We present an animal model used to evaluate the in vivo performance of electrochemical amperometric continuous lactate sensors compared to blood gas instruments. Electrochemical lactate sensors were fabricated. placed into 5 Fr central venous catheters (CVCs). and paired with wireless potentiostat devices. https://safeersappliancers.shop/product-category/beko-pro-wdix8543100-integrated-8-5kg-1400-spin-washer-dryer-white/
