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.

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 |

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.

Ken说
-SAO2 is specifically the saturation of arterial O2, as opposed to SVO2 (venous).
-SPO2 levels often remain high with anemia while patient fails to perfuse tissues effectively (measures saturation of hemoglobin, which there may be too few of).
