Symptoms of low oxygen levels
- when oxygen saturation is low
- when sleeping oxygen level is low
- when oxygen level is too low
- when blood oxygen concentration is low
What happens when your oxygen level drops to 70.
What Is Hypoxemia?
Hypoxia and hypoxemia refer to two different things.
Normal oxygen saturation by age
While hypoxemia refers to low oxygen levels in your blood, hypoxia refers to low levels of oxygen in the tissues of your body.
The two can sometimes, but not always, occur together. For example, hypoxia can happen in the absence of hypoxemia if blood flow to an organ or tissue is disrupted.
In this case, the blood may have normal levels of oxygen, but it can’t reach the affected area.
Generally, the presence of hypoxemia suggests hypoxia. This makes sense because if oxygen levels are low in your blood, the tissues of your body are also probably not getting enough oxygen either.
You should always seek emergency medical attention if shortness of breath happens suddenly and makes it hard for you to breathe.
Make an appointment with your doctor if you experience any of the following symptoms:
- shortness of breath that occurs with minimal activity or when you’re at rest
- shortness of breath that occurs with exercise and gets worse
- waking suddenly from sleep with shortness of breath
