For blood oxygen saturation level - what is the fatal and normal range?

Oxygen sat curve

Oxygen
if you look at the P50 or oxygen saturation curve, anything above 90% is ok for the hemoglobin to unload as it gets into the tissues and supply them. As the curve goes down to 75% about PaO2 of 45, this nears the saturation in the veins where unloading of oxygen to the tissues including heart muscles becomes difficult and there will be eventual death as it gets lower than that.

My blood oxygen saturation is 96% but can there be chances that my blood is not circulation properly to my skin?

Yes.

Blood
At your age chances of lack of circulation is unlikely unless there are preexisting conditions like diabetes or rheumatologic problems like SLE, etc.. Smoking can also cause it as do some drugs that cause vasoconstriction or closing off of blood vessels.

Dr. Mark Birnbach answered:

In a person with sleep apnea, what causes the rises and falls in oxygen saturation of arterial blood during sleep?

Sleep apnea

Artery
Sleep apnea is defined as stopping breathing for 10 seconds. During that time, the body is not getting any oxygen. In addition , there can be instances that last less than 10 seconds, or where a less than adequate effort to breath is attempted. These also reduce the oxygen intake.

What is a tetralogy of fallot?

TOF

Tetralogy_of_fallot
A type of congenital (present at birth) heart disease that usually causes cyanosis (blue baby). It is characterized by a large hole in the heart (VSD) and obstruction of blood flow to the lungs (Pulmonary Stenosis). Babies born with TOF require surgery during infancy.

Is tetralogy of fallot hereditary?

Depends on variables

Tetralogy_of_fallot
Most cases of complex congenital heart disease happen in a sporadic manner. The general risk of a parent with a CHD having a child in these sporadic forms is about 6%.This is not specific to the same defect but includes all defects.When it is part of an autosomal disorder or chromosome deletion syndrome, the risks are higher.

Could tetralogy of fallot be genetic?

Yes

Genetic_sexual_development_disorders
Definitely, some cases of tetralogy of Fallot have a genetic component. For instance, in 22q deletion syndromes (Digeorge syndrome) one of the common heart diseases is tetralogy of Fallot and variants of tetralogy of Fallot.

what happens with ?tetralogy of fallot?

Heart surgery

Open-uri20140125-5996-1sgq96z
This is a congenital heart defect knows at "tetralogy" because the initial description discussed four findings: 1) ventricular septal defect, 2) overriding aorta, 3) pulmonary stenosis, 4) right ventricular hypertrophy. The cause is abnormal conotruncal septation, giving too much to the outflow to the aorta and not enough to the outflow to the lungs. This defect always requires surgical repair.
