Low blood pressure or low oxygen saturation (%).
All blood coming from the heart travels through arteries but not all have high levels of oxygen.The blood that goes to the body is high in oxygen but the blood that goes to the lungs is low in oxygen.There it drops of carbon dioxide and picks up oxygen and carries this back to the heart to be pumped out to the body.
An ECG won't show oxygen levels in the blood - it simply records the patients heartbeat.

The blood vessel that carries deoxygenated (low oxygen) blood away from the heart is called the pulmonary artery. This artery carries blood to the lungs where it picks up oxygen and then travels back to the heart to be pumped out to the cells of the body. The best way to remember this is to remember that pulmonary means lungs and artery means a blood vessel that carries blood away from the heart. Most arteries carry blood that is rich in oxygen. The pulmonary artery is an exception.
Deoxygenated blood is low in oxygen and high in carbon dioxide.
the quality of our blood that rich with oxygen will become low
erythropoiesis is triggered by low oxygen levels.
hypoxemia
Arteries carry blood high in oxygen away from the heart to the rest of the body. The blood in arteries is oxygenated, while veins carry blood low in oxygen back to the heart.
The right atrium and right ventricle of the heart contain blood low in oxygen. This blood returns from the body and is then pumped to the lungs in order to pick up oxygen.
Low oxygen/de-oxygenated blood is carried by:all the veins (except the pulmonary vein)the pulmonary artery.
Blood low in oxygen enters the right atrium of the heart through the superior and inferior vena cava.
Same blood as everywhere else. The difference is the gases in the blood: it enters the lungs low on oxygen and high in CO2, it leaves high in oxygen and low in CO2.
The heart pumps blood low in oxygen and high in carbon dioxide to the lungs, where blood releases carbon dioxide and picks up oxygen.
Low blood oxygen has many causes, often respiratory disorders, and can cause tissue hypoxia as the blood is not supplying enough oxygen to the body. Hypoxemia is the medical term used to refer to this condition.
low blood pressure leads to an insufficient transport of oxygen through the body
