Intercostal EMGBest for recording respiratory effort signals
Standard eff ort beltsNo representation of the direct breathing eff ortSignals depend strongly on the muscles’ ability to contract (exhausted respiratory pump)Belt positioning determines the correct abdomen/thorax eff ort signalCosts per application • Individual belt sizes needed• Disposable belts or time-consuming cleaning of re-usable belts
Intercostal EMGDirect recording of breathing stimulationSignal refl ects muscle activity directly (electrical signal)Monitoring tool for respiratory insuffi ciency /muscle dysfunction 3,4
Simplicity• One sensor size for all patients• Disposable electrodes, no disinfection / cleaning of the sensor

• For the central apneas cardiac oscillations in the thorax channel may lead to faulty obstruc-tive scoring. For obstructive apnea, as shown in this example, there is no clear eff ort activity for thorax and abdomen channel visible. In contrast the IC-EMG indicates a clear eff ort obst-ruction.
• With a specialized algorithm ECG artefacts are removed and the IC-Eff ort curve is generated.• The calculated IC-Eff ort signal enables a clear distinction between central and obstructive
apnea. The oscillations of the IC-Eff ort signal diff er signifi cantly for both cases.
