Intratidal nonlinear mechanics of the respiratory system during anesthesia for laparoscopic surgery
- Conditions
- respiratory system mechanics of patients during laparoscopic surgery
- Registration Number
- DRKS00004325
- Lead Sponsor
- Anästhesiologische Universitätsklinik Freiburg
- Brief Summary
Pneumoperitoneum during laparoscopic surgery causes intratidal recruitment/derecruitment which partly persists after its removal. The analysis of the intratidal volume-dependent CRS profiles could be used to guide intraoperative PEEP adjustments during elevated intraabdominal pressure.

- Not specified
- Primary Outcome Measures
Name Time Method The temporal courses of aiirwa pressure, flow rate, esophageal and gastric pressure are recorded. In an offline analysis the intratidal compliance course will be calculated.
- Secondary Outcome Measures
Name Time Method During the experiment oxygenation will be recorded. The data alalysis will be performed after the experiment.
