What Is Good Oxygen Saturation
The value obtained from arterial blood gases or abgs sao2 describes the oxygen saturation of arterial blood and is obtained by drawing blood from an artery such as the radial artery in the wrist or the femoral artery in the groin. Normal arterial oxygen is approximately 75 to 100 millimeters of mercury mm hg.
Oxygen saturation levels measure the degree to which the haemoglobin contained in the red blood cells erythrocytes has bonded with oxygen molecules.
What is good oxygen saturation. A normal blood oxygen level varies between 75 and 100 millimeters of mercury mm hg. A measurement of your blood oxygen is called your oxygen saturation level. The two most common ways of assessing the saturation of oxygen in the blood are arterial blood gases abg and pulsatile oxygen.
Oxygen saturation is measured by pulse oximetry which uses a sensor of two light sources that hemoglobin absorbs then transmits through the bodys tissues. A pulse oximeter is a small device which clips on a finger and measures oxygen saturation in the blood a measurement which is usually considered to be the equivalent of blood oxygen levels. The body requires a specific amount of oxygen in your blood to function properly.
A reading below 95 percent in a healthy person with normal lung function indicates low oxygen levels in the blood a condition medically termed hypoxemia that requires medical investigation. Abgs are measured in millimeters of mercury mm hg. Oxygen saturation refers to the amount of oxygen thats in your bloodstream.
A blood oxygen level below 60 mm hg is considered low and may require oxygen supplementation depending on a. In a healthy person oxygen saturation levels in arterial blood fall between 95 and 100 percent according to the world health organization who 3. A normal oxygen level is 95 to 100 percent oxygen as measured by pulse oximetry says the mayo clinic.
In short blood oxygen saturation is the amount of oxygen within a blood cell. It can also be estimated by measuring the oxygen saturation of your blood using a pulse oximeter a small device that clips to your finger. Oxygen is taken in by the lungs when we breathe in.
Oxygen saturation refers to the level of oxygen carried by red blood cells through the arteries and delivered to internal organs. In medical shorthand you may hear it called a pao 2 when using a blood gas and an o 2 sat spo2 when using a pulse ox. The normal range of oxygen saturation for adults is 94 to 99 percent.
The importance of this concept rests on the fact that higher levels of blood cell oxygen saturation will ultimately permit easier breathing and reduced shortness of breath. Hypoxemia is determined by measuring the oxygen level in a blood sample taken from an artery arterial blood gas.
