Lower end-tidal co2 levels are linked to an increased risk of postoperative pulmonary complications after surgery.
Patients with low end-tidal co2 faced a 34% complication rate, significantly higher than the 23% rate in those with normal-high levels.
Analysis included data from nearly 2800 participants across two randomised clinical trials focused on ventilation strategies.
Finding highlights the need for careful monitoring of end-tidal co2 to minimize postoperative risks in surgical settings.
