BACKGROUND Hypercapnia is abnormally high arterial partial pressure of carbon dioxide (CO₂). CO₂ can affect redox signaling mechanisms, leading to production oxidative derivatives. Thiol formed by attaching a sulfhydryl group atom. Under stress, it forms covalent bonds called thiol disulphide bonds. Serum albumin modified ischemia-modified (IMA) exposure free radicals. This case-control study aimed evaluate thiol/disulphide homeostasis and IMA levels in 61 patients with hypercapnia. MATERIAL...
