SAO2和SPO2之间的差异

Thekey differencebetween SAO₂和Spo₂is in the type of measurement of O₂血液中的水平。sao₂or Saturation of Oxygen is the direct measurement of O₂bound to heme protein of血红蛋白in the blood. SPO₂measurement or oximetric measurement of O₂bound to hemoglobin is an indirect measurement of saturation of haemoglobin with O₂.

sao₂和Spo₂在不同的疾病条件下测量以监测可用O的水平₂in hemoglobin. The saturation levels of O₂bound to hemoglobin will provide details regarding the efficiency of the alveolar lung system.

What is SAO₂?

O的饱和度₂(SAO₂）在血液中定义了用O占用的血红蛋白结合位点的百分比_2.Each hemoglobin molecule can occupy four O₂molecules as it can allosterically modify its conformation to facilitate binding of O₂to its binding site. The normal SAO₂value of a healthy individual occurs between 95 – 100 %. However, this may increase during conditions such as红血球增多症和hyper ventilation. SAO₂decreases during anemia, hypoventilation, andbronchospasm.

The co-oximeter measures SAO2. The ratio between oxyhemoglobin to all other types of hemoglobin provides the SAO₂value. Other types of hemoglobin include deoxyhemoglobin, methaemoglobin, carboxyhemoglobin, sulfhemoglobin and carboxy sulfhemoglobin.

What is SPO₂?

Spo₂或通过脉搏血氧仪测量的氧饱和度测量可测量血红蛋白的功能饱和度。Spo₂is the ratio between the amount of oxygenated hemoglobin to the sum of deoxyhemoglobin and oxyhemoglobin. Thus, the SPO₂价值不会与圣经相同₂value.

这种获得O饱和的方法₂in hemoglobin is more efficient and rapid in comparison with the co-oximeter measurement.

Spo₂levels in a healthy individual should be more than 94%. The levels can increase or decrease for different health conditions as in SAO₂.

圣经之间有什么相似之处₂和Spo₂?

• Both SAO₂和Spo₂depend on the concentration of O₂in blood.
• sao₂和Spo₂measure the saturation of O₂in haemoglobin.
• Both the levels of SAO₂和Spo₂高通风期间增加。
• 圣人₂和Spo₂levels decrease during hypo ventilation and anaemic.

圣经有什么区别₂和Spo₂?

sao2vs SPO2
sao2 is the direct measurement of O2 bound to heme protein of haemoglobin in the blood.	Spo2 measurement is the oximetric pulse measurement of functional saturation of haemoglobin with O2.
Saturation Level in a Healthy Individual
sao2 in healthy person should be 95 – 100%.	Spo2 in healthy person should be more than 94%.
用于测量的设备
Co-oximeter is used to measure SAO2.	脉搏血氧仪用于测量SPO2。
所用技术的侵入性
Invasive technique is used to measure SAO2. It uses the measurement of O2 saturation in arterial blood.	No-invasive technique is used to measure SPO2. It uses earlobes or fingertips for measurement.
速度
sao2 measurement is slower than SPO2	Spo2 measurement is raid than SAO2
Efficiency
效率较低。	更高效。

概括– SAO2 vs SPO2

Measurement of O₂saturation levels is very important during disease conditions to assess the respiratory levels and to check for cardiac and respiratory health. Increase or decrease of these saturation levels indicates the disease conditions. SAO₂和Spo₂它们用于测量O的方法不同₂saturation in blood. That is, SAO₂measures the total O₂bound to haemoglobin using co-oximeter whereas SPO₂测量o₂bound to haemoglobin by pulse oximeter method. Further, SAO₂is a direct measurement of saturation of O₂in the blood while SPO₂is an indirect measurement of SAO₂. This is the difference between SAO₂和Spo₂.
