Can transcutaneous carbon dioxide and oxygen pressure predict arterial carbon dioxide and oxygen pressure during laparoscopic bariatric surgery?

ABSTRACT

Objective: In bariatric surgery, arterial carbon dioxide [PaO[2]] and oxygen [PaO[2]] pressures are important but sometimes difficult to measure. The purpose of the present study was to investigate whether transcutaneous carbon dioxide [tcPCO[2] and oxygen [tcPO[2] pressures can be used to monitor [PaO[2]] and [PaO[2]], respectively, in laparoscopic bariatric surgery
