Record at least 5 artifacts-free breaths once the patient is ready. Encourage the patient to breathe in a relaxed and stable manner during the measurement. RESTECH validated algorithms will analyze the data and exclude, in real time, breaths with cough, glottis closure, or irregular breathing. Onscreen results will be displayed only for artifacts-free breaths.
During the measurement inspect the value of CoV (coefficient of variability) of Rtot of all the accepted breaths and minute ventilation (Ve) displayed on the right part or the screen. Ensure that:
- CoV Rtot is≤ 30%
- Ve is ≤18 L/min
These criteria help verify that all artifacts have been excluded by the device, and data have been recorded while the patient breathes in a relaxed and stable manner. In RESMON PRO, the system indicates these conditions in RED if Ve or CoV of Rtot exceeds the specified limits.
RESTECH suggests to discard measurements presenting Within-measurement CoV of Rtot > 30% and/or Ve>= 18 L/min
