What color is your blood before it hits oxygen?

Your blood is always red, but it changes from a bright, cherry red (oxygenated) to a dark, deep red (deoxygenated) when it has delivered oxygen, not blue; it only looks bluish through your skin due to light filtering and skin thickness. The iron in hemoglobin gives blood its red color, and this shade deepens when oxygen levels are lower.

How do I raise my oxygen level quickly?

To increase your oxygen level immediately, practice deep breathing (diaphragmatic or pursed-lip), sit or stand up straight (tripod position), get fresh air, and stay hydrated; these methods help maximize lung capacity and oxygen intake, but seek urgent medical help if you have severe symptoms like difficulty breathing, as these natural remedies might not suffice.
 

Should I go to the ER if my oxygen level is 92?

If you're using an oximeter at home and your oxygen saturation level is 92% or lower, call your healthcare provider. If it's at 88% or lower, get to the nearest emergency room as soon as possible.
