Final answer:
Hypoxemia is the condition that results from low oxygen levels in the blood due to respiratory disorders or heart conditions. It can cause symptoms such as fatigue and shortness of breath.
Step-by-step explanation:
The condition that results from low oxygen levels in the blood is hypoxemia. Hypoxemia can be caused by respiratory disorders or heart conditions that impede the lungs' ability to oxygenate the blood effectively.
For example, pneumonia, a condition in which the lungs fill with mucus, can lead to hypoxemia. The mucus obstructs the airways, making it difficult for oxygen to reach the bloodstream. This results in low oxygen levels in the blood.
Hypoxemia can cause symptoms such as fatigue, headaches, confusion, and shortness of breath. It is important to address the underlying respiratory or heart condition to improve oxygenation and prevent further complications.
