blood pxygen Flashcards
the amount of oxygen circulating in the blood
blood oxygen
can lead to many serious conditions and damage to individual organ systems, especially the brain and heart. Low blood oxygen levels indicate that the lungs and circulatory system may not be working as they should.
low blood oxygen levels (hypoxemia)
Two Ways to Check Blood Oxygen Level
Using Pulse Oximetry, Oxygen level blood draw test
can also measure blood oxygen saturation levels through a small clip that’s usually placed on your finger or toe. An oximeter reading only indicates what percentage of your blood is saturated with oxygen, known as the SpO2 level, as well as your heart rate. It’s a quick and harmless way to check if someone’s blood oxygen level is too low.

Healthcare providers can measure your blood oxygen level as part of a larger test known as an
arterial blood gas (ABG) test
measures the level of oxygen and carbon dioxide in your blood
ABG test
The test also checks the balance of acids and bases, known as the pH balance, in your blood.

The healthcare care provider may also perform a blood oxygen test if have any of the following lung conditions to make sure that treatment is working properly:
Asthma
Chronic obstructive pulmonary disease (COPD)
CYSTIC fibrosis
Heart Disease
normal pulse oximeter reading for your oxygen saturation level is between
95% and 100%.
oxygen saturation levels may also be__ if you live in an area with high elevation.
lower
It’s important to note that pulse oximeters are not always accurate. Your actual blood saturation level maybe_____ higher or lower than what the oximeter reads.
2% to 4%
A lower-than-normal blood oxygen level is called
hypoxemia
Call your healthcare provider if you’re using an oximeter at home and your oxygen saturation level is ____. if its at ____, get to the nearest emergency room
