ABG CBG和VBG有什么区别|比较类似术语之间的差异

这关键区别在ABG CBG和VBG之间是ABG测试使用了从动脉当CBG测试使用从中抽取的血液毛细血管，，，，and VBG test uses blood drawn from a静脉。

进行血气分析是为了评估氧气和二氧化碳，酸碱平衡和肺效率的水平。ABG，CBG和VBG是出于共同目的进行的三种测试。ABG代表arterial blood gas而CBG代表capillary blood gas，，，，and VBG stands for静脉血气。Out of the three test types, ABG is the most effective test. However, due to certain conditions of patients (severity and age), CBG and VBG are performed as alternate methods.

什么是ABG？

ABG或arterial blood gasis a test that measures the different parameters of blood moving along an artery. In a healthy individual, when the blood moves, passing through the lungs, oxygen moves into the blood, and carbon dioxide moves out of the blood effectively. ABG test provides a quantitative and qualitative measurement for the effectiveness of lungs to transport oxygen into the blood and remove carbon dioxide from the blood. An ABG test measures分压of oxygen, partial pressure of carbon dioxide, pH, bicarbonate, oxygen content, and oxygen saturation.

进行此测试是为了评估与肺和呼吸有关的不同疾病。ABG测试主要是为了检查严重的呼吸困难和肺部疾病。这些疾病包括囊性纤维化，哮喘和COPD（慢性阻塞性肺疾病）。除此之外，ABG测试还可以评估肺部功能水平，额外氧气的需求并测量肾衰竭，心力衰竭和不受控制的糖尿病患者的酸碱血液水平。ABG测试是通过从径向动脉（手腕内）从动脉中抽血来完成的。但是股动脉和肱动脉也用于吸收血液进行测试。

什么是CBG?

CBG或capillary blood gasis a test performed in infants or kids and elderly patients with fragile veins. This test asses parameters such as oxygen, carbon dioxide, and acid-base balance. CBG is an alternative test to ABG and is performed only when sampling is difficult, especially in neonates, infants, small kids, and elderly patients with fragile veins. Severe respiratory disorders that occur in such groups of individuals need to be treated immediately in order to prevent complications. Hence, capillary blood gas test is a vital method practiced at different medical institutes.

在此测试期间，通过在高血管形成的地方刺穿皮肤皮肤层来抽取血液。通常，在测试之前，血管化区域会变热以扩张血管并加速血液。这也减少了动脉压力和钢筋压力之间的差异。CBG测试是由于几个原因进行的。这些包括无法获得血液分析的静脉或动脉通道，经皮氧值的异常读数，末端潮汐二氧化碳值，脉搏血氧饱和度值。此外，CBG是为了最大程度地减少婴儿的多种动脉和静脉血液抽水，以避免腹侧或动脉进入，从而降低感染的风险。CBG测试包括几种罕见的并发症，例如感染，神经损伤，血肿，皮肤分解和骨骼钙化。

什么是VBG?

VBG或静脉血气是一种传统的测试，用于分析通风条件和血酸基平衡。当个体由于外周血循环不良或低血压而导致脉冲减少时，这是作为动脉血气（ABG）测试的替代方法。在正常水平下，通过通过静脉穿刺抽取的静脉血液样本进行VBG测试。

VBGis a convenient test, especially in intensive care units since patients already have a central venous catheter. Instead of the central venous blood sample, VBG test is performed by peripheral venous sample (by peripheral venous catheter) or mixed venous sample (from distal port of pulmonary artery catheter). Instead of peripheral venous blood gases, central venous blood gasses are preferred more since they correlate well with arterial blood gases and are proven by research and clinical experience. A VBG test provides venous oxygen tension, carbon dioxide tension, acidity, haemoglobin saturation, and serum bicarbonate concentration. Generally, specimen volume is 01 mL (minimum 0.5 mL), and it is stable for 30 minutes.

ABG CBG和VBG之间有什么相似之处？

ABG，，，，CBG, and VBG are blood gas tests.
All three types of tests analyze similar parameters.
这main analyzed parameter that is common to all three tests is the effectiveness of the lungs for gas exchange.
全血是所有三个测试的标本类型。
All three tests use a specimen of 1 mL with a minimum of 0.5 mL

ABG CBG和VBG有什么区别?

ABG使用动脉血液，而CBG使用毛细血管血液，而VBG使用钢丝。因此，这是ABG CBG和VBG之间的关键区别。ABG是临床上最重要的测试。但是由于获得样品的各种困难，CBG和VBG是进行了两个替代测试。CBG是针对具有脆弱动脉和静脉的婴儿和成年人进行的。VBG很常见，在重症监护病房中使用了更多。

以下信息图显示了与表格形式的ABG CBG和VBG之间的差异，以与并排比较。

Summary – ABG vs CBG vs VBG

血液测试评估氧气和二氧化碳，酸碱平衡和肺效率的水平。通过抽血的类型，有三种类型的测试，例如ABG，CBG和VBG。ABG是临床上最重要的血液测试，而CBG和VBG作为替代测试进行。CBG是针对婴儿和脆弱静脉和动脉的老年患者完成的。所有三个测试共有的主要分析参数是肺对气体交换的有效性。全血是所有三个测试的标本类型。因此，这是ABG CBG和VBG之间差异的摘要。
