What is the difference between dyspnea and hypoxia. What is worse. Why?

Dyspnea or short of breath (SOB) is perceived difficulty breathing or painful breathing. It is a common symptom of numerous medical disorders.

Hypoxia : a shortage of oxygen in the body. Hypoxaemia is the reduction of oxygen specifically in the blood; anoxia is when there is no oxygen available at all.

You can't compare which is worse because :
Dyspnea is symptoms, hypoxia is the result (of dyspnea/apnea).

dyspnea- shortness of breath

hypoxia- lack of oxygen to the brain.

hypoxia is worse.

dyspnea = difficulty breathing. subjective. you can have difficulty breathing, but still have a normal blood oxygen gas level.

hypoxia = a blood oxygen gas level (oxygen saturation) less than 85%.

hypoxia would require hook-up to an oxygen mask at least. treatment of dyspnea would relate to the root cause of the difficulty.

which is worse? clinically, hypoxia.
