Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The number and nature of (serious) adverse device effects related to the turbine-based insufflator that occur during use. | — |
Secondary
| Measure | Time frame |
|---|---|
| - Determination of pressure stability throughout all procedures. - Identification of events that impair insufflation pressure stability. - Determination of the gas volume exchange required to keep insufflation pressures stable, absolute and in relation to ventilation tidal volumes. - Investigation of ventilator action and insufflator response in terms of amplitude and temporal offset. - Comparison between the insufflation pressure chosen by the surgeon and the optimal pressure derived from endoscopic oscillometry. - Evaluation of the applied pressure amplitudes and frequencies needed basing on patient*s weight and size, in order to get reference values of the abdominal cavity*s compliance [L/hPa] in humans. - Evaluation of flows generated by the oscillation pressures applied for the purpose of sizing measuring instruments (flowmeters). - Evaluation of the range of frequencies used in oscillometry on patients* size and weight for estimating the compliance. - Comparison of pressure and flow time tracing both in ventilation and insufflation to derive the static compliance of the respiratory system. - Compensation of ventilation effects on pressure and flow signals. A post-processing analysis of the acquired signals will be done in order to filter out these effects and retain the information on the applied forced oscillations. - Optimization of endoscopic oscillometry in patients with different breathing rates. | — |
