It is known that the difference between the end-tidal CO2 partial pressure (ETCO2) and the arterial CO2 partial pressure (PaCO2) increased progressively and reached more than 10 mmHg during robot-assisted laparoscopic prostatectomy. This increase in the difference between the ETCO2 and the PaCO2 during the surgery provides clinicians with important ...
