How do Dymedix Sensors compare to air pressure transducers?
A. Dymedix Sensors are superior to Air Pressure Transducers in accurately detecting mouth breathing, even when compared to oral/nasal cannula. Dymedix sensors have demonstrated, in clinical studies, better accuracy in scoring apneas and hypopneas. Air Pressure transducers have demonstrated the following issues: · Reductions in nasal air flow due to mucus or anatomical issues, which may cause false positives. · Increased nasal flow resistance due to the introduction of the probes into the patient’s nares. · Misalignment of the nasal prongs during patient movement can cause false positives. · Non-linearity of pressure transducers. This means that they do not accurately track changes in the amplitude of the airflow signal and tend to overscore apneas and hypopneas. · Cannot be used simultaneously with end-tidal CO2 or oxygen cannula.
