Rapid-response infrared (NDIR) sensors provide the highest accuracy for DLCO testing because they offer response times under 100 milliseconds. This speed is vital for capturing the gas concentration changes during a single-breath manoeuvre. When performing a gas analyser comparison, you’ll find that NDIR technology maintains 0.1% stability over a 24-hour period. We recommend this technology to ensure your patients receive the most precise diagnostic results possible for their respiratory health.
