2022年2月18日 · An arterial blood gas (ABG) test is a blood test that requires a sample from an artery in your body to measure the levels of oxygen and carbon dioxide in your blood. The test also checks the balance of acids and bases, known as the pH balance, in your blood.

2023年7月17日 · A blood gas test measures the amount of oxygen and carbon dioxide in the blood. It may also be used to determine the pH of the blood, or how acidic it is. The test is commonly known as a...

2016年6月12日 · Arterial blood gas (ABG) interpretation is something that can be difficult to grasp initially (we’ve been there). We’ve created this guide, which aims to provide a structured approach to ABG interpretation whilst also increasing your understanding of each result’s relevance.

Interpreting an arterial blood gas (ABG) is a crucial skill for physicians, nurses, respiratory therapists, and other health care personnel. ABG interpretation is especially important in critically ill patients. The following six-step process helps ensure a complete interpretation of every ABG.

2024年8月15日 · Arterial blood gases (ABGs) are an important routine investigation to monitor the acid-base balance of patients. 1 They may help make a diagnosis, indicate the severity of a condition and help to assess treatment. ABGs provide the following information: Oxygenation. Adequacy of ventilation. Acid-base levels.

2025年1月16日 · What Is an Arterial Blood Gas Test (ABG)? An arterial blood gas (ABG) test measures oxygen and carbon dioxide levels in your blood. It also measures your body’s acid-base (pH) level, which is...

2024年11月3日 · What Is the ABG Test? An arterial blood gas (ABG) test measures the oxygen and carbon dioxide balance in your blood. It also measures the pH or acid-base balance in your blood. ABG tests are used to evaluate lung and kidney functions and the body's metabolic state.

血气分析（BG）是应用血气分析仪，通过测定人体血液的H+浓度和溶解在血液中的气体（主要指CO2、O2），来了解人体呼吸功能与酸碱平衡状态的一种手段，它能直接反映肺换气功能及其酸碱平衡状态。 采用的标本常为动脉血。 适用于：低氧血症和呼吸衰竭的诊断；呼吸困难的鉴别诊断；昏迷的鉴别诊断；手术适应证的选择；呼吸机的应用、调节、撤机；呼吸治疗的观察；酸碱失衡的诊断等。 血气分析仪可直接测定的有动脉氧分压（PaO2）、动脉二氧化碳分压（PaCO2） …

2024年1月8日 · An arterial blood gas (ABG) explicitly tests blood taken from an artery. ABG analysis assesses the patient's partial pressures of oxygen (PaO 2 ) and carbon dioxide (PaCO 2 ). [2] PaO 2 provides information on the oxygenation status, and PaCO 2 offers information on the ventilation status (chronic or acute respiratory failure).

Blood gases are a measurement of how much oxygen and carbon dioxide are in your blood. They also determine the acidity (pH) of your blood. Usually, blood is taken from an artery. In some cases, blood from a vein may be used (venous blood gas). Most commonly, blood may be collected from one of the following arteries:
