Endexpiratory CO2 concentrations were measured in 8 patients who underwent laparoscopy with CO2 insufflation for the performance of sterilization. The CO2 concentrations rose during the first 10 minutes of insufflation, then remained constant. The endexpiratory CO2 then returned to the original levels within 6 minutes after deflation. Cardiovascular disturbances and hypoxia can occur in conjunction with CO2 insufflation and can be avoided by monitoring the endexpiratory CO2 concentrations by infrared absorption spectrometry.
