Which parameter is routinely monitored during CO2 pneumoperitoneum to assess ventilation status?

• A. End tidal CO2
• B. Platelet count
• C. Blood glucose
• D. Serum sodium

Answer: (A)

End-tidal CO2 monitoring via capnography is used during CO2 pneumoperitoneum to assess ventilation status. The CO2 used to insufflate the abdomen is absorbed into the bloodstream, which can raise arterial CO2 levels (hypercapnia). End-tidal CO2 reflects the CO2 level at the end of exhalation and correlates with arterial CO2 in many anesthetized patients, providing real-time feedback on how well ventilation is removing CO2. This allows quick detection of hypoventilation, excessive CO2 absorption, or changes in airway dynamics, so clinicians can adjust ventilation accordingly. The other parameters listed are not measures of current ventilation: platelet count, blood glucose, and serum sodium relate to other physiological aspects and do not indicate how effectively CO2 is being eliminated from the body.
