In practice, however, what truly impacts reliability and user experience is how the device performs in long-term, real-world clinical environments.
Accuracy
The reliability of ETCO₂ readings depends not only on the sensor itself but also on how the device ensures measurement precision. Sidestream ETCO₂ monitors typically use automatic zeroing, completing calibration at startup to ensure accurate and consistent measurements. Mainstream ETCO₂ monitors, on the other hand, generally require manual zeroing, performed by the operator before use or at specific intervals. Kingst’s design takes these differences into account, ensuring reliable measurements across various clinical environments while alerting users if any issue arises.
Stability
In clinical settings, ETCO₂ measurements can be affected by interfering gases such as supplemental oxygen, volatile anesthetics, or other inhaled medications, which can alter the composition of the sampled gas and impact readings. Moisture, secretions, or changes in patient breathing patterns can also interfere. Kingst’s devices are designed to minimize these effects, providing readings that closely reflect true patient conditions and issuing alerts when abnormalities occur.
Usability
ETCO₂ monitoring is not limited to bedside use—it may also be needed during patient transport, emergency care, or handheld monitoring. High usability means the device can deliver continuous, reliable data across different scenarios with minimal intervention. By integrating ETCO₂ devices with a data platform, Kingst enables trend monitoring and continuous recording, giving clinical teams a clear and confident view of patient status.
Specifications only tell you what a device can measure. True value comes from how product design ensures reliable performance in real-world use. Kingst applies this system-level thinking to every device, making monitoring safer and more efficient.
