Arterial blood gas (ABG) analysis is routinely indicated in critically ill patients receiving treatment in intensive care units (ICU) and emergency departments. However, ABG sampling is a difficult and invasive technique, and may even lead to complications in patients. Conversely, venous blood gas (VBG) sampling is simpler and less prone to complications. The study is to analyze the correlation and similarity between ABG values and estimated values from VBG (hereafter referred to as eVBG) based on a specific formula, applied to the same group of patients at a single time point. The descriptive study included 74 patients undergoing ABG analysis in the ICU. The results showed a strong correlation and high similarity between ABG and eVBG values for pO2 and pCO2, with correlation coefficients of r = 0.99 and r = 0.97, respectively. The difference in pO2 and pCO2 values between ABG and eVBG was 4.84mmHg and -3.43mmHg, respectively. The study demonstrated a closetight correlation and tightstrong agreement for these two important parameters (pO2 and pCO2) between arterial blood gas and estimated venous blood gas.Xét nghiệm khí máu động mạch được chỉ định thường quy ở những bệnh nhân (BN) nặng, được điều trị tại các Khoa Hồi sức tích cực và cấp cứu.
