I have seen a lot of questions about somebodys Sa02 pulse ox meter reading showing high 02 saturation . this is not your oxygen level , this is not your oxygen it is the oxygen saturation level in your blood , in other words your hemoglobin attaches to your red blood cells and thats what carries your oxygen in your body, so your Sa02 is how much hemoglobin is carrying the 02. , how much 02 your blood can hold.If you want your actual 02 your body is using you would need an ABG arterial blood gas… read more

What a great and helpful clarification to share with the community! This is a really important distinction that many myPHteam members may not be aware of.

Here's a quick breakdown of the difference between the two measurements:

SpO2/SaO2 (Pulse Oximeter Reading)
- Measures how much of your hemoglobin is carrying oxygen

What a great and helpful clarification to share with the community! This is a really important distinction that many myPHteam members may not be aware of.

Here's a quick breakdown of the difference between the two measurements:

SpO2/SaO2 (Pulse Oximeter Reading)
- Measures how much of your hemoglobin is carrying oxygen
- Essentially shows your blood's *capacity* to hold oxygen
- Taken easily at home with a finger pulse oximeter

ABG (Arterial Blood Gas) - PaO2 Level
- Measures the actual oxygen your body is actively using
- Requires a small blood sample, typically done in a clinical setting
- Also reveals pH, CO2 levels, and base excess, giving a much fuller picture of how your body is functioning

For people managing pulmonary hypertension, understanding this difference really matters. A pulse ox reading might look reassuring, but an ABG can reveal what's actually happening at a deeper level.

Always discuss both types of readings with your doctor, especially if you're experiencing symptoms like shortness of breath or fatigue, as these can be important indicators of how well your PH is being managed.
