When your body doesn't have enough oxygen, you could get hypoxemia or hypoxia. These are dangerous conditions. 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. The word hypoxia is sometimes used to describe both problems.
To diagnose asthma, your doctor will review your asthma symptoms, your medical and family history, and may perform lung function tests (also called pulmonary function tests). Your doctor will be interested in any breathing problems you might have had, as well as a family history of asthma or other lung conditions, allergies, or a skin disease called eczema. It is important that you describe your symptoms of asthma in detail (coughing, wheezing, shortness of breath, chest tightness), including when...
You'll need to go to the hospital to get treatment for hypoxia and to keep a check on your oxygen level.
The most important thing is to get more oxygen into your body. You'll receive it through a small plug in your nose or through a mask that covers your nose and mouth. For many people, this is enough to bring your oxygen level up to normal.
An inhaler or asthma medicine by mouth can make breathing easier. If these don't help, the doctor might try giving you medicine through a vein in your arm (an IV). You might also need steroid drugs for a short time to shrink inflammation in your lungs.
When your life is in danger and other treatments aren't working, you may need a machine to help you breathe.
Causes of Hypoxia
A severe asthma attack, or flare, can cause hypoxia in adults and kids. During an attack, your airways narrow, making it hard to get air into your lungs. Coughing to clear your lungs uses even more oxygen and can make symptoms worse.
