Q: what is a low oxygen level in the blood considered?

Sats <90%: Oximeter showing <90% or more appropriately pao2 <58 is considered hypoxia and need for o2 supplemental oxygen will be needed.

Q: please tell me what can cause low oxygen level in the blood ?

Hypoxia: Anything that decreases o2 diffusibility or increases o2 consumption. These will include copd, pulmonary fibrosis and interstitial lung diseases, asthma exacerbation due to decreased lung volume same as in lung resection, pe, later part of chf, sepsis.

Q: is a constant blood oxygen level of between 88 and 94, a reason for concern?

Need follow up: Below 90% typically requires supplemental oxygen and is not normal.

Q: might i increase my oxygen level in my blood by exercising even when i have anaemia?

Anemia means: Low hemoglobin, low oxygen carrrying capacity. So, higher fio2 or exercise could increase dissolved o2, without increasing adequate delivery to your organs...If not, we would have no need for blood.

Question 1

my arterial blood gas says p02 is 72 and the oxygen saturation is 95 and calcium (ionised) 1.12 . are these normal numbers?

Accepted Answer

: Such numbers suggest the "ABG" was actually obtained from a vein, not the artery. A saturation of 95% would  correlate with an arterial blood gas above pAo2 94.

Question 2

are low blood oxygen levels normal?

Accepted Answer

High is good.: Well you would anticipate 95 to 100% oxygen saturation for a young healthy adult. The lower the oxygen saturation the more concern.

Question 3

i need to know what's an optimal blood oxygen level?

Accepted Answer

Depends: On your age and condition . It is usually reported by%.  For example a little baby you would want to be high, close to 100% and if sick not lower than 92% when ill and hospitalized. A normal person walking around is usually 96- 100%. If a person has a chronic lung condition lower percentages of oxygen are acceptable, down to about 88%.

Question 4

how accurate is blood oxygen levels when you took it in a smartwatch?

Accepted Answer

: The Smartwatch is quite accurate. If you compare readings in the physician,s office, this will provide an indication of the accuracy of the home devices. There have been a few problems though with the accuracy of some devices. Correlate to your symptoms, if you are experiencing shortness of breath, fever ,cough or other symptoms, please let your physician know.

Question 5

what exactly does it mean if you have high oxygen levels in your blood?

Accepted Answer

Ambient air is about: 21% o2, and healthy lungs produce a po2 of 80-100%.  Babies in nicu's treated with 100% due to respiratory immaturity could get pulmonarty and retro lentar fibrosis.  One does not do well with higher levels of o2.  Like goldylocks, not too little, not too much: just right.

Question 6

what causes low oxygen level in the blood ?

Accepted Answer

Many things...: Many things can cause a low oxygen level in the blood: so many, in fact, that i don't have enough room here to name them all. 

Here are some common causes: pneumonia; heart failure; clots to the lungs; emphysema; asthma. 

Hope this helps...
