What Is Hypoxia And Why Is It So Dangerous?
For the average person, oxygen deprivation poses an imminent threat. The timeline from initial hypoxia to death or brain damage varies with the degree of oxygen deprivation. Minor oxygen deprivation only causes damage over time, but true hypoxia triggers near-instantaneous damage.

hypoxia Definition, Types, Physiological Effects Britannica.com.
The hypoxemic type of hypoxia is due to one of two mechanisms: 1 a decrease in the amount of breathable oxygenoften encountered in pilots, mountain climbers, and people living at high altitudesdue to reduced barometric pressure see altitude sickness or 2 cardiopulmonary failure in which the lungs are unable to efficiently transfer oxygen from the alveoli to the blood.

What is Hypoxia?
Hypoxia may also be caused by conditions such as heart failure, cardiac arrest or heart attack when the circulation of blood is slowed down and therefore inadequate amounts of oxygen are supplied to the body. Healthy people may also suffer from hypoxia.
Hypoxia and Hypoxemia: Symptoms, Treatment, Causes.
Without oxygen, your brain, liver, and other organs can be damaged just minutes after symptoms start. Hypoxemia low oxygen in your blood can cause hypoxia low oxygen in your tissues when your blood doesn't' carry enough oxygen to your tissues to meet your body's' needs.

Hypoxemia and Hypoxia SpringerLink.
It is not measured directly by a laboratory value though an increased arterial lactate level usually accompanies tissue hypoxia. Hypoxia and hypoxemia may or may not occur together. Generally, the presence of hypoxemia suggests hypoxia. However, hypoxia may not be present in patients with hypoxemia if the patient compensates for a low Pao 2 by increasing oxygen delivery.
